This week on the blog, I am asking you to have a discussion with your classmates about cells.
You can start the conversation by sharing:
Something that you've learned
Something that surprised you
Something that you are interested in knowing more about
Something you have a question about
Then, you can respond (to at least 3 other people).
Let the conversation begin!

As I have been studying I learned that some bacterial cells have a third protective layer.
What surprised me was that there are two different types of D.N.A. found in different cells nucleoid
I know ten times more than I used to know about cells but i would love to learn more about there structure.
Something that I have been wondering since we started on cells is why do they need all these parts.
I learned that cancer cells do not stop reproducing, and they don’t stay together; they separate (that’s how it spreads). I was surprised to find out that some viruses can cause cancer. I am interested to learn more about the parts of a brain cancer cell and what those cell parts do.
I have been curious about where the brain is affected by the cancer.
I learned that cells are alive they don’t have brains ore social lives but they do have jobs and there good at it
im learning about viruses
i've learned there are groups of people that just classify things for a living
it suprised me that.....bacteriophage is a virus when it sound like a type of bacteria
i would like to know how the bacteriophage knows witch cells ot infect
I learned that plant cells divide and make copies of their selves. (A-sexual reproduction.) I was surprised that each cell knows exactly what to let into the cell and what not to let in. I want to learn more about specific types of plant cells and what their jobs are. I have been wondering what happens when something goes wrong in a cell.
I learned that Cancer cells could cause tumors. I was surprised to find out that you can get Cancer from something damaging your DNA. I'm interested in knowing more about Brain Cancer cells. My question is: In Brain Cancer is the cancer cell contained to one part of the brain (one part of the brain) or can the cells move around in the brain? If it can only move inside one part of the brain, which part?
idk345:
To answer your question on where is the brain affected by cancer. The cancer cells are almost always in the central nervous system; the cells rarely spread to outside the central nervous system.
idk345:
I got the information on:
http://www.oncologychannel.com/braincancer/index.shtml
Tony Stewert:
To answer your question about how bacteriophage knows which cell to infect:
I found out that a DNA strand (RNA) tells them to attack certain cells. It's like there is one boss that gives orders and the others just follow orders.
I got this info from:
http://wiki.answers.com/Q/How_does_a_virus_know_what_cells_to_infect
idk345:
I am not studying cancer cells, but after reading your blog... I realized that because cancer cells never stop reproducing, that is probably why cancer is so (sadly) popular.
my question on cancer-cells:
Are certain cancer cells, or just cancer cells in general attracted to different people? How do they "choose
" who they will go to?
As I have been studying Bacteria cells, something that I've learned is that how they look can surprise you. While I expected that they would look like viruses, (A dark, spiky ball, or a six-legged walking 'spider'), they look more like fat worms.
What surprised me is above, how they looked.
Something that I'm interested in is their cell structure.
One thing I'm curious about is the question of why they look like worms.
Thank you 'Pony Girl' for answering that question i had.
have a great day: i might be worog but i think when somthing goes wrong with a cell it dies and new cells replace it
milkman: I think the reason that cells need all these parts is because each one takes a part in helping the cell do one or more charisteristics of life. (like the chart we have been making.)
I have been learning about plant cells and during this research i learned that even though the plant and animal cell are almost the same there is a few differences between them. How a plant cell has a CELL WALL, and a CHLOROPLAST and animal cells don't have a CELL WALL because animal cells have other forms of support like exoskeletons and endoskeletons and since they do not have a CELL WALL that gives them more mobility have been learning about plant cells and during this research i learned that even though the plant and animal cell are almost the same there is a few differences between them. How a plant cell has a CELL WALL, and CHLOROPLAST and animal cells don't have a CELL WALL because animal cells have other forms of support like exoskeletons and endoskeletons and since they don't have a CELL WALL they have more mobility for increased flexibility and advanced cell/tissue specialization. Animal cells dont need CHLOROPLAST cells in their bodys because since a animal cell does not undergo photosynthesis they do not need this cell in its body. The only reason a plant cell has a CHLOROPLAST is because they need it to absorb light and use it in conjunction with water and carbon dioxide so they can be able to produce sugars and then photosynthesis comes in and that is when it produces energy (ATP.) ATP means it is short for adenosine triphosphate; it is a high-energy molecule used for energy storage by organisms.
The one question I have is why wouldn't a plant cell need a Centrioles?
Railroadfan:
I'm just making a guess on the answer for your question. I think they look kind of like worms because they need to take that shape to be able to move around inside the body. Also their long, skinny shape could help them get into a part of the body where a fatter cell wouldn't have been able to go.
i am studying animal cells and i learned that animal cells dont have a cellwall also it has a double membrain.
what surprised me the most was the animal cell d.n.a is the same as all the anther cells in the body.
the thing a like about animak cells that they are the same thing like all the anther cells
something that i have been wondering have about we dindt have an cells in our body will we fell anything i our boby like if we get shot or something.
I am currently studying stem cells with a few other people. So far I have discovered that they have all the same organelles as any other animal cell, but they just haven't been specialized. This means that they are not a specific type of cell yet. For example cells in an animal's body such as blood cells or bone marrow cells have already been specialized, but a stem cell can turn into any cell that the body needs. For a question that I have, why don't the stem cells imediately become specialized when they contact other specialized cells?
I learned that cells can replace another cell without surgery.
What surprised me was that Stem cells can help Diobetes!
I know way more things then i did before. Ialways thought that cells were just another part of our bodys, And didnt really think there was much to learn about them.
I want to know why we didnt do this before, i mean like doctors and scientists.
(( I am studying PLANT CELLS)).
A question I have:
- If the plant is physically bigger, is the cell-wall bigger, and or stronger?
Something I learned, that surprised me:
- Plant cells remove excess carbon dioxide from the air! This means that they help us, to breathe.
Something I am interested in knowing more about:
-How is the "cell-wall" in a plant cell so strong?
Something I have learned:
- The reason that plants are green are because of the chloroplasts, a part of the cell, which contain chlorophyll.
I have learned that one of the differences between a regular cell and a cancer cell is that a cancer cell never stops reproducing and a cancer doesn’t obey signals from the rest of the cells. Also I learned that there are over two hundred different kinds of cancer cells. That surprised me because I never thought that there could be that many.
I am interested in knowing more about which part of the brain is cancer most likely to go or be.
I would like to know if your body could stop the cancer on its own and how quickly could the cancer cells can spread through your body.
(I STUDIED STEM CELLS)
I learned that stem cells are unspecialized cells. Also they replace any destroyed cell or body tissue.
What surprised me was probably finding out the amount of reasearch that is being done,in the future scientists are looking at stem cells to cure diseases.
Something that im interested in that i would like to reasearch more would probably be where did we get stem cells?
A question that I've had through this experiment would be: What would we do if we didnt have stem cells at all?
- chrissybrown08
Milkman:
i think that your further reasearch question was very interesting and i would also like to know more about plant cell structure.
idk345:
i thought that what you learned about cancer cells was interesting because i've heard that cancer and virus cells are hard to research.
Tonystewart:
wow i had no idea that bacteriophage was a virus, actually i didnt know what it was in the first place lol.
- Chrissybrown08
I've been studying animal cells and I was wondering how and why the Golgi Bodeis receive materials from the endoplasmic reticulum and send them to others parts of the cell? How and why do thet release materials outside the cell? The text book that I got this information from didn't make this very clear for me. I was pondering this for a while. Also I was wondering how Camillo Golgi found this out?
I was wondering when i look up animal cell images, they all look different? I was just wondering because when I type in animal cell images, they all look so different from each other. Some look like drawings (which aren't so complex), and some of them look like they've been created by a computer (which are complex looking).
hello there: I am also studding plant cells. I might be wrong but I think if a plant is bigger, there are just more cells. I don't think if the plant is bigger, the cell, or cell-wall is bigger or stronger.
paintballmonkey8: We would be alive if we didn't have any cells. If fact, we are cells. We not only wouldn't feel anything, we would be here right this very moment.
hello there!:
To answer your question on cancer cells, yes, some cancer cells are attracted to certain people. The cancer cells don't really choose, though. It would be a genetic thing.
stewie213:
I am guessing that plant cells don't need Centrioles because since Centrioles are involved in the division of the cell, plant cells might divide differently.
chrissybrown08:
If stem cells did not exist, humans and animals would not live.
Something I learned about viruses, the topic I'm doing my project on, is that some, like the T4-bacteriophage, are good for you. The T4-bacteriophage attacks the E. coli bacteria, a bacterium that is very dangerous to humans, and turns it into a virus factory. Then more T4-bacteriophage leaves the cell and attacks more E. coli.
Something that surprised me is that viruses can't take control of plant cells by themselves. The cell wall, which is on plant cells, is to thick. So, plant cells get attacked by viruses when, lets say, a animal with a virus eats part of a plant. The virus is transferred to the rest of the plant when some of the cell walls are broken by the animal's teeth.
Something that I want to know more about is how viruses evolved over millions years.
A question is, do viruses need oxygen to live? Could they live in space?
Comments:
For miley montana: To answer your question, I'm pretty sure I have an answer, stem cells, the way some plan to use them, is a controversial topic. Some want to use the stem cells from the babies that, when in early development, are aborted. This angers some because abortion it self angers many. The other side of the argument is that we shouldn't let these babies, who some say were never really alive, go to waste. There are places in grown humans where stem cells can be taken safely and securely. Unfortunately, there have never been many donors.
So in conclusion to this long winded answer, abortion hasn't become popular, or more used and perfected, since very recently, and using stem cells has only happened in the past decade.
For Tony stewart: I will attempt to give you my guess of what I think the answer to your question is. I believe that viruses, such as the T4-bacteriophage, have sensors somewhere on their "body" that tell the virus where the E. coli bacteria is. I think it may be something like echo location, which dolphins and bats use, where sound waves are sent out by the creature and they bounce off of objects sent back vibrations that differ with each object.
For Railroad Fan: To answer your question, I believe that some bacteria are worm shaped because it helps them move around.
I think it helps them get where they need to be to harm animals' bodies.
Through the recent research I’ve compiled, I have learned many characteristics and facts about bacteria. The thing that struck me was how such a small and strange cell that seems unlike us is surprisingly similar.
Despite the size of all living creatures on earth, I have learned that we all work the same way, no matter the size. Bacteria eats, grows, excretes and reproduces, synthesizes and responds to changes like us. Although a bacteria cell may seem like a basic and slow, squirmy glob from the outside, their anatomy is complex and extravagant.
Although we share all the same characteristics of life, bacteria cells perform each one differently than we do. Bacteria cells eat by engulfing food into their bodies, a bit different than eating through a mouth. They even reproduce like humans, except with a hollow pouch made of protein called the pili. They get rid of waste by pushing it out of their bodies.
In creating the glogster poster about bacteria, I learned a lot through the process. Not only have I gained more knowledge about my topic I have also learned how to use the glogster site and efficient methods of displaying information. I have a question that could be of great help to me, how many species of bacteria exist today?
While looking at models of bacteria, I have yet to match each organelle with the proper characteristic of life from the MRLSTRNGER acronym. If anyone could answer: what does one of the following bacteria parts relate to in MRLSTRNGER?
Nucleoid-
Ribosome-
Storage granules-
Endospore-
Capsule -
Cuter membrane-
Cell wall-
Periplasmic space-
Plasma membrane-
Piliflagella-
response to Chrissybrown08
Q-Stem cells are just unspecialized cellls that we have to replace dead cells. If we didn't have stem cells than it would be really hard to recover from injuries or maybe even impossible in some cases.
Response to Larularu1(7)2
You didn't include any questions that you had about cells and your response had some spelling and punctuation errors. Next time you should check your work more carefully and make sure you answered all of the questions that were asked. You should have also included the type of cell that you were studying because it would be easier for people to share their own imformation with you if they knew what kind of cell they should comment on.
Response for Milky Milk
Q-Why do all of the pictures of animal cells look different?
A-Most of the pictures probably look different because they are different kinds of animal cells. There are so many different types of animal cells like skin cells, blood cells, stem cells and a lot more different kinds of cells. If you just simply search "animal cells" a lot of different pictures will come up from all different kinds of cells.
Over the course of learning about cells I have discovered many things. First, if anyone has any idea where I can find out how a virus preforms MRLSTRNGER, I havn't found anything and I am at the point where I am going to rip my hair out. It is really frustrating. Please help.
hello there!:
I think that cancer cells are introduced to your body over a period of time, with a chemical or mutation. They thought my grandma died this way because she taught water areobics in a clorinated pool for over 30 years. The clorine slowly, for lack of a better word, attacked her lymphoids, thus she contracted lymphoid cancer, and died. Cancer is an extremely powerful disease.
jOoE is AwSeeM:
First, your name is too hard to copy.
Second, I belive every thing needs oxygen to live. Also, I think it is very cool that a plant gets a virus from the animal that eats it.
One Question for anyone who is doing stem cells: If you introduce stem cells to cancer, will the stem cells become cancer cells. Just putting that out there.
Thanks for the info, kr.td.23. Oh, and sorry about how hard it is to spell my name.
-jOoE is AwSeeM
PS I'm having a lot of trouble with virus and MR. L. STRANGER. You kind of have to have a broader veiw since viruses don't have organelles. Here's a site that I find helpful:
http://micro.magnet.fsu.edu/cells/virus.html
Milkman: The cells need all these parts because they are all important in their own way. They all have an important job to do.
jOoE is AwSeeM: Viruses don’t need oxygen because they don’t breathe. Most living things do but people are torn between viruses being a living thing so this is probably one of the reasons people think viruses are non-living.
Milky Milk: Maybe they all look different because they are from a different point of view or it could be really hard to model so they have to make it as close as possible but not exact. Also there might be different kinds of animal cells. There could be animal brain cells.
Thanks for your info, soccer123.
-jOoE is AwSeeM
Thank you for answering my question idk345.
purplemonkey to answer your question I will have to say that there is a total number of species of bacteria range from about 10 million to a billion.
To answer another question you had Purplemonkey is
what does one of the following bacteria parts relate to in MRLSTRNGER?
Endospore- This one relates to REPRODUCTION because it means (reproduction) "LIVING THINGS THAT MAKE COPIES OF THEMSELVES." Endospore relates to it because it means it forms spores that can resist to drought, high temperature and other environmental hazards. Once this hazard goes away the spores germinates to create a new population.
To answer your question jOoEisAwSeeM "Could viruses live in space?" Yes they can because Recently a Virus Named Gammima.AG was found on a Laptop issued to one of the NASA space astronauts which were taken to the ISS. The virus which was discovered waits on infected machines waiting to steal login names for popular online games. They also said that "its not the first time computer viruses had travelled into space."
Comments to:JOo is awesome
Your reflection was interesting and well said, as your comments were quite informative. Your choice of questions showed that you really are fascinated by your topic, letting you put enough thought into it that you can come up with such creative querries. As far as I'm concerned, viruses don't need oxygen to survive, yet lack the physical requirements to survive in space.
Comments to: soccer123
I enjoyed reading your reflection because it was short, interesting, and to the point. Your questions made me think until reaching an answer. From what I have heard, the rate cancer cells can engulf a human varies with the type of cancer, the location of the tumor and the health and strength of the immune system.
Comments to: milkman
Your reflection was easy and enjoyable to read. The fact that you divided your writing into parts made anyone who sees it want to read. The answer to your question is hard to explain. Think of a human body, think why do we need all our parts? That must make it clearer and easier to relate to. Imagine a human without a brain, stomach, liver ect, What would you think would happen to the person? Each part works in unison with the rest of the body. like a sports team, if one is hindered, the entire team will suffer.
Comments:
idk345: I think that’s kind of cool that cancer cells don’t stop reproducing, but I’m not surprised. I m not surprised because otherwise how would it spread so fast.
I’ve never thought about where brain cancer affects the brain. that’s a good question. over all I thin it was written well.
railroadfan: I don’t agree that bacteria cells should look like viruses. I think even though you get sick from bacteria and a cold can turn into a virus and all that they still shouldn't look exactly the same. Over all I think it was a nice short little thing about what you think.
miley montana: I originally wanted to research on stem cells but I decided on bacteria. I’m not surprised they don’t need surgery to replace each other cells can do a lot of things on there own. I liked your layout and it was well written
Ummm...thanks Stewie213, but that wasn't what I was asking. I was asking about natrual viruses, not the computer ones. But that was a cool peice of info.
