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!

The protein walks and strains and guids the vacoule to the membraian that runs the whole cell.
I didnt know that there were like tiny boats that float on a water substance.
why does the protein have legs!!!
What cell are you talking about chikachikaboomboom567?
I learned that there are different kinds of cancer cells. The breast cancer cell looks the coolest though.
So far the coolest thing I have learned is that only bacteria and plant cells have a cell wall. I also find it amazing how much plant and animal cells have in common.
Though I am wondering what do cancer cells look like? How do they target the piece of the body? Is there different cancer cells that only go to certain parts of the body?
Joebeeb the type of cell in the video wasn't either a plant cell or a bacteria. Here's the link to the video... http://www.youtube.com/watch?v=fZZ3DD_tV9k
Dear chikachikaboomboom567
The reason the protien has legs is it is a motor protien used for transportation.
Some things I have learned about bacteria are that they have a cell wall and they reproduce asexually. I was surprised that the ribosomes were dotted throughout the cell membrane, but in the animal cell the ribosomes were surrounding the Rough ER. I am interested in learning more about each part of the bacteria and what they do. One question I still have is which part of the bacteria is responsible for reproduction?
Pretty Pink Prince – If you want to know what cancer cells look like, just type it into Google images. I found some good pictures there, but there were so many different ones I couldn’t post all of them.
Four facts I’ve learned about a plant cell:
• Chloroplasts contain chlorophyll, which are responsible for the plant’s green color.
• Plant cells have a cell wall unlike an animal cell. The cell wall is a rigid layer that surrounds the cell membrane.
• A double membrane encloses the nucleus of a plant cell.
• The cytoskeleton plays a very important role in a plant cell. It holds the shape.
Something that surprised me:
• The cytoskeleton (even though it is the structure to the cell) can move and adjust to the cell’s new shape when it reforms.
Something I am interested in knowing about:
• I would like to find out more about the centrosome. If you find any interesting or helpful facts about the centrosome, please comment.
Questions I have about a plant cell:
• What is the cytoskeleton made out of? I’m interested because it can hold the plant cell’s structure but it can reform and adjust to the cell’s new structure.
To answer your question (what does a cancer cell look like?) “Pretty Pink Prince”. Here’s a link to what I think will answer your question….

Also, to anyone who is interested in plant cells and still don’t understand the process of photosynthesis, here’s a link to an interesting youtube video…

While studying animal cells I have found that there are many interesting things about them. Unlike plant cells that have a cell wall, animal cells have a cell membrane which is used to create a barrier from the environment around the cell. Also, the cells energy is produced in small rod shaped organelles called mitochondria.
I am interested on learning more about the cell membrane. I am wondering if it changes it's shape to adjust to the environment around it. If you find any information about it, please let me know.
I am also wondering if animal cells have any locomotion. Please let me know if you find anything.
Pretty pink prince, I have found a good link that might lead to the answer of your question.

Ryley Clyde, Here is a link that might hold the answer to your question.

Bandcamp, this is a link that might have the answer to your question.

I am learning about bacteria cells. I learned that bacteria cells come in three main shapes (spherical, rod and spiral. I was surprised that bacteria cells have no nucleus. I want to learn more about how the parts fit into the MRLSTRNGER and what some of the parts do. I am kind of confused on which organelle acts as reproduction because when we were researching, we found two that both sounded like reproduction. I also want to know if there are any other shapes that bacteria cells can be besides the three that I mentioned above.
Ryley Clyde- One thing that I found that was in the cytoskeleton is protein.
Joebeeb- Is there a different kind of cancer cell for each kind of cancer?
Pretty pink prince- I was wondering the same things. Do you think that maybe different kinds of cancer cells go to different parts of your body?
Ajax555 – I think the answer to your second question would be no, but I found a picture on Google that showed what looked like variations on the shapes that you already had.

Ryley Clyde – The answer to your question is the cytoskeleton is made of F-actin stress fibers.
STEM CELLS
I learned that Most cells that form during fertilization can form into any type of cell in the human body.
What surprised me was that cells that can be specialized can only be called stem cells.
Does a stem cell form the same as any other cell like; plant cells, viruses, bacteria, animal cells or any others?
Dear Ryle Clyde I found ou that the cytoskeleton is made of alpha tubulin and beta tubulin aswell as protien.
About cells, I was really surprised how many big changes and differences a microscopic thing can do. Also in the cell, the parts of the cell, like the nucleus, and the cell wall, those must be even smaller.
Two questions that I have are, what powers the nucleus to keep running and running? And what does a real 3-d cell look like?
bandcamp - About your question on what part of a bacteria cell reproduces?, try typing it in on wikipedia. They almost always have the answer.
curlylocks123 - What can a stem cell do that no other cell can?
What do they have in common with other cells?
ajax555 - Your question on how do cells reproduce, it seems a lot of people ask that question. And I wish I had the answer for you. But I looked on a bunch of different sites, and I couldn't find it. Or at least it was not that easy for me to find. But maybe the answer is in a textbook in Mr. Ardito's classroom.
I learned that cancer spreads by building up then it breaks off and spreads by going threw the blood cells and that the cancer is named after the place where it starts.
It surprised me that cancer are just cells that don’t die regular cells die but these don’t so that’s how it’s basically made.
I’m interested in knowing more about what makes the cells not die what happens to make them be different or does it just happen like that
I have a question about if cancer cells can be interacted with other cells than regular cells
Ryley clyde
you had really nice work I didn’t see anything wrong with yours
dadrumma3
nice video I think your questions were worth looking into
Ajax555 I think the answer to the second question is no
I was surprised that a cell so small and microscopic that so much can function and work inside it.
I learned that all virus cells are different for each virus.
1. I've learned that bacteria and plant cells both have cell walls
2. I was surprised that cells can actually explode in a hypotonic solution. (I learned this from my sister.)
3. I wanted to learn more about how cells explode in a hypotonic solution.
4. I wanted to know what is an example of a hypotonic solution.
Dear Curlylocks,
what you said was indeed true. I believe that if I did not have any background information about Stem Cells, that would not have compleatly cleared it up. I have a question: what do stem cells have in common with other cells? Are they even close?
STEM CELLS:
I have found out that scientists are saying that Stem Cells can cure any disease.They have not offically declaired it true, but they are figuring out ways to prove it.
Dear Pretty Pink Prine,
I was wondering the same exact thing, only for Stem Cells and Cancer Cells. Also, I would further like to reaserch plant cells, becasue a lot of people I consult with say that they are very fascinating.
I'm learning about Stem cells. A cool thing about stem cells is that they start without anywhere to go. When they get a job to do they go right to it and become one of that certain type of cell.
I have a question about Stem cells: can they form into all sorts of cells or just in the human body?
Here is a very helpful (yet fun) website about Stem Cells:

A few things that I learned about cells is that they reproduce asexually.
bandcamp the part of the bacteria cell that is responsible for reproduction is the sex pili
