**EQ1 - Why is the cell considered the basic unit of all life?** =Angela= The cell is considered the basic unit of life because all living things are made up of cells. Also, cells are able to perform everything that we do. They are what make us be able to move around, do things, and live our life. Without cells, we wouldn’t be living, because they are what make us be able to do things. So, the cell is considered the basic unit of life because it is what makes us be able to live.

Mrs. B: Can cells do EVERYTHING that we can?

=David= Cells are considered as the basic unit of life because they make up an organism. Cells work in groups and forms tissues->organs->organ system then finally to an organism. Most cells work in a group to do a certain job, if one group of cells that does a certain job for instance a white blood cell that kills intruders dies, we will be no longer immune to the intruders and it can cause diseases etc. Without cells, the organism will basically be malfunctioning. So cells are an important aspect of life that gives us abilities to do things and live.

Mrs. B: What are some diseases that might affect cells in the way that David is talking about?

Back To Top =Ryan= All life is made of cells, without cells we wouldn't work the way we would today. Since all life is made from cells, all cells are living. Cells aren't always working alone, usually cells work in groups which later on forms tissues, then organs, after that it is the organ system then it would end up as an organism. Without one cell in a group you probaly wouldn't function right, or the way you should. Image "Large blood cells" Link: http://www.fi.edu/learn/heart/blood/images/large_white-cells.jpg

Mrs. B: Would the loss of one cell affect the organism? JX : I liked the way you explained why cells are important to our lives. I think it is pretty clear and explains it well. David: I like you being specific in terms of that cells work in groups and builds up to be an organism ㄴ My opinion on Mrs B's Q: I think I've heard that brain cells are nearly impossible to gain back...Im not sure of just a few loss but I think losing alot of cells is a problem (such as loss of white blood cells can cause leukemia...).

=JX= Cells are considered the basic units of life because all life is made of them. They work together in groups to create tissues, then organs, then systems, then organisms. Without cells, the smallest thing that is considered living, we wouldn't exist. The cells work together in a certain way to make sure everything is working how it should work. For example, some cells work together to make a tissue (brain tissue). Enough of the brain tissue will make a brain (organ). The brain is part of the nervous system, which is needed in the human body. Image: Red Blood Cells Link: http://sciencemuseum.org/uk

Mrs. B: Can you give an example? Ryan: Yeah, I agree with you, if cells didnt exsist nor will we.

The reason cells are considered the basic unit of life is because any living thing is made up of cells and they control how all living things live. Cells are what make up our tissue which makes up our organs. each organ plays a different part in running activities needed to survive. Cells are the smallest that is able to perform such advanced tasks. Cells usually work in groups to control different things. This explains why cells are considered the basic unit of life.

Mrs. B: "Cells are the smallest that is able to perform such advanced tasks." What advanced tasks are we talking about? Let's try to list four REALLY important processes to the cell...

== Cells are the basic unit of life because every thing is made of cells. Cells make up tissue which makes up organs which makes an organ system which makes an organism. Cells work in groups to perform tasks. Some organisms are unicellular like organisms called bacteria. ==

Mrs. B: Is __everything__ made of cells? Is a table? A rock? A piece of dust?

Cells are the basic unit of life because everthing is composed of cells. The cells work together to create tissues, the tissues work together to make organs, and organs work together to form organ systems which form organisms. Without cells, there wouldn't be organisms. All life is made from cells. red blood cells Mrs. B: OK folks, we need to get away from the "cell to tissue to organ" answer and add some fresh details..... Josephine: I like your picture. What is that white thing in the middle of the red blood cells? Back To Top  **Mathieu** = = Cells are the basic unit of life because they work together to make tissues, tissues to organs, and organs to organ systems. Without these little cells I don't thing we would even be here. The cells are life. Without life theres nothing. www.flickr.com/photos/34754790@N00/19191446

Mrs. B: See comment for Louise...and you need to be more thoughtful in your response.

back to top =Brandon= Cells are considered the basic unit of life because everything on and in us is made up of cells. Without cells we wouldn't be living and neither would any animals. Cells is what enables us to do things. Without cells we also wouldn't have any organs. Our organs also play an important part in our body. So without organs there would be no cells, so there would be no life. http://www.3dscience.com/catalog/images/cells_rbcs_web_thumb.jpg Image: Red blood cells

Harry (T.): Wtf? Dude. Cells MAKE organs. Organs don't make cells. "So without organs there would be no cells." Harry (T.): Hm. I don't know. Maybe coral. No. That's not right. Mrs. B: Do any organisms exist that don't have organs? Can anyone find an example of one? Josephine: Bacterias don't have organs Back to top

=Harry= Cells are considered the basic unit of life because the cells make up our blood, our organs, and even our hair! These little beings are what make us able to live our life the way we are doing now. Cells work hard to keep us alive; in return, we must keep them healthy (by eating lots and lots of VEGETAbles) and active.

Mrs. B: Look at the requirements page or ask Ms. DeCardy or myself. Harry, I really liked how you used your own words in the answer. Nice job! Ryan: Yes, by eating a lot of VEGETAables, Harry. Jonathan: Very good answer (unique too!). Yes, we must try to keep them healthy too! Back to top

=**Josephine**= Cells are considered the basic unit of life because cells make up every living things. (including vegetables, plants, animals) They made up our organs, muscles, skin and anything that's in your body. Cells and cells make tissues, tissues and tissues make organs, organs and organs make organ systems, and organ systems make up an organism, which is us. Credit to Josephine

Angela: Wow! I love your picture! It's drawn really well, and it helps me understand the whole "cells make up tissues which make up organ which make up systems which make up organisms."

Mathieu: I really like the picture because it really shows how the cells develop and become big things like systems. Josephine: : D [|Back to top]

=Paige= Cells are considered the basic unit of life because every living thing is made up of cells, such as animals, plants, humans, ext.. Without cells, we would not exist. Cells make up tissues, which make up organs, which make up systems, which make up organisms. Cell have different jobs, some cells keep bad stuff from entering our body.

=Hannah=

Cells are considered the basic unit of life because they are what make up life and all living things. Cells give us ability to function. Without them, we would not be able to live. Cells make up tissue, tissue works together to make organs, which makes organ systems, which finally ends with organisms. Cells create life.
