EQ1 - Why is the cell considered the basic unit of all life?

Luke
Cells are the basic unit of all living things because cells make up everything that our body needs to survive such as tissues. A slight change in the cell arrangement can change the arrangements of tissues, and this would cause the tissues to change the arrangement of organs and our system, and who knows, I might not even be able to be here typing out this respond just because of that little change in the cell that changed everything. The same goes for other animal cells and plants cells, a slight rearrangement in a plant cell might cause the plant to change color or make it's appearance change. To make a long story short, cells are just like traffic lights. Traffic lights might not seem like the most important thing on earth but imagine life on earth without them... Picture of a elodea plant cell. Rachel L: I like how you gave an example like the traffic lights.

=J-Ren= I believe that the cell is the basic unit of life as it’s what makes us. Cells make tissue, tissue makes organs, organs make systems and systems make animals which we humans are. Also if the cell is slightly altered it can change the way the organism works or looks. Cells are in a way like lego blocks. We’re built with loads of them and it takes all the cells to make what we are and if a certain thing is changed in the lego creation like pieces are removed or colours are changed the creation would look very different. PIcture of lego in a way this is how cells work

Mrs. B: I like your analogy to legos. Each lego is a building block for some structure, just as cells are building blocks for organisms. Can organisms lose cells without changing the creation/look/being of the organism? Who can give an example?

Emilie: I agree with Mrs. B, the lego analogy is really good!! I wish I thought of it :) I like how you mentioned how cells make tissues, etc.

Royce: Legos are radical, I think its awesome how you did that whole cell to tissue etc. thing =Zachary=

The cell is the basic unit of life because, it controls everything. A slight change in how it is made can effect the entire system of tissues and organisims. That is why plant and animal cells look very different. We also depend on our cells to give us life, to walk, to talk or even move. Without them, we wouldn't be here. It is like a simple equation cells=life. Every living thing always originates and from a cell and that is the basic unit of life.

Got from website: www.flickr.com/photos/45359107@N00/3111823929 Back to Top =Jonathan= The cell is the basic unit of life as it is the smallest unit that can carry out what a living organism needs. The cell comes in different shapes, sizes and also have unique different in built "add ons" which help each cell do its job. Which is why even though all living things are all made of cells, all of them are different. A cell also already contains its own "organs" which controls the cells, enabling the cells to aso control and be part of living things. Organisms are either unicellular or multicellular, which again explains that all living things, no matter how big or small, are made of cells!

Mrs. B That's great, Jonathon! We will actually be looking in detail at some of those "organs" that perform specific tasks for the cell that are extremely important for the cell to function and for life on Earth. Can you guess what any of those processes are?

Zachary Wow. I didn't know that the cell can just live on it's own except for bacteria. I never knew it contained its own organs to live.

Mrs. B: When we say "organ" as being part of a cell, we are really talking about organelles like nucleus, chloroplast, etc.

=Jeff= The cell is the basic unit of life as it is able to perform all the activities that a living organism needs. Each cell is a different size and come in diffferent types, specialized for each task. All cells have organelles, which make it able to survive and function. Each cell has the identical DNA to the organism it is a part of. The cells come together to create tissues, the tissues create organs, organs create systems, and systems create organisms.

Anthony Wow. Cells have organs!

Back to Top =Belle= The cell is the basic unit of life because every living organism comes from another organism, as cells come from other cells. So this tells us that every organism is made of cells. Cells can be in different shapes and function differently also. Different cells make different things. For example, different cells make plants and different cells make animals. A little change in the cells can affect the organism.

=**Anthony**= The cell is the basic unit of life because it composes every living thing in the world. Without cells there would be no plants, animals or bacteria. Each cell has its unique size, shape and job. A group of cells form tissues, a group of tissues form organs, organs create the organ system and last it creates organisms. So without cells everything would be dead. In conclusion the cell is the basic unit of life.

= = = = = = = = =Back to Top= = = = = =Connie= The cell is considered the basic unit of life because it makes up every existing organism. Every cell comes from another existing cell. For example, humans are made up of billions of cells, working together to form tissues that work together to form organs that work together to form organ systems that work together to form us. Each cell we have carries out a job needed for us to survive. Below is a picture of plant cells viewed under a microscope.

=Rachel C= The cell is the basic unit of life because everything is made out of cell. In order to form a living thing in the world, you'll need organisms to have it function properly, and in order to have a organism form, you'll need cells. Cells come in different shapes and sizes, and because every cell is different from one another, a tiny change in cells can cause an organism to function differently, and which causes the life-form to act differently. picture : http://www.flickr.com/photos/pong/13107953/

Rachel L: I like how you said cells come in different shapes and sizes since the cells are different from another. :D

=Ryan= A cell is a basic unit of life because all plants and animals have cells and are made out of them. They all come in different sizes and they all act separately. Cells allow us to function and live. They are the building blocks of our bodies and other organisms. all these cells come together forming our tissue, organs and organ system. therefore cells are vital for our lives.

Kate Really great response, Ryan. I especially like how you named out all the parts that cells make up (tissue, organs, etc.) Back to Top

=Kate= The cell is the basic unit of life because they are what make up all plants and animals. They are the smallest unit of a living organism, and can come in different sizes and shapes. Cells can act both on their own or together (unicellular and multicellular). They are what allow us to function and live, and they build up our bodies as well as other living creatures. Cells come together to form different organs in our bodies which work together on a specific job, A single change in the cells can affect the entire organism. ** Image: 'Animal Cell' http://www.flickr.com/photos/cooljerk/285390364/

Connie Wow, Kate. Good answer! I also really like your picture. It would be nice if you could enlarge it, so we could see the labels. I especially like how you mentioned that cells can act both on their own or together (unicellular and multicellular).

BelleHey kate i really like your picture! It's pretty cool since you can see where everything is and all that. Back to Top

=Emilie= Cells are the basic units of life because all organisms are made of them. Cells have different functions and compositions depending on the organisms needs. Cells build into tissues, which then build into organs, which then build into organ systems, which then build into an organism. Some organisms have only one cell, such as bacteria. Without cells we would not be able to live. [|Click here for picture] == Back to Top

=Royce= Someone must have deleted my earlier post. But cells are the basic unit of life, since that they are each similar to a dwarfed organism. They can either be prokaryotes of eukaryotes. Cells do their specific or widespread jobs to ensure that the organism's body works successfully, and allows the organism to thrive and operate Cells->Tissue->Organs->Organ Systems->Organisms Image: '[|Plant cells]' www.flickr.com/photos/34745138@N00/2549187990 Back to Top =Ethan= I think that the cell is considered the basic unit of all life because the first organisms were just one cell. Also, cells only come from other cells. if there weren't any cells, than there wouldn't be any of the parts of organisms that cells make up, which is most of the organism. If there were no cells, than there would be no organisms. 'animal cell' http://www.flickr.com/photos/cooljerk/285390364 Back to Top

=Rachel L.=

Cells are considered the basic unit of life because they make up plants and animals, also the smallest unit. Every cells comes from existing cells/other cells and they are unicellular and also multicellular. They can also be prokaryotes and eukaryotes. We are made out of cells, which makes up tissues, then organs, then organ system, then organism. Their are million bits of cells that make up one of us humans, also there are a lot of different kinds of cells. Each cells have different kinds of jobs that they need to do and without cells we wouldn't be able to function properly or neight living here in this planet right now. Below is a picture of an animal cell.
