Transcript of Cells

Before we can understand cells, lets take a look at what we are made from.
There are four main molecules that comprise all organic compounds.
Carbohydrates
Lipids
Proteins
Nucleic Acids
Keep in mind:

everything is made out of a combination of elements, held together by various bonds.



Great! So now we know what everything is primarily made from, what's next?
Now, we need to break down the cell itself and see how it works as a single unit of an extremely large system. My expectation is that you will be able to label all the cell organelles and explain the function of each within the cell.
GOAL!
My hope is that you now have a better understanding of what cells do and why they are important. Next, we are going to learn how a cell is able to make all of these awesome macromolecules to help make you... you!
Remember: your homework: Read ch. 22. Complete pages 488-490. Review #1-10, Think/Explain #1-9, Think/Solve, Multiple Choice #1-10. Due 10/08. Your paper is due Tuesday!
Cells
Thank you!

A video tour of an animal cell.
So now we know the parts, let's summarize what the main function of a cell is.
You need to identify
three
different things that a cell does



Now, I want you to explain
why
you think it preforms these tasks.
How it all works.
I want to draw your attention to how a cell works individually to help you understand what a trillion cells do as a whole. Let's think of your skin... it's the largest organ your body has. It is made up of trillions of cells and all of your skin cells are similar and are able to perform specific functions that your skin needs to have, that other organs in your body might not need.
One cell works with many cells to form
tissue
.

(Epidermis)
Tissues work with other tissues to create
organs
.
(Like your skin)
Organs work with other organs to perform vital functions to maintain your characteristics of life that you have to have in order to still be an organism.

(Your skin works with your nerves to help you shiver when you get cold to try to warm you up.)
Keep in mind:
there are many different types of cells and we are going to learn about more than one!
