One part of the Cell Theory says that the cell is the smallest _____________________.
Unit of life.
200
What is the main ingredient in cells?

300
Which macromolecule is made of long chains of amino acids? Hint: It's job is to do "stuff" in the cell.
Proteins.
300
Which organelle makes proteins?
Ribosome.
300
Sometimes cells need help to move things across the membrane. They get help from transport proteins. What are the two kinds of transport proteins?
Carrier proteins and channel proteins.
300
Another part of the Call Theory says that all cells come from __________________ cells.
Pre-existing.
300
What is the job of the cytoplasm?
To fill the space in the cell and hold organelles in place.
400
Which macromolecule does not dissolve in water? Hint: It's job is to help make the cell waterproof.

What is one difference between a cell membrane and a cell wall?
Cell membranes are flexible and protect animal cells. Cell walls are stiff and protect plant cells.
