What is cell theory?
1. All living things are made up of cells. 2. The cell is the basic unit of structure and function. 3. Cells come only from other living things.

What does the cell membrane do?
-Protects the inside of the cell -Supports and gives the cell its shape -Controls the movement of materials into and out of a cell
500
What do the golgi bodies do?
Receives proteins from the endoplasmic reticulum, packages the proteins, and delivers the proteins to other parts of the cell.

Describe how vacuoles differ between plants and animals.
Plant cells have only one or two very large vacuoles. Animal cells may have many small vacuoles.
