A cell wall is found in plants, algae, fungi, & most bacteria.

7. CELL MEMBRANE Outer covering, protective layer around ALL cells
For cells with cell walls,the cell membrane is inside the cell wall
Allows food, oxygen, & water into the cell & waste products out of the cell.

8. CYTOPLASM gelatin-like inside cell membrane constantly flows
aka protoplasm

9. NUCLEUS Directs all cell activities
Contains instructions for everything the cell does
