• Cell wall

• Chloroplast

• Vacuole

• Ribosome

Cell wall ( plant cell only)

• fully permeable

• thick and rigid

• protects the cell

• help plants hold their shape, even when they're thirsty.

​cell wall

Cell membrane (animal cells and plant cells )

• made up of phospholipids and proteins

• thin and flexible

• controls the movement of substances into and out of the cell

​cell membrane

Multiple Choice

Which of the following is not a function of the cell membrane?

• Regulate cell growth and division

• Protect the cell from its surroundings
