What is the function of the cell wall in a plant cell?

• A strong layer of cellulose that helps to hold the cell in shape

• Where the plant makes its food

• Controls the activities of the cell

• A clear jelly where chemical reactions happen

What is the function of the nucleus in a plant cell?

• Where energy is released from food

• A thin layer around the outside of the cell that controls what goes into and out of the cell
