What is the function of the cell nucleus found in both plant and animal cells?

• to produce energy

• contains DNA

• to remove waste products

• to allow molecules to enter the cell

Chloroplasts in plant cells allow the plant to perform a function that animal cells cannot do.  What is the main function of the chloroplasts found in plant cells?

• to absorb light energy and manufacture food
• to remove waste materials by active transport
• to manufacture chemical energy from food
• to control the shape of the cell
