9. What is this cell part and what does this cell part do?
It is the mitochondria and it makes energy for the cell

10. Why do animal cells have more mitochondria than plant cells?
They use more energy because they move.

11. Why is the vacuole larger in a plant cell ?
They have to store their water when it
Rains. We can refill ours when we drink.

It is stiff and thick, so the plant can stand up.
