Answer: C. Vacuoles are larger in plant cells than in animal cells.
Vacuoles are storage organelles that are found in both animal and plant cells. They store food or any other forms of nutrients, they also store waste products so as to protect the contamination of the cell environment. These waste products are sent out of the cell via vacuoles.
