B. Only animal cells contain vacuoles.

C. Vacuoles are larger in plant cells than in animal cells.

D. Vacuoles are larger in animal cells than in plant cells.

Answer: C. Vacuoles are larger in plant cells than in animal cells.

Vacuoles are organelles found in cells of plants and fungi. It is also found in some cells of bacteria, protists, and animals. In plant and fungal cells, vacuoles have higher prominence than in animal bacterial cells. The primary function of vacuoles is for osmoregulation and homeostasis. In plant cells, the vacuole also helps in supporting structures like flowers and leaves. In other words the vacuole helps the plant stay upright. With this, plant vacuoles are the largest due to their more complex function. Also, vacuoles in plant cells can occupy as much as 90% of the cell volume.
