Plant cells have a large central vacuole that takes up most of the cell’s space, and animal cells have many smaller vacuoles.
Explanation:
Plant cells are characterized by the presence of large vacuoles present in the center of the cell. The vacuole is large enough to occupy as much as 90% volume of the plant cell.
On the other hand, animal cells have a centrally located nucleus. They do not have large vacuole. Rather, animal cells have many smaller vacuoles that are present near the periphery of the cell.
