Solution

The correct options are
A They are more in number in animal cells.
B They can occupy 90% of the plant cell's volume.
C The membrane of the vacuole is called tonoplast.
Vacuoles are organelles which help in storage of salt, sugar, amino acids etc. Animal cells have more vacuoles than plant cells. Vacuoles in animal cells are smaller in size than the vacuoles in plant cells. Vacuoles in plant cells are very large and can occupy upto 90% of the volume of the cell. The vacuole is surrounded by a membrane called tonoplast.
