AnswEr:

Vacuoles :

• It is a membrane bound organelle present in the cell.

• It's membrane is known as tonoplast.

• Tonoplast is actually a selectively permeable membrane i.e allow only selected material to in and out of the cell.

• Vacuole is having more amount of ionic concentration than cytoplasm, so it helps in osmoregulation.

• Number of vacuole is less in plant cell as larger and central vacuoles are present in it.

• Whereas in animal cell, number of vacuole is more and size is small.
