Answer 1

Answer: (A), (B), (C)

The correct options are
A They are fluid-filled sac like structures.
B They are present in both plant cells and animal cells.
C They are involved in expelling excess water and some wastes.

• Vacuoles are present in both plant and animal cells. They are small sized in animal cells, while plant cells have very large vacuoles.
• In some unicellular organisms, specialised vacuoles play important roles in expelling excess water and some wastes from the cell.
