Question

Which among the following statements are correct regarding vacuoles?

• A. Vacuoles are not membrane bound.
• B. Vacuoles are present only in plant cells.
• C. Vacuoles occupy 50-90% of the cell volume in plant cells.
• D. In amoeba, food vacuoles digests food.

Answer 1

Answer: (C), (D)

In amoeba, food vacuoles digests food.

• Vacuoles are single-membrane bound, fluid filled spaces. They are present in the cytoplasm of the cell.
• Vacuoles are present in both plant and animal cell. In animal cells they are smaller in size and lesser in number.
• Plant cells on the other hand have one large vacuole which may occupy 50-90% of the cell volume.
• In amoeba, the food vacuole contains the food items which the organism consumes. In some unicellular organisms, specialised vacuoles also play important role in expelling excess water and some wastes from the cell.
