Question

why is plant vauole large whereas the animal cell vacuole is small.

Answer 1

Plants have single large vacuole as compared to the animals which have many small vacuoles due to the following reasons:

Storage: Plants form the base of the food chain. They are capable of converting inorganic matter to organic matter. To store these inorganic ions they are provided with the large vacuoles.

Moreover, plants cannot move from one place to another. So, it is very essential for plants to be able to store extra nutrients when nutrients may not be available.

Growth: Plant cells grow by swelling. They are provided with a rigid cell wall. To make this wall expand, plant cells fill their vacuoles to exert pressure from inside.
