Question

Two reason for which plant cell have large vacuoles

Answer 1

To store food and water.They are equipped with a large vacuole in comparison to animal cells since the plants are immobile to gin nutrition from surrounding and they need to store as much food they can(an evolutionary feature to support survival).

To hold turgor pressure across the cell wall


hope this helps you

Answer 2

Vacoules are fluid filled membrane bound clear spaces in the cytoplasm.

They are filled with water and a variety of substances like minerals, sugars , carbohydrates, organic acids , pigments and metabolic wastes in solution .

The membrane of the vacoule is called tonoplast and the liquid they contain is cell sap .

In mature plant cells , a large vacuole occupies most of the central part of cell .

This pushes the nucleus and other cell organelles to the periphery of the cell . These vacoules are called sap vacoules .

In animal cells , the vacoules are generally absent . But if they are present then , they are much smaller.

Food vacoules and contractile vacoules occur in unicellular animals such as Amoeba and paramecium .

Functions of vacoules :

• They keep the cells turgid and provide rigidity and support.

• They store food material and waste products .

• They help in maintaining the water balance and in extraction .
