Question

what are vacuoles???​

Answer 1

A vacuole is a membrane-bound organelle which is present in all plant and fungal cells and some protist, animal and bacterial cells.

Answer 2

Answer :-

Vacuoles are the structures inside the cells which mainly help in the storage and transport of necessary substances such as food, enzymes,ions,etc.

Functions :-

• They play a great role in the facilitation of the transport of ions against the concentration gradient of the cell in which they are situated.

• In some cases,they protect cells from harmful radiations ( Eg: Gas vacuoles protect Prokaryotic cells from UV-radiations).

Extra Information :-

• Vacuoles are mostly absent in animal cells but, they occupy about 90 percent of the space in plant cells.

• Vacuoles are single membrane structures.

• The membranes of vacuoles are made up of "Tonoplast" and are semi-permeable in nature.
