Answer 2

Answer:

vacuoles are bounded by a membrane called tonoplast​.

Function:

》Tonoplast provides protection to the cell.

》It separates the contents of vacuole from the cell's cytoplasm.

》It is a semi-permeable membrane which regulates the movement of ions in and out of the cell.

》It maintains the acidic nature of the vacuole.

》It transports small amount of solutes and salts with the help of numerous proteins found in tonoplast.

The tonoplast is also called as the vacuolar membrane, and it is a cytoplasmic membrane that surrounds a vacuole, thus separating the vacuolar contents from the cytoplasm of the cell.
