Q. (a) What role vacuoles play in a typical plant cell ?

(b) What will happen if Golgi Apparatus is removed from the cell ?

(c) Why the inner membrane of mitochondria deeply folded ?

Ans. (a)

Vacuoles are the storage sacs for solid or liquid contents.
In plant cells, vacuoles are full of cell sap and provide turgidity and rigidity to the cell.
Many substances which are important in the life of the plant cell are stored in vacuoles. These include amino acids, sugars, various organic acids and some proteins.

(b) The following things may happen in the cell if there was no golgi apparatus :

There will be effect on the packaging and dispatching of different types of proteins to various targets, inside and outside the cell.
The products of the cell cannot be stored and modified further.
The formation of complex sugars from simple sugars cannot take place.
The formation of lysosomes will be affected. This may cause accumulation of worn out and dead organelles within the cell which may lead to cell death.

(c) The deeply folded inner membrane of mitochondria creates a large surface area for ATP – generating chemical reactions.
