Match column-I with column-II and choose the correct option.
Column-IColumn-II
A. TonoplastI. Contain digestive enzyme
B. Contractile vacuoleII. Store metabolic gases
C. Food vacuoleIII. Excretion
D. Air vacuoleIV. Transport of ions in plants

A. A IV; B III; C I; D II

B. A II; B III; C IV; D I

C. A IV; B II; C III; D I

D. A I; B III; C II; D IV

Correct Answer :

A. A IV; B III; C I; D II


Tonoplast is a membrane separating a vacoule from the surrounding cytoplasm in a plant cell. It controls ionic movement in and around the cell. Contractile vacuole is a sub-cellular structure found in unicellular algae. It absorbs excess water and wastes from a microorganisms cell and excretes them into the environment. Food vaculole is a membrane-unclosed cell vacuole with a digestive function. It contains material taken up in by the process of phagocytosis. Air vacuole is a small cavity or space in the tissues. It stores metabolic gases.
