Question

Column I list a few activities of living organisms and column II the activity of cells related to them. Match the items in the two columns.

Column I (Activity of organism)	Column II (Activity of cells)
(i) Repair	(a) Contractility of cells
(ii) Cooling of body	(b) Cells devour germs
(iii) Movement	(c) Cell division
(iv) Protection from diseases	(d) Gland cells give out sweat for evaporation

Accepted Answer

(i) -→ (c)

Cell division helps to produce new cells. This helps to repair the worn and torn cells and also helps in the regeneration of cells.

(ii) -→ (d)

Sweat glands present in our body releases sweat out of the body for evaporation then, the body cools down.

(iii) -→ (a)

The actin cytoskeleton plays a central role in cell contractility. This helps in the movement of an organism.

(iv) -→ (b)

White blood cells are amoeboid and it protects the body from the diseases by engulfing foreign particles and germs.
