Question

Match the following concerning essential elements and their functions in plants:

	Column-I		Column-II
(a)	Iron	(i)	Photolysis of water
(b)	Zinc	(ii)	Pollen germination
(c)	Boron	(iii)	Required for chlorophyll biosynthesis
(d)	Manganese	(iv)	IAA biosynthesis

• A. (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)
• B. (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)
• C. (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)
• D. (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)

Answer 1

The correct option is A (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)

Iron plays an important role in the biogenesis of chlorophyll. Deficiency of iron has been found to be associated with loss of chlorophyll in the plants along with decline in photosynthetic abilities.

Zinc plays an important role in IAA biosynthesis.

Boron has a role to play in pollen germination at optimal concentration.

Manganese plays an important role in mediating photolysis of water, which is an important step in photosynthesis.
