Question

Match List-I with List-II and select the correct answer using the codes given below:

List-I (Root type)	List-II (Function)
(a) Carrot	(i) anchorage
(b) Stilt root	(ii) load-bearing
(c) Pneumatophores	(iii) store food
(d) Prop roots	(iv) respiration

1. (a) - (iii), (b) - (iv), (c) -(i), (d) - (ii)
2. (a) - (i), (b) - (ii), (c) -(iv), (d) - (iii)
3. (a) - (iii), (b) - (i), (c) -(iv), (d) - (ii)
4. (a) - (iii), (b) - (ii), (c) -(iv), (d) - (i)

Answer 1

Correct Answer - Option 3 : (a) - (iii), (b) - (i), (c) -(iv), (d) - (ii)

Concept:

• Plants have different types of roots.
• Some store food, some breathe some hang from the branches.
• Not all roots are underground.

Explanation:

Root type	Description
Carrot	In carrots, roots are modified for storing reserve food materials. These modified roots usually are swollen and assume different forms.
Stilt root	Stilt roots are adventitious aerial roots. They grow obliquely downward from the main stem's basal nodes and attach firmly to the soil.  they provide anchorage to plants and do not provide much support.
Pneumatophores	A specialised root that rises out of the water or mud upwards to enter the air. They gain oxygen for the root systems of trees living in swampy or tidal environments. Example: Mangrove
Prop roots	Banyan trees are characterized by aerial roots, that hang from the branches. These roots mature into thick, woody trunks, called prop roots. Prop roots can become indistinguishable from the primary trunk with age. They provide support to the main trunk to bear the load of the tree.

Thus, the correct match is (a) - (iii), (b) - (i), (c) -(iv), (d) - (ii)

List-I (Root type)	List-II (Function)
(a) Carrot	(iii) store food
(b) Stilt root	(i) anchorage
(c) Pneumatophores	(iv) respiration
(d) Prop roots	(ii) load-bearing
