(A) From the region of elongation, some of the epidermal cells form root hairs.
(B) Pneumatophores are seen in Rhizophora.
(C) Adventitious roots are seen in the Banyan tree.
(D) Maize and sugarcane have prop roots.

• A. (A) and (D)
• B. (A), (C) and (D)
• C. (C) and (D)
• D. (B) and (C)

Answer 1

The correct option is D (B) and (C)

Adventitious roots do not arise from the radical of the seed. Instead, they can originate from the plumule parts such as stem, branches, leaves. Hence, they are termed as adventitious roots. Prop roots are the modified roots that give mechanical support to the aerial branches. The lateral branches grow vertically downward into the soil and act as pillars. For example, banyan tree. Pneumatophores are specialized aerial roots that enable plants to breathe air in habitats that have waterlogged soil. The roots may grow down from the stem or up from typical roots. For example, mangrove family of plants (Rhizophoraceae).

Thus, the correct answer is option D.
