Answer 1

Answer: (A), (B), (C)

Both prop and stilt roots are meant for mechnical support.

• Roots and stems of some plants are modified to perform additional functions like storage, support and respiration.
• Stems of maize and sugarcane have supporting roots that arise from the lower nodes of the stem. These are called stilt roots.
• Banyan trees have roots that grow vertically downwards from their aerial branches. They provide extra support to these trees and are called prop roots.
