• D. Adventitious roots are present in Banyan tree

Answer 1

Answer:

C. Most of the monocotyledons adopt tap root system

• a) Radicle grows to form a primary root inside the soil: Correct—the radicle is the embryonic root that gives rise to the primary root.

• b) From the primary roots grows the secondary roots from lateral surfaces: Correct—secondary (lateral) roots grow out from the primary root.

• c) Most of the monocotyledons adopt tap root system: Incorrect—monocotyledons have a fibrous root system, not a tap root system. The primary root is short-lived, and a network of thin roots develops from the stem base.

• d) Adventitious roots are present in Banyan tree: Correct—banyan trees develop extensive adventitious roots from their branches.
