Nodulose Roots – Structure and Function

To solve this question, let’s first understand the structure and function of nodulose roots.

• Apart from absorbing water and minerals, roots may undergo modifications for other functions such as food storage, mineral fixation, or symbiotic association.
• Examples include tuberous roots (as in potato) and root nodules (as in leguminous plants).

Nodulose Roots

• Nodulose roots are a type of adventitious root modification.
• They swell at the apex due to the accumulation of food reserves.
• Example:Curcuma amada (mango ginger).

Mango ginger is closely related to common ginger but has a raw mango-like flavor. It is widely used as a spice, vegetable, and especially in pickles.

• Mirabilis: A perennial herb with tuberous roots, used in Ayurvedic medicine.
• Vanda: An orchid (epiphyte) with large aerial roots, not nodulose.
• Momordica: Has moniliform or beaded roots (adventitious roots modified for storage).

Correct Answer

Nodulose roots are found in Mango Ginger (Curcuma amada). Hence, the correct option is (D).
