Question

These are the roots in a sequence to absorb moisture, support, water minerals from other plants.

• A. Nodular roots, Haustorial roots, Stilt roots
• B. Velamen roots, Stilt roots, Haustorial roots
• C. Stilt roots, Prop roots, Haustorial roots
• D. Pneumatophores, Prop roots, Stilt roots

Hint:

When dealing with root types, remember the functions they serve. This helps in understanding their sequence of occurrence.

Answer 1

The Correct Option is B

To solve the problem, we need to identify the correct type of roots that absorb moisture, provide support, and take up water minerals from other plants.

1. Understanding the Function of Roots:
Roots have various adaptations for specific functions. Some roots are specialized to absorb moisture, others to provide support or take in water from neighboring plants.

2. Types of Roots in Context:
The root types mentioned in the options are:

• Nodular roots: Found in plants like legumes, these roots form nitrogen-fixing nodules.
• Haustorial roots: These roots are parasitic and absorb nutrients and water from other plants.
• Stilt roots: These roots are seen in some plants like mangroves and help in providing support.
• Velamen roots: These are specialized roots in epiphytes, helping in moisture absorption.
• Pneumatophores: These roots help with breathing and are found in plants in swampy areas.
• Prop roots: These roots support the plant and are seen in some trees like banyan trees.

3. Analyzing the Correct Combination:
The question asks for roots that absorb moisture, support, and take water minerals from other plants. The best combination of roots in the options provided that fits these criteria is:
Velamen roots, Stilt roots, Haustorial roots

Final Answer:
The correct option is (B) Velamen roots, Stilt roots, Haustorial roots.

Answer 2

The correct sequence of roots is: Velamen roots, which absorb moisture, Stilt roots, which provide support, and Haustorial roots, which help absorb minerals from other plants.
The sequence follows the order of their function, from moisture absorption to support and then mineral absorption.
