Root modification helps in the absorption of moisture from the atmosphere

Options

A. Pneumatophore
B. Velamen roots
C. Nodular root
D. Balancing root

Answer

**Step-by-Step Solution:**

1. **Understanding Root Modifications**: The question asks about root modifications that aid in the absorption of moisture from the atmosphere. Roots can adapt to various environments, leading to different modifications.

2. **Identifying Root Types**: We need to analyze different types of roots to find which one specifically helps in moisture absorption from the atmosphere.

3. **Examining Pneumatophores**: Pneumatophores are lateral roots that extend above the water surface in marshy areas. Their primary function is to facilitate gas exchange for submerged roots, not specifically for moisture absorption from the atmosphere.

4. **Examining Velamen Roots**: Velamen roots are characterized by a thick corky epidermis and are aerial roots. Their structure allows them to absorb moisture from the environment, making them suitable for this question.

5. **Examining Nodular Roots**: Nodular roots are found in leguminous plants and are primarily involved in nitrogen fixation, not moisture absorption.

6. **Examining Balancing Roots**: Balancing roots are found in aquatic plants and provide support, but they do not play a role in moisture absorption from the atmosphere.

7. **Conclusion**: Among the options discussed, the velamen roots are the correct answer as they specifically help in the absorption of moisture from the atmosphere.

**Final Answer**: Velamen roots help in the absorption of moisture from the atmosphere.
