Understanding Avicennia and Pneumatophores
Avicennia, commonly known as mangrove plants, are well-adapted to salty, coastal environments. One of their distinctive features is the presence of pneumatophores.
What are Pneumatophores?
- Pneumatophores are specialized aerial roots that extend above the waterlogged soil.
- These structures are crucial for gas exchange, allowing the plant to absorb oxygen directly from the air.
Assertion: Avicennia has Pneumatophores
- This statement is true. Avicennia species possess pneumatophores which emerge from their root system.
- Their presence is a key adaptation for survival in anaerobic (low oxygen) soil conditions typical of mangrove ecosystems.
Reason: Pneumatophores help the plant to get oxygen for respiration
- This reason is also true. The primary function of pneumatophores is to facilitate oxygen uptake for respiration.
- In waterlogged environments, where soil oxygen levels are low, these structures ensure that the plant can still perform essential metabolic processes.
Correct Explanation of the Assertion
- The reason correctly explains the assertion, as the presence of pneumatophores directly aids in the respiratory needs of Avicennia.
- Therefore, both the assertion and reason are true, and the reason provides a correct explanation for why Avicennia has pneumatophores.
Conclusion
- The answer is option 'A' because both the assertion and reason are true, and the reason accurately explains the assertion regarding the function of pneumatophores in Avicennia species.
