NEETBotanyPlant - Growth and Development
What role does oxygen play in plant growth?
Options
- AIt helps in photosynthesis
- BIt provides structural support
- CIt releases metabolic energy essential for growth activities
- DIt acts as a nutrient
Correct answer
C. It releases metabolic energy essential for growth activities
Step-by-step solution
The plant cells grow in size by cell enlargement which in turn requires water. Turgidity of cells helps in extension growth. Thus, plant growth and further development is intimately linked to the water status of the plant. Water also provides the medium for enzymatic activities needed for growth. Oxygen helps in releasing metabolic energy essential for growth activities.
