Question

Given below is a diagrammatic representation of cross-section of a leaf:

1. Identify ‘P’ in the given diagram and write down its role in plants.
2. Write down a balanced equation of process of photo-synthesis.

Answer 1

i. P: Palisade mesophyll

Role: Palisade mesophyll cells contain a large number of chloroplasts. They are the main site of photosynthesis. These cells absorb maximum sunlight for food production.

ii. \[\ce{6CO2 + 12H2O ->[Ch;orophyll][Sunlight] \underset{[Glucose]}{C6H12O6} + 6O2 + 6H2O}\]
