Question

 List the three events that occur during the process of photosynthesis. Explain the role of stomata in this process.

Answer 1

The events that occur in plants during photosynthesis are—

• Absorption of sunlight by the green pigment chlorophyll

• Conversion of light energy into chemical energy and the splitting of water molecule into oxygen and hydrogen

• Reduction of carbon dioxide into glucose

Role of stomata

Stomata are tiny pores present mainly on the surfaces of leaves. They are also present on the surface of young stems and roots. Stomata are mainly engaged in the exchange of gases (entry of CO₂ and release of O₂) associated with photosynthesis.
