Question
Explain the mechanism of photosynthesis.
Solution
Photosynthesis is a process by which plants produce their own food by utilizing sunlight, CO2 and water. CO2 and water are converted to carbohydrates with the evolution of oxygen. Photosynthesis reaction can be given by the following reaction -
\[\ce{6CO2 + 6H2O \overset{Sunlight}{->}C6H12O6 + 6O2}\]
Process of Photosynthesis is divided into 4 processes -
- Absorption of light energy by chlorophyll
- Conversion of light energy into chemical energy
- Splitting of water molecules into Hydrogen and Oxygen
- Reduction of CO2 to produce carbohydrates

The transport system in plants consists of two kinds of tissues X and Y. The tissue X is made up of living cells and consists of two components A and B. The component A has tiny pores in its end walls and contains only cytoplasm but no nucleus. On the other hand, component B has cytoplasm as well as nucleus. The tissue Y is made up of dead cells and consists of two components C and D. The component C has open ends whereas component D does not have open ends. In flowering plants, either only C or both C and D transport water but D is the only water conducting tissue in non-flowering plants.
