(a) Photosynthesis converts energy X into energy Y. What are X and Y? (b) State the various steps involved in the process of photosynthesis.

• Photosynthesis is a process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide The chlorophyll present in leaves absorb light energy from the sun and convert into chemical energy.

So here X is light energy and Y is chemical energy.

• The various steps involved in the process of photosynthesis are:
  • Absorption of light energy through the sun by chlorophyll present in
  • Conversion of light energy chemical In this process, the water molecule splits into its respective components hydrogen and oxygen.

• Carbon dioxide is reduced into carbohydrates like glucose by light energy utilizing the hydrogen and oxygen produced in the above step.
