Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas as raw materials. Chlorophyll is a substance in all green plants, especially in the leaves.

Answer 2

◉ Definition:-

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

⇝ The process of photosynthesis is commonly written as:

• 6CO2 + 6H2O → C6H12O6 + 6O2.

This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products. The sugar is used by the organism, and the oxygen is released as a by-product.

➽ Steps:-

It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast:

1. absorption of light,
2. electron transport leading to the reduction of NADP+ to NADPH,
3. generation of ATP,
4. convers
