Answer 2

Answer:

Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive. Carbon dioxide, water and light are all needed for photosynthesis to take place. Chlorophyll is a green photosynthetic pigment found in plants, algae, and cyanobacteria. Chlorophyll is vital for photosynthesis, it allows plants to absorb energy from light.

Iodine solution is not required for photosynthesis.

Also green plants, due to the presence of chlorophyll in their leaves, can perform photosynthesis in the presence of light by using carbon dioxide as a raw material. Nitrogen is not needed for it .
