Q. What is chlorophyll ?
Q. Name the various factor which affect the rate of photosynthesis.
Q. Define photolysis.​

Answer 1

➥ Even, when an organism is asleep, various biological processes keep on occurring in its body which requires energy.

➥ During photosynthesis‚ “Solar energy is converted into chemical energy”.

➥ “Chlorophyll” is a green coloured pigment found in plants that helps in absorbing sunlight used in photosynthesis.

➥ Several factors which affect the rate of photosynthesis:

• Light.
• Temperature.
• Water.
• CO2.

➥ “Photolysis” is the process by which water is split into oxygen, which is released into the atmosphere, and hydrogen.
