Life processes
Why is energy required by an organism even during sleep? This is because even when an organism is asleep, various biological processes keep on occurring in its body which requires energy. Give the energy transformation that takes place in the process of photosynthesis. Solar energy is converted into chemical energy during photosynthesis. What is chlorophyll? Chlorophyll is a green coloured pigment found in the green leaves or green parts of the plant which traps solar energy for photosynthesis. Chlorophyll is present in cell organelles called chloroplasts. Name the various factors which affect the rate of photosynthesis. The factors which affect the rate of photosynthesis are light, water, temperature and carbon dioxide. Define photolysis. The phenomenon of breaking down of water molecule using solar energy absorbed by chlorophyll molecules is known as photolysis. Define light reaction. A chemical reaction, which take place only in the presence of light, is called light reac...
