How to get a girlfriend and how to able to talk to other kids without being shy
The correct answer is A - chlorophyll.
It is a green pigment found in the chloroplasts of green plants. Chloroplasts are mostly found in the leaves of green plants and also in some algae.
Plants use chlorophyll to trap light energy from the sun. Without the light energy, plants cannot be able to carry out the process of photosynthesis, which converts water and carbon dioxide into starch that plants use for food.
Photosynthesis also releases oxygen which is vital for animal life.
