(d) Available during day: __
(a) Chlorophyll: A green colour pigment present in the leaves. It helps leaves to capture the energy of the sunlight.
(b) Water, minerals: These are the raw materials which are essential to carry out the process of photosynthesis. They are obtained from the soil.
(c) Carbon dioxide: The raw material which is available in the air for photosynthesis. Carbon dioxide from the air is taken in through the tiny pores present on the surface of the leaves. These tiny pores are called stomata.
(d) Sunlight: The process of photosynthesis takes place only in the presence of sunlight. The chlorophyll helps leaves to capture the energy of the sunlight.
The equation showing the process of photosynthesis is as follows:
Carbon dioxide + Water Sunlight,Chlorophyll−−−−−−−−−−−−−→ Carbohydrate + Oxygen
