What is Photosynthesis? - QS Study
QS Study

Photosynthesis is a biochemical process. In this process green parts (specially leaves) of plants manufacture carbohydrate food by CO2 and water with the help of energy obtained from sunlight. Here light energy is converted to chemical energy. Plants absorb CO2 and release O2 as bi-product in the process of photosynthesis. The components required for this process are: –

(i) Light,

(ii) Chlorophyll,

(iii) Water and,

(iv) Carbon dioxide (CO2).

Chlorophyll pigments are present in the chloroplasts of plant cells. Water absorbed by roots reaches to the mesophyll cells in the leaves. The process of photosynthesis is shown by the following reaction:

“Photosynthesis is such a biochemical reaction by which chloroplast, in the plant cell, uses the energy, received from the photon of sunlight, manufactures carbohydrate food by CO2 of the atmosphere and water and other organic substances in the CO2 cell.
