¶¶¶Photosynthesis is a biological process used by all green plants to prepare food with the help of sunlight water and carbon dioxide. The word photosynthesis is derived from the Greek word “Photo” meaning light and “Synthesis” meaning connecting together. This means combining together with the help of light energy.

This biological process is also used by algae and several bacteria to convert solar energy into chemical energy. Oxygen is liberated as a by-product, and light is considered as the major factor to complete the process of photosynthesis. This process occurs usually when plants use light energy to convert carbon dioxide and water into glucose and oxygen gas. Leaves are made up of small cells which have a tiny structure known as chloroplasts. Each chloroplast contains a green coloured pigment called chlorophyll. Light energy is absorbed by chlorophyll molecules whereas carbon dioxide (CO2) and oxygen (O2) enter through the tiny pores of stomata located in the epidermis of leaves.

Oxygen is considered one of the most important by-products of this process on which most of the living organism depend upon. Glucose/Sugar is a form of carbohydrates that are processed during the process of photosynthesis. It is commonly used by green plants in the form of an energy source to produce leaves, fruits, flowers, and seeds. The glucose molecules then combine with each other to develop more complex carbohydrates like cellulose and starch. The cellulose is considered as the structural material that is used in plant cell walls. The overall reaction of photosynthesis process is:

6CO2 + 6H2O —> C6H12O6 + 6O2...
