Question

what is photosynthesis ?
​

Answer 1

• Photosynthesis is a process in which green plants and other living organisms make their own food by absorbing sunlight, water, carbon dioxide, oxygen, nutrients, and energy.
• Plants involve the green pigment called chlorophyll to generate oxygen.
• During this process light energy is converted into chemical energy.
• Equation for photosynthesis is: 6CO2+6H2O+(energy)➡️C6H12O6 +6O2 Carbon Dioxide+ water+ energy.

Answer 2

Photosynthesis is the mechanism used by plants and other organisms, having chloroplast in their cells to convert light energy into chemical energy for the metabolic activities of the plant.

Explanation:

Photosynthesis is the mechanism used by plants and other organisms, having chloroplast in their cells to convert light energy into chemical energy for the metabolic activities of the plant or organism such as algae.  

The Chlorophyll present in the chloroplast of the cells absorbs light energy essentially from sun and converts it to chemical energy.

The water taken by the roots from soil, carbon dioxide absorbed from the atmosphere in the presence of sunlight break down food molecules of carbohydrates, starch and sugars, releasing energy. As a result of which Oxygen is released into the atmosphere as a bi-product of this chemical reaction.

Photosynthesis helps in maintaining the atmospheric oxygen levels to sustain life on earth. The carbon dioxide present in the atmosphere is taken up by the plants and oxygen is released into the atmosphere.
