Detailed Solution

Definition:
Photosynthesis is the process by which green plants, algae, and some bacteria use sunlight to make food. In this process, plants take in carbon dioxide from the air and water from the soil, and in the presence of sunlight and chlorophyll, they produce glucose (a type of sugar) and release oxygen.

Explanation:
This process is important because it provides food and oxygen for all living organisms. It is the primary source of energy for all ecosystems.

Chemical Equation:

6CO_{2} + 6H_{2}O \xrightarrow[\text{Chlorophyll}]{\text{Sunlight}} C_{6}H_{12}O_{6} + 6O_{2}

$6$ $CO$ $2$ $$ $+$ $6$ $H$ $2$ $$ $O$ $Sunlight$ $Chlorophyll$ $$ $C$ $6$ $$ $H$ $12$ $$ $O$ $6$ $$ $+$ $6$ $O$ $2$ $$

This means 6 molecules of carbon dioxide and 6 molecules of water, in the presence of sunlight and chlorophyll, produce one molecule of glucose and 6 molecules of oxygen.
