Question

Define the following : Photosynthesis.

Answer 1

Photosynthesis: The process in which green plants utilize carbon dioxide and water in the presence of sunlight and chlorophyll to produce food and oxygen gas, is called photosynthesis. In this process, food is obtained in the form of glucose which is stored by plants as starch.

$$\begin{gathered} \mathrm{Carbon}+\mathrm{Water}\stackrel{\mathrm{Sunlight},\mathrm{Chlorophyll}}{\to }\mathrm{Food}+\mathrm{Oxygen} \\ \mathrm{dioxide}\left(\mathrm{glucose}\right) \end{gathered}$$

$6{\mathrm{CO}}_2+6{\mathrm{H}}_2\mathrm{O}\stackrel{\mathrm{Sunlight},\mathrm{Chlorophyll}}{\to }{\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6+6{\mathrm{O}}_2$
