Question

Define Photosynthesis.

Answer 1

Photosynthesis:

• The process by which plants prepare their own food in the presence of sunlight, carbon dioxide present in the air, water, minerals, and chlorophyll present in leaves is known as photosynthesis.

$$\begin{gathered} 6{\mathrm{CO}}_2\left(\mathrm{g}\right)+12{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\underset{\mathrm{chlorophyll}}{\overset{\mathrm{sunlight}}{\to }}{\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\left(\mathrm{s}\right)+6{\mathrm{O}}_2\left(\mathrm{g}\right)+6{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right) \\ \mathrm{Carbon}\mathrm{dioxide}\mathrm{Water}\mathrm{Glucose}\mathrm{Carbon}\mathrm{dioxide}\mathrm{Water} \end{gathered}$$

• Photosynthesis is not limited to green plants, it is also a process that occurs in certain algae, specifically blue-green algae, and bacteria.
