Question

The optimum temperature for photosynthesis to occur is ___ to ___.

• A. $20°C$
• B. $25°C$

Answer 1

Photosynthesis:

1. The phenomenon by which green plants synthesize food is called photosynthesis.
2. Water and carbon dioxide are photosynthetic raw materials that form glucose and oxygen in presence of sunlight.
3. $6{\mathrm{CO}}_2(\mathrm{carbon}\mathrm{dioxide})+6{\mathrm{H}}_2\mathrm{O}\left(\mathrm{water}\right)\underset{}{\overset{\mathrm{Sunlight}}{\to }}{\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\left(\mathrm{glucose}\right)+6{\mathrm{O}}_2\left(\mathrm{oxygen}\right)$
4. Temperature regulates the enzymes involved in photosynthesis.
5. The optimum temperature of the photosynthetic enzymes ranges between $20°\mathrm{C}-25°\mathrm{C}$.
6. At very lower and very high temperatures the process of photosynthesis stops.

The optimum temperature for photosynthesis to occur is $\mathbf{20}\mathbf{°}\mathbf{C}$ to $\mathbf{25}\mathbf{°}\mathbf{C}$.
