Question

Which wavelengths of light are more useful for photosynthetic plants?

Answer 1

Photosynthesis:

1. The phenomenon by which green plants synthesize food in the presence of sunlight by utilizing carbon dioxide and water.
2. Photosynthesis involves green pigments called chlorophyll located in chloroplasts of plant cells.
3. Chlorophyll molecules receive solar energy and get excited to release electrons utilized in photosynthesis.
4. $6{\mathrm{CO}}_2(\mathrm{carbon}\mathrm{dioxide})+6{\mathrm{H}}_2\mathrm{O}\left(\mathrm{water}\right)\underset{\mathrm{Sunlight}}{\overset{\mathrm{Chlorophyll}}{\to }}{\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\left(\mathrm{glucose}\right)+6{\mathrm{O}}_2\left(\mathrm{oxygen}\right)$
5. The important wavelengths to excite the chlorophyll molecules in plants are red (600-700 nm) and blue (400-500 nm).
