Question

Which light range is most effective in photosynthesis?

Answer 1

Photosynthesis:

1. Photosynthesis is the process by which phototrophs or plants which require light for the preparation of food convert light energy into chemical energy, which is then used for cellular power.
2. Sugars are used as a means of storing chemical energy. Water and carbon dioxide are used to make them.
3. Photosynthesis takes place in chloroplasts, which are cellular organelles. Chlorophyll, a green pigment found in such organelles, is responsible for the leaves' distinctive green color.

In the blue and red light spectrums, photosynthesis is most efficient:

1. The blue and red light spectrum is most efficient in photosynthesis because both photosystems (PS I and PS II) absorb light with wavelengths in the red range (680 and 700 nm, respectively).
2. Carotenoids absorb blue light as well, passing the energy on to chlorophyll.
3. Chlorophyll absorbs light in the red region.
4. Because red light has the highest absorption by chlorophyll, it is the most effective wavelength for photosynthesis.
5. In photosynthesis, green light is the least effective.
