- Engelmann
- Emerson
- Lavosier
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Engelmann studied the effect of different region of the visible spectrum on the rate of photosynthesis of different algae. .The amount of oxygen $ (C_{2}) $ released was found to be maximum in blue and red absorption bands of chlorophyll.

Processes Of Photosynthesis in Higher Plants:
Photosynthesis in higher plants involves the following processes:
- Light Reaction
- Dark Reaction
Light Reaction:
- This phenomenon occurs in the presence of light.
- The pigment absorbs light and produces energy in the form of ATP.
- The process involves- absorption of light, water splitting, the release of oxygen, and formation of ATP and NADPH.
Dark Reaction:
This process occurs in the absence of light in the stroma of the chloroplasts. The following cycles are involved in the process:
- Calvin Cycle (C3 Cycle)
- C4 Cycle (Hatch and Slack Pathway)
