Question
What is the right percentage of solar energy that is photosynthetically active radiation (PAR)?
- 100 percent
- 85 percent
- 20 percent
- 50 percent
Hint:
Only half of solar radiation forms PAR.
The correct answer is: 50 percent
- The spectral range of solar radiation that organisms utilize in the photosynthesis process is called as photosynthetically active radiation.
- The wavelength is between 400 to 700 nm in the light spectrum.
- The chlorophyll present in plants absorb this light and utilize it for photosynthesis.
- Around 50% of the solar radiation forms the photosynthetically active radiation.
