Percentage of Photosynthetically Active Radiation (PAR) in Incident Solar Radiation
PAR refers to the portion of solar radiation that plants can use for photosynthesis. It is typically measured in the wavelength range of 400 to 700 nanometers. The percentage of PAR in the incident solar radiation varies depending on different factors.
Explanation:
- Option a) 100%: This is not the correct answer because not all solar radiation received by plants is in the form of PAR. The total solar radiation includes ultraviolet and infrared radiation, which are not utilized by plants for photosynthesis.
- Option b) 50%: This is the correct answer. On average, about half of the incident solar radiation is in the form of PAR. This means that 50% of the sunlight that reaches plants is suitable for photosynthesis.
- Option c) 1-5%: This range is too low for the percentage of PAR in incident solar radiation. Plants require a higher percentage of PAR to carry out efficient photosynthesis.
- Option d) 2-10%: While this range is closer to the correct answer, it still overestimates the percentage of PAR in incident solar radiation. The actual percentage is around 50%.
In conclusion, the percentage of PAR in incident solar radiation is approximately 50%, making option b the correct choice. This highlights the importance of PAR for plant growth and productivity.
