What is the percentage of photosynthetically active radiation (PAR) in the incident solar radiation ?
आगमनित सौर विकिरण में प्रकाश-संश्लेषण सक्रिय विकिरण का प्रतिशत कितना होता है?
Detailed Solution & Logic
50%
Explanation / व्याख्या
Photosynthetically Active Radiation (PAR) is the portion of sunlight that plants can use for photosynthesis. It includes light in the wavelength range of 400–700 nanometers (nm).
प्रकाश-संश्लेषण सक्रिय विकिरण (PAR) सूर्य के प्रकाश का वह भाग है जिसका उपयोग पौधे प्रकाश-संश्लेषण (Photosynthesis) के लिए करते हैं। इसका तरंगदैर्ध्य (Wavelength) 400–700 नैनोमीटर (nm) के बीच होता है।
According to standard ecology and biology concepts, about 50% of the incident solar radiation is photosynthetically active radiation (PAR).
पारिस्थितिकी एवं जीवविज्ञान के अनुसार, आगमनित सौर विकिरण का लगभग 50% भाग प्रकाश-संश्लेषण सक्रिय विकिरण (PAR) होता है।
Extra Facts / अतिरिक्त तथ्य
Green plants capture only a small fraction of the available PAR for photosynthesis.
हरे पौधे उपलब्ध PAR का केवल एक छोटा भाग ही प्रकाश-संश्लेषण के लिए उपयोग कर पाते हैं।
The process of photosynthesis can be represented by:
$6CO_2 + 6H_2O \rightarrow C_6H_{12}O_6 + 6O_2$
During photosynthesis, plants convert solar energy into chemical energy stored in glucose.
प्रकाश-संश्लेषण के दौरान पौधे सौर ऊर्जा को ग्लूकोज़ में संचित रासायनिक ऊर्जा में परिवर्तित करते हैं।
Among visible colors, red and blue light are most effective for photosynthesis.
दृश्य प्रकाश में लाल और नीला प्रकाश प्रकाश-संश्लेषण के लिए सबसे अधिक प्रभावी होते हैं।
Only about 2–10% of PAR is actually captured by plants and used in photosynthesis.
उपलब्ध PAR का केवल 2–10% भाग ही वास्तव में पौधों द्वारा ग्रहण कर प्रकाश-संश्लेषण में उपयोग किया जाता है।
