1.	Photosynthetically active radiation (PAR) represents the following range of wavelengthA. 340-450 nmB. 400-700 nmC. 500-600nmD. 400-950 nm
Answer» Correct Answer - B Photosynthetically active region (PAR) of solar radiation is visible region. It consists of radiations having wavelength between 400 to 700 nm. Green plants use this wavelength in the process of manufacture of food, i.e., photosynthesis.
