photosynthesis occour more in________ and_________ light rays and less are not at all in_____ light rays.​

Answer 1

Answer:

Light is an essential factor for photosynthesis. There is a linear relationship between incident light and CO

fixation at low light intensities. At higher light intensities, gradually the rate does not show further increase as other factors become limiting. Light between 400-700 nm wavelength constitute the photosynthetically active radiation (PAR). Maximum absorption of light by chlorophyll a occurs in red and blue regions of the absorption spectrum. So that, the rate of photosynthesis is maximum in red and blue light of the visible spectrum. Minimum photosynthesis takes place in the green light. Minimum absorption of chlorophyll a occurs in the green region because plants themselves are green due to the pigment Chlorophyll.
