How Light Intensity Affects The Rate Of Photosynthesis

WebNov 2, 2024 · More light causes more photosynthesis because plants need light to produce food. The more light they have, the more food they can make. According to the Emerson enhancement effect, the rate of photosynthesis increases when the chloroplast is exposed to a light wavelength of 680 nm and 700 nm. Webphotosynthesis is reduced and the light saturation point is decreased. (The light saturation point is the intensity at which additional increases in light do not increase photo - synthesis.) This means the value of supplemental lighting is marginalized at a low CO2 concentration.
