what factors affect the rate of photosynthesis?
how does light intensity affect the rate of photosynthesis?
The photosynthesis inhibitors include triazines, phenylureas, uracils,benzothiadiazoles, nitriles, carbamate and dicarboxylic acid. Photosynthesis inhibitorsshut down the photosynthetic (food producing) process in susceptible plants by binding tospecific sites within the plant chloroplast. Inhibition of photosynthesis could result ina slow starvation of the plant; however, in many situations rapid death occurs perhapsfrom the production of secondary toxic substances.
how does temperature affect the rate of photosynthesis?
Green plants and other photosynthetic organisms trap light energy and synthesize carbohydrate molecules via metabolic processes collectively called photosynthesis.
How will herbicide affect a chloroplast's ability ..
Therefore in graph (c) the horizontal axis could be also labelled relative light intensity, a proportional linear relationship with the rate of photosynthesis.

Herbicide resistance, on the other hand, implies that a genetic change has caused a formerly susceptible population of a species to become resistant to an herbicide. Herbicide resistance arises from the process of adaptive evolution, whereby mutations change the physiology of plants in such a way that the herbicide is less effective. Under the continued selection pressure exerted by the herbicide(s), resistant plants with the new genotype are not controlled, and their offspring build up in the population (). Depending on the initial frequency and genetic basis of resistance, the regularity and rate of herbicide applications, and the reproductive system of the weed, it may take from a few to many generations for resistance to become apparent (; ).
