Answer
[ALL of these] are factors that can limit the rate of photosynthesis.
Explanation
Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. Photosynthesis in green plants harness sunlight to synthesize foods with the help of carbon dioxide and water. There are certain key factors that can affect or limit the rate of photosynthesis. Let's break down each option:1. 'Carbon Dioxide Concentration' - Carbon Dioxide (CO2) is one of the main components utilized by plants during photosynthesis. A higher concentration can increase the rate of photosynthesis up to a certain point. 2. 'Temperature' - Like all enzymatic reactions, the rate of photosynthesis increases as the temperature increases, up to a certain point, at which either the enzyme catalyzing the reaction or the plant cell itself gets damaged. 3. 'Light intensity' - Initially, as the intensity of light increases, so does the rate of photosynthesis. But slowly it plateaus off when other factors become limiting, i.e., limiting the rate of photosynthesis.Hence all options provided the direct role into enhancing photosynthesis efficiency and can limit the reaction if found inadequate.
