The factors that affect the rate at which photosynthesis occurs are;

  • The intensity of light
  • Oxygen concentration
  • Temperature

Definition:

Photosynthesis put simply refers to a process by which plants manufacture their food in the presence of water, chlorophyll, sunlight, and CO2.

The photosynthesis process occurs mainly in the leaves of the plants.

Factors affecting rate at which photosynthesis are:

  • Temperature: Photosynthesis just like other biochemical reactions occurs best within a specific range of temperatures.

  • Light intensity: The amount of light required varies for different plants. Photosynthesis utilises up to 1.5 % of light at most in the process and so light is generally not a limiting factor at high intensity.

  • Oxygen: Optimum levels of oxygen are favourable for photosynthesis. Oxygen is needed for photorespiration in some plants and the major by-product of photorespiration is CO2 which is important for photosynthesis.
