Photosynthesis is the process that produces organic matter from simple inorganic molecules from the sun’s energy. The rate of photosynthesis can be affected by a number of variables including: the intensity of light the amount of water the carbon dioxide concentration temperature and the presence of any limiting factors.
The intensity of light is one of the most important factors affecting the rate of photosynthesis. The reason for this is that photosynthesis is a light-dependent process meaning that it requires light in order to occur. The amount of light that a plant receives will determine how much energy is available for photosynthesis to take place. If a plant is receiving a low intensity of light then the rate of photosynthesis will be lower because there is less energy available.
The amount of water also affects the rate of photosynthesis. Plants need water in order to photosynthesize and if they do not have enough water the rate of photosynthesis will be lower. The amount of water that a plant needs will depend on the plant species and the environmental conditions.
The carbon dioxide concentration also affects the rate of photosynthesis. Carbon dioxide is used by plants during photosynthesis and if there is not enough carbon dioxide present the rate of photosynthesis will be lower. The carbon dioxide concentration can be affected by things like the level of atmospheric pollution.
Temperature also affects the rate of photosynthesis. In general photosynthesis occurs more quickly at higher temperatures. However if the temperature gets too high photosynthesis can actually stop altogether.
There are also a number of other factors that can affect the rate of photosynthesis. These include the presence of any limiting factors such as certain herbicides that can inhibit photosynthesis.
