What is Limiting Factors of Photosynthesis?
Within Biology, which covers cells, the human body, genetics, evolution, plants and ecosystems: the science of living things, this topic explains Limiting Factors of Photosynthesis. Biology topics show how living things work, from the cell up to whole ecosystems, with models you can explore step by step.
Check that you can explain Limiting Factors of Photosynthesis in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Limiting Factors of Photosynthesis helps you explain how living things stay alive and respond to their surroundings, which is central to biology exams.
Limiting Factors of Photosynthesis in detail
The rate of photosynthesis can be limited by light intensity, carbon dioxide concentration or temperature. A limiting factor is the one in shortest supply, which stops the rate from rising even if the other factors are increased.
As light intensity increases, the rate rises until another factor becomes limiting, and the graph levels off. Temperature affects enzymes, so very high temperatures denature them. Chlorophyll amount is another factor. Greenhouse growers control these factors with lighting, heating and carbon dioxide enrichment, balancing cost against improved yield.
