Limiting factors
Karten in diesem Stapel (10)
- 1What is a limiting factor?A single factor that when in short supply can limit the rate of a process (e.g. photosynthesis)
- 2Name three limiting factors of photosynthesis.1) Light intensity
2) Carbon dioxide concentration
3) Temperature - 3Why does the rate of photosynthesis speed up when light intesity increases?Because light is necessary for a plant to photosynthesise and more of it will make the plant photosynthesise quicker.
- 4What would a graph to show the rate of photosynthesis against light intensity look like?
- 5What happens to the rate of photosynthesis and enzymes if it gets too cold?The rate of photosynthesis decreases and enzymes have little energy.
- 6What happens to the plant if the temperature gets too hot?Plants cannot photosynthesise if it is too hot, the enzymes denature and the stomata close to prevent water loss.
- 7What would a graph showing rate of photosynthesis against temperature look like?
- 8What happens to the rate of photosynthesis as carbon dioxide concentration increases?As carbon dioxide concentration increases, the rate of photosynthesis increases because carbon dioxide is necessary for the process.
- 9What would a graph showing carbon dioxide concentration against rate of photosynthesis look like?
- 10If the light intensity and carbon dioxide are at a constant, what must be the limiting factor and why?Temperature must be the limiting factor because when the other variables are constant, increasing the variables does not increase the rate of photosynthesis
