Photosynthesis- Limiting Factors in Photosynthesis Flashcards
What is a limiting factor?
A limiting factor is a variable that causes a noticeable change in a system’s output. In the case of photosynthesis, a limiting factor is anything that prevents photosynthesis from occurring at its maximum rate.
How can light intensity act as a limiting factor of photosynthesis?
Light intensity
If the light is too low, the rate of photosynthesis will decrease.
How can the number of chloroplasts act as a limiting factor of photosynthesis?
The number of chloroplasts in a plant also affects the rate of photosynthesis. Plants with more chloroplasts photosynthesize faster.
How can water supply act as a limiting factor of photosynthesis?
While water isn’t usually a limiting factor because plants only need a small amount, a lack of water can cause the plant’s stomata to close, which limits its carbon dioxide intake.
How can carbon dioxide concentration act as a limiting factor of photosynthesis?
If the carbon dioxide level is too low, the rate of photosynthesis will decrease. However, high levels of carbon dioxide won’t harm the process, the plant will just reach a maximum rate.
How can temperature act as a limiting factor of photosynthesis?
If the temperature is too low or too high, the rate of photosynthesis will decrease. At very high temperatures, the enzymes needed for photosynthesis can denature, which can stop the process.
