Question
Which of the following affect the rate of photosynthesis?A:Light intensity onlyB:Light intensity and amount of waterC:Temperature, amount of carbon dioxide and light intensityD:Amount of water and temperature
Solution
The rate of photosynthesis is affected by several factors. These include:
-
Light Intensity: The rate of photosynthesis increases with light intensity to a certain point, after which it plateaus because all the chlorophyll molecules are being used.
-
Amount of Water: Water is a raw material for photosynthesis. Without enough water, the plant may close its stomata (pores) to prevent water loss, slowing down photosynthesis.
-
Temperature: Photosynthesis is a series of chemical reactions, which generally occur faster at higher temperatures. However, if it gets too hot, the rate may slow down because the enzymes that facilitate photosynthesis denature (lose their shape and functionality).
-
Amount of Carbon Dioxide: Carbon dioxide is another raw material for photosynthesis. As with light intensity, increasing the amount of carbon dioxide increases the rate of photosynthesis up to a point.
So, the correct answer is C: Temperature, amount of carbon dioxide, and light intensity.
