Read each question carefully and provide concise answers based on your understanding of photosynthesis and its influencing factors.
1. Which of the following is NOT a primary factor affecting the rate of photosynthesis?
Light intensity
Carbon dioxide concentration
Oxygen concentration
Temperature
2. At very high light intensities, the rate of photosynthesis may decrease due to:
Photoinhibition
Increased water uptake
Stomatal closure
Higher CO2 absorption
1. The process by which plants convert light energy into chemical energy is called .
2. Increasing the concentration of generally increases the rate of photosynthesis up to a certain point.
3. Photosynthesis enzymes function optimally within a specific range.
1. Explain the concept of a limiting factor in relation to photosynthesis.
2. Describe how extreme temperatures can negatively impact the rate of photosynthesis.
1. The rate of photosynthesis continuously increases with increasing light intensity, without limit.
True
False
2. Water availability is a crucial factor for photosynthesis because it is a reactant in the light-dependent reactions.
True
False
Match each factor with its effect on photosynthesis.
1. Low CO2 concentration
a. Reduces enzyme activity
2. High light intensity (beyond optimum)
b. Limits carbon fixation in Calvin cycle
3. Suboptimal temperature
c. Can cause photoinhibition
