Final answer:
Photosynthetic rate is influenced by temperature and light. Temperature affects the activity of enzymes involved in photosynthesis, while light provides the energy needed for the process.
Step-by-step explanation:
Photosynthetic rate is influenced by temperature and light. Temperature affects the rate of photosynthesis as it influences the activity of enzymes involved in the process.
As temperature increases, the rate of photosynthesis generally increases until it reaches an optimal level, after which it declines. Light is necessary for photosynthesis to occur as it provides the energy needed for the process.
Different plants have different light requirements, and insufficient or excessive light can affect photosynthetic rate.
