Why is plant growth slow in cold regions?
Answer and explanation
Correct answer: Low temperature limits photosynthesis and growth
At low temperatures, plant processes such as photosynthesis and enzyme activity slow down. Cold regions also often have a short growing season, giving plants less time to grow. Option B is incorrect because low temperature generally reduces, rather than increases, root activity and water absorption. Exam tip: lower temperature can reduce both the rate and duration of plant growth.
