Effect is of extreme cold and hot in plant
Answers
Answer:
Explanation:
Generally, plants grow faster with increasing
air temperatures up to a point. Extreme
heat will slow growth and also increase
moisture loss. The temperatures for optimal
growth vary with the type of plant. Some
annual flowers and vegetables are extremely sensitive to cold, and transplants should
not be planted until temperatures are consistently warm.
Extremely hot or cold soil temperatures can
also hamper plant growth, as well as affect
seed germination.
Cool temperatures in fall trigger the plant to
reduce growth and store energy. As temperatures approach freezing, growth stops
and the plant (if perennial) becomes
dormant. Plants are better able to withstand
cold temperatures when dormant. A sudden
cold snap in late fall before the plant has
had a chance to harden off can do more
harm than sustained cold temperatures in
mid-winter
