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
