Most scientists agree that global warming is underway; thus it is important to know how plants respond to heat stress. Which of the following is an immediate short-term response of plants to heat stress?
A)the production of heat-shock carbohydrates unique to each plant
B)the production of heat-shock proteins like those of other organisms
C)the opening of stomata to increase evaporational heat loss
D)their evolution into more xerophytic plants
E)all of the above

Question

Quizplus · Accepted Answer

The immediate short-term response of plants to heat stress is the production of heat-shock proteins like those of other organisms. These proteins help in stabilizing the protein structures against heat denaturation. The production of heat-shock carbohydrates is a long-term response, and the opening of stomata and evolution into more xerophytic plants are not immediate responses to heat stress.
