Most scientists agree that global warming is under way;thus,it is important to know how plants respond to heat stress.Which of the following would be a useful line of inquiry to try to improve plant response to and survival of heat stress?
A)the production of heat-stable carbohydrates
B)increased production of heat-shock proteins
C)the opening of stomata to increase evaporational heat loss
D)protoplast fusion experiments with xerophytic plants

Question

Quizplus · Accepted Answer

Increased production of heat-shock proteins has been shown to help plants cope with heat stress by protecting cellular components from damage. This would be a useful line of inquiry to improve plant response to and survival of heat stress. The production of heat-stable carbohydrates may be helpful as well, but it is less well understood and may not have as direct of an impact on survival under heat stress. The opening of stomata to increase evaporational heat loss may be useful in some species but could also lead to excessive water loss if the available water supply is limited. Protoplast fusion experiments with xerophytic plants may not be directly related to heat stress and may not provide useful information for improving plant survival in a warmer climate.
