Which of the followings describes a plant response to heat stress?
Correct answer: A. Production of heat shock proteins
- A. Production of heat shock proteins
- B. Closing of stomata
- C. Production of abscisic acid
- D. Production of fructans
Explanation
When plants are exposed to stress, the synthesis of normal proteins is decreased while the expression of special genes are up-regulated and, as a result, the synthesis of HSPs is triggered.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
