Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A stress response where plants may experience severe stress that could lead to death.
A
susceptible
B
tolerant
C
resistant
D
avoidance
Explanation: 

Detailed explanation-1: -Stomatal response, ROS scavenging, metabolic changes, and photosynthesis are all affected when plants are subjected to water stress. These collective responses lead to an adjustment in the growth rate of plants as an adaptive response for survival.

Detailed explanation-2: -Plant stress can be divided into two primary categories namely abiotic stress and biotic stress. Abiotic stress imposed on plants by environment may be either physical or chemical, while as biotic stress exposed to the crop plants is a biological unit like diseases, insects, etc.

Detailed explanation-3: -In response to salt stress, plant cells accumulate compatible solutes and redistribute ions, which enables them to acclimate to a low soil water potential. Additionally, the endogenous abscisic acid (ABA) content increases, followed by changes in principle genetic expression in salt stress conditions.

Detailed explanation-4: -Abiotic stress includes temperature, ultraviolet radiation, salinity, floods, drought, heavy metals, etc., which results in the loss of important crop plants globally, while biotic stress refers to damage caused by insects, herbivores, nematodes, fungi, bacteria, or weeds.
