Explanation:

Plants have evolved to endure drought stress with morphological, physiological, and biochemical adaptations:

1.Drought resistance (DR) is a broader term applied to plant species with adaptive features which enables plants to escape, avoid and tolerate drought stress.
2.Drought escape (DE) is the ability of a plant species to complete its life cycle before the onset of drought.Thereby, plants do not experience drought stress, as they are able to modulate their vegetative and reproductive growth according to water availability. Eg rapid plant growth during wet season and little growth during the dry season.
3.Drought avoidance (DA) involves the ability of plants to maintain relatively higher tissue water content,despite the water scarcity in the soil (saving for a deficit day).
4.Drought tolerance (DT) involves the plant enduring low water content on its tissues through various adaptive traits.
