Cellular aspects involved:
editWhen a plant does not have access to water, it undergoes stress. This stress is referred to as a water deficit. [1] Plants have undergone many adaptations to better tolerate water loss and water deficits. Three cellular mechanisms utilized by a plant to combat water deficits are osmotic adjustment, whole-plant signaling, and whole-plant control of shoot and root systems. [1]
Osmotic adjustment
editOsmotic adjustment is a cellular mechanism that helps plants acclimate to drier climates. (citation) This mechanism helps plants adapt to droughts by alter it's metabolism in order to maintain water content. (Citation)
