Question

Quizplus · Accepted Answer

The wilting point is the point at which a plant cannot extract enough water from the soil to sustain its normal bodily functions (such as maintaining turgor pressure in its cells). It occurs when the soil is so dry that it becomes difficult for the plant to obtain water even if it extends its root system as far as it can. Therefore, a plant that is unable to extract needed water from soil has reached its wilting point.
