GENERAL KNOWLEDGE

Detailed explanation-1: -Vegetable plants transpire water from their leaves, creating suction on the water at the root surface that draws the nutritious surface soil solution toward the plant roots. This process of mass flow caused by leaf transpiration explains how most plant nutrients (98 percent) move from the soil to the root surface.

Detailed explanation-2: -Essentially all of the water used by land plants is absorbed from the soil by roots. A root system consists of a complex network of individual roots that vary in age along their length. Roots grow from their tips and initially produce thin and non-woody fine roots.

Detailed explanation-3: -This process is mediated by root hairs, which are extensions of the root epidermal tissue that increase the surface area of the root, greatly contributing to the absorption of water and minerals. Root hairs absorb ions that are dissolved in the water in soil.
