प्रश्न
Water in the root enters due to ______.
पर्याय
The function of the root to absorb water.
difference in the concentration of ions between the root and the soil.
excess water present in the soil.
diffusion of water in the roots.
उत्तर
Water in the root enters due to The function of the root to absorb water.
Explanation:
The main job of a plant's root system is to take up water and vital nutrients from the soil. The root hairs, which are tiny extensions of the root cells that increase the surface area of the root for greater absorption, are responsible for this absorption. In order to create a concentration gradient that draws water into the root, the root cells actively transport ions and minerals from the soil into the root.
