The below mentioned article provides biology notes on Water Absorption from Soil. Soil is the upper weathered, humus, mineral water and air containing layer of the earth’s crust which supports plant life. Water is an important constituent of soil because all land plants depend upon it for their requirement of water. Deep in the soil and above the imperÂmeable stratum, [...]
Let us make in-depth study of the organ, mechanism, factors and methods of water absorption. Absorption of water and nutrient material is carried on only by the younger portions of a root, near its tip (See Fig. 2.2). The very tip itself is usually covered with a sheathing root cap of cells which protects the delicate underlying tissues as the [...]
The following points highlight the four soil factors influencing the water absorption rate by roots. Factor # 1. Concentration of the External Soil Solution: Absorption of water, in general, depend upon the difference between the osmotic concentration in the cell sap and the external soil solution. Thus an increase in the concentration of the external water medium, must reduce the [...]
