The following points highlight the top ten properties of water molecules. The properties are: 1. Temperature and Physical State 2. Absorption and Dissipation of Heat 3. Melting and Vaporizing Water 4. Water as a Solvent 5. Cohesion and Adhesion 6. Nature of Cellular Water 7. Factors Affecting the Chemical Potential of Water 8. Water in the Soil 9. Entry of [...]
Some instances water absorption appears to take place through the mediation of forces which originate in the root itself. Such a process is called active water absorption. It is operative in the form of root pressure, bleeding and guttation. Root Pressure: Roots of plants absorb water from the soil. Water thus absorbed is exuded in the dead xylem ducts of [...]
In this article we will discuss about:- 1. Meaning of Ascent of Sap 2. Rate and Amount of Ascent of Sap 3. Theories. Meaning of Ascent of Sap: The upward movement of water from the root to the top of the plant is called as ascent of sap. Plants absorb water through the roots and transpire through leaves. The water [...]
