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 [...]
The absorption of water by the root hair does not depend solely upon its osmotic concentration but also upon its osmotic potential which is equivalent to the difference between its osmotic potential and its pressure potential. If the root hair becomes fully turgid, in order that its osmotic pressure becomes zero, it will absorb no more water from the soil. [...]
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 [...]
