The following points highlight the three important theories of water translocation. The theories are: 1. Capillarity 2. Root Pressure 3. Cohesion Theory. Water Translocation: Theory # 1. Capillarity: Question arises, can the water be raised to the top of such trees by capillarity? Such a rise of water in small tubes comes about because of the adhesion between water molecules [...]
In this article we will discuss about the relationship between transpiration and absorption. Object: Demonstration of Relation between Transpiration and Absorption Requirements: A bottle with a side, tube, cork, a plant, oil, balance, etc. Experiment: Here, the apparatus must be completely filled up with water and air-tight. In the side marked tube of the apparatus some oil drops are being [...]
The upcoming discussion will update you about the difference between transpiration and evaporation. Difference # Transpiration: 1. Transpiration is loss of water from surface of living cells. 2. It is a physiological process. 3. Transpiration is controlled by the processes, such as osmotic potential and water potential. 4. It involves living tissues. 5. Light, carbon dioxide concentration, pH and hormones [...]
