The plants absorb water and soluble mineral salts from the soil by their root system. This function of absorption is facilitated by the unicellular root hairs present on the roots. These unicellular root hairs enter in the interspaces of the soil particles, irregularly. These root hairs absorb the water found in the form of thin films around these soil particles. [...]
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 [...]
