Here is an experiment to demonstrate osmotic pressure in plant tissues. Theory: The phenomenon 'Osmosis' refers to the movement of water from a solution of higher water potential to one of lower water potential, across a differentially permeable membrane which separates the two solutions. The magnitude of osmotic forces in plant cells and tissues can be estimated in terms of [...]
Here is an experiment to demonstrate water potential of plant tissues. Theory: The chemical potential of water is referred to as water potential Ψ (psi) and is a property of great importance to an understanding of water movement in the plant-soil-air system. Water potential (Ψ) is usually expressed in terms of pressure (e.g. bars). Absolute values of chemical potential of [...]
List of top two experiments on Imbibition in Plants: 1. Effect of Seed Coat on Water Absorption by Dry Seeds 2. Effect of the Nature of Seed on Water Absorption. Experiment # 1. Effect of Seed Coat on Water Absorption by Dry Seeds: The process 'imbibition' is considered as a special type of diffusion since the net movement of water [...]
