Here is an experiment to demonstrate osmosis in potatoes with the help of suitable diagram. Materials Required: 1. Potato tuber 2. Petri dish, sugar solution, eosin solution, scalpel, pin etc. Procedure: 1. Take a large potato tuber and then remove the skin, also slice off portions from all sides to give it the shape of a flat rectangle. 2. Scoop [...]
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 [...]
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 [...]
