Osmotic pressure can be measured in various ways which are described below:- 1. Mechanical Methods 2. Biological Methods 3. Physical Methods. 1. Mechanical Methods: (i) By Putting Weights: The simplest way is to apply adequate pressure (i.e., weight) upon the stronger solution to prevent any rise of volume. That pressure which is just needed to stop the increase of volume [...]
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 [...]
