In this article we will discuss about the classification of plant tissues based on development. Tissues are generally classified on the basis of development and the types of constituent cell — a brief account of which is as follows. Classification of tissues based on development: (a) Meristematic Tissue: Meristematic tissues can be defined as a group of cells which have [...]
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 [...]
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 [...]
