Physiology of Plant

Plants absorb water through their entire surface – roots, stems, and leaves. However, the majority of water is absorbed by root hairs. i) The root…

In higher plants, the main and only source of water is soil water. The rain water is soil water. The rain water is the only…

Root Pressure The total turgor pressure of the cortex tissue as a result of which water enters the xylem vessels through endodermis called root pressure.…

Plasmolysis: Plasmolysis is the process by which cells lose water in a hypertonic solution. Plasmolysis may be defined as the shrinkage of cell protoplasm away…

Turgor pressure (T.P.) and Wall pressure (W.P.) Turgor Pressure: The pressure that is exerted on the cell wall duel to turgidity is called Turgor pressure…

Diffusion pressure deficit: Diffusion pressure expresses the potential aptitude to diffuse from an area of the greatest concentration to an area of lesser concentration. Diffusion…

Diffusion: When a substance of it’s area of higher concentration diffuses to the area of lower concentration is known as diffusion. It is the net…

Osmotic pressure: Osmotic pressure can be defined as the pressure required to stop completely the movement of the solvent through the semi-permeable membrane. Osmotic pressure…

Cell membrane is the thin layer of protein and fat that surrounds the cell, but is inside the cell wall. The cell membrane is semipermeable,…

A homogenous mixture of more than one substance in which the attachment of the component can be changed is said to be solution. Types of…
