Plants absorb water through their entire surface – roots, stems, and leaves. However, the majority of water is absorbed by root hairs. i) The root system present in higher plants, in normal condition, acts as…

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 source of soil water. The soil water may be of…

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. It is not common among trees of the Temperate Zone…

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 from it’s cellulose wall when placed in a hypertonic solution.…

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 (T.P.). It is defined as the amount of pressure inside…

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 pressure deficit is the reduction in diffusion pressure of the…

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 passive movement of particles from a region in which they…

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 is the pressure created by water moving across a membrane…

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, allowing some substances to pass into the cell and blocking…

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 solution: Solution is of three types comparing with the concentration…
