Difference between Active and Passive Water Absorption – Comparison Table


Active vs Passive Absorption of Water

Active vs Passive Water Absorption
(Difference between Active and Passive Absorption of Water in Plants)

Plants absorb water along with minerals from the soil through root by a process called ‘absorption of water’. Based on the involvement of metabolic energy, the water absorption process in plants may be of two types – (1) Active absorption and (2) Passive absorption.

Active absorption: It is the absorption of water, usually against the concentration gradient, by the utilization of metabolic energy (energy from ATP).

Passive absorption: Absorption of water without the utilization of metabolic energy.

Difference between Diffusion and Osmosis: A Comparison Table


Difference between Osmosis and Diffusion

Diffusion vs Osmosis
(Difference between Diffusion and Osmosis)

Diffusion and Osmosis are the two methods in membrane transport by which the movement of materials in and out of the cell takes places.

Diffusion: Diffusion is the movement of particles from a region of higher concentration to a region of lower concentration. Example: When a scent-bottle is opened in a room, quickly the fragrance will spread to the entire room by diffusion of the molecules through the air.

Diffusion Example

Osmosis: Osmosis is a type of diffusion in which the solvent molecules move into the solution through a semi-permeable membrane. Example: Plasmolysis of a cell when it is placed in a sugar or salt solution.
