The main difference between diffusion and active transport is that diffusion is a passive transport method in which molecules move across the cell membrane through a concentration gradient whereas active transport requires cellular energy in order to transport molecules against the concentration gradient.

Passive transport doesn’t require energy (ATP), active transport does require energy. Passive transport moves molecules WITH the concentration gradient (high to low), while active transport moves molecules AGAINST the concentration gradient (Low to High).

Active cellular transportation (ACT) Unlike passive transport, which uses the kinetic energy and natural entropy of molecules moving down a gradient, active transport uses cellular energy to move them against a gradient, polar repulsion, or other resistance.

Medical Definition of imbibition : the action or process of assimilating, taking into solution, or taking in liquid especially : the taking up of fluid by a colloidal system resulting in swelling. Other Words from imbibition. imbibe / im-​ˈbīb / verb imbibed; imbibing. More from Merriam-Webster on imbibition.

Imbibition is a type of diffusion where the water is absorbed by the solid particles called colloids, causing an enormous increase in volume. The solution is not formed in the process. In other words, water absorption by colloids is known as imbibition.

Imbibition is a seed’s or a plant’s absorption of water, a process that causes swelling in some plant cells and organs. Seeds undergo imbibitionswelling when exposed to water. The process of imbibition is important to the plant since it encourages seedlings to emerge out of the soil and establish themselves.

Imbibition is a process in which water is absorbed by solids-colloids causing them to enormously increase in volume. The classical examples of imbibition are absorption of water by seeds and dry wood.

Which of the following is an example of imbibition? (a) Uptake of water by root hair (b) Exchange of gases in stomata (c) Swelling of seed when put in soil (d) Opening of stomata. Answer: Imbibition is a type of diffusionprocess along the concentration gradient enabling the solid to absorb water andincrease in volume.

: shrinking of the cytoplasm away from the wall of a living cell due to outward osmotic flow of water.
