Absorbtion, generally of water, and usually by plants.
Imbibition

Imbibition is the process where seeds absorb water to initiate germination. This process helps in softening the seed coat, triggering metabolic activities, and allowing the seedling to emerge from the seed.

Imbibition deals with the displacement of fluids primarily by colloidal structures. The degree of displacement is dependent on the matrix structure of the colloid and the mutual affinity with the liquid. Germination of plant seeds is a good example of imbibition, but doesn't deal with living cells directly. In living human cells, imbibition by definition has limited occurrence with the best example being a skin graft. The grafted skin takes in oxygen and nutrients by way of imbibition until normal vascular pathways can be established. Other transport methods involving membrane permeability are more pertinent to cellular structures within the human body. Hope this helps.

Agar does not exhibit syneresis (syneresis is the expulsion of liquid from a gel) but it can imbibe water (imbibition is the process of absorbing water). Agar is commonly used as a solidifying agent in microbiology and food industries due to its ability to absorb water and form a gel.
Imbibition in rubber can be observed when rubber swells or expands upon exposure to liquids, such as water or certain solvents. This process occurs as the liquid penetrates the porous structure of the rubber, causing it to absorb moisture and increase in volume. You can notice this effect by measuring the dimensions of the rubber before and after immersion in a liquid, where an increase in size indicates imbibition. Additionally, changes in physical properties, such as flexibility or hardness, may also be evident after the rubber has absorbed the liquid.
The first stage of plant germination is seed imbibition, which is when the seed absorbs water and swells up. This process begins the activation of enzymes that break down stored nutrients in the seed to provide energy for the germinating seedling.
Germination of the seed causes changes within the seed coat which allows for massive absorption of water via imbibition.
