Hygroscopy is the ability of a substance to attract and hold water molecules from the surrounding environment through either absorption or adsorption with the absorbing or adsorbing material becoming physically 'changed,' somewhat: by an increase in volume, stickiness, or other physical characteristic of the material as water molecules become 'suspended' between the material's molecules in the process. While some similar forces are at work here, it is different from capillary attraction, a process where glass or other 'solid' substances attract water, but are not changed in the process, e.g. water molecules becoming suspended between the glass molecules.

Zinc chloride and calcium chloride, as well as potassium hydroxide and sodium hydroxide (and many different salts) are so hygroscopic that they readily dissolve in the water they absorb: this property is called deliquescence (see below). Sulfuric acid is not only hygroscopic in high concentrated form, its solutions are hygroscopic down to concentrations of 10p Vol-% or below. More commonly, a hygroscopic material will tend to become damp and cake when exposed to moist air (such as salt in salt shakers during humid weather).

Deliquescent materials are substances (mostly salts) that have a strong affinity for moisture and will absorb relatively large amounts of water from the atmosphere if exposed to it, forming a liquid solution. Deliquescent salts include calcium sulfate, calcium chloride, magnesium chloride, zinc chloride, potassium carbonate, potassium phosphate, carnallite, ferric ammonium citrate, potassium hydroxide and sodium hydroxide. Owing to their very high affinity for water, these substances are often used as desiccants, which is also an application for concentrated sulfuric and phosphoric acids. These compounds are used in the chemical industry to remove the water produced by chemical reactions.[citation needed]

Plants absorb water from their root hairs on the root and send it to the other parts of the organism for food and growth enrichment. This process involves the unidirectional flow of water from roots to shoots against gravitational pull. If the roots of a plant are cut and the plant is dipped in water the plant still absorbs the water, this pull is mainly caused due to a force named transpiration pull. This is the most accepted answer for this question since the answer still remains a mystery and is controversial. Note: There are comments associated with this question.
