Capillary water is held in the capillary pores (micro pores). Capillary water is retained on the soil particles by surface forces. It is held so strongly that gravity cannot remove it from the soil particles. The molecules of capillary water are free and mobile and are present in a liquid state. Due to this reason, it evaporates easily at ordinary temperature though it is held firmly by the soil particle; plant roots are able to absorb it. Capillary water is, therefore, known as available water. The capillary water is held between 1/3 and 31 atmosphere pressure.
Gravitational water occupies the larger soil pores (macro pores) and moves down readily under the force of gravity. Water in excess of the field capacity is termed gravitational water. Gravitational water is of no use to plants because it occupies the larger pores. It reduces aeration in the soil. Thus, its removal from soil is a requisite for optimum plant growth. Soil moisture tension at gravitational state is zero or less than 1/3 atmosphere.

What is the property of water to move upward against the gravitational force?
capillary
When the osmotic pressure in a capillary exceeds the blood pressure in the capillary what is the net movement of fluid?
water and waste will move in capillary . water and waste will move in capillary .
Capillary action occurs when water rises from the water table into?
The capillary fringe
What has greatest capillary action?
The narrower the bore of the tube ,the greater is the capillary action. For example :A sponge retains water (on being dipped in water)is due to capillary action.
What the hypothesis for the capillary action?
Capillary action will pull water up the stem to the flower and into the petals.
What types of bonds allow different water molecules to be attracted to one another and allows capillary action to occur?
These are hydrogen bonds between water molecules.
What is capillary action. Why is capillary action extremely important for plants?
Water uses capillary action to "climb" up plant vessels through cohesion and adhesion, which allows the water to be transported throughout the plant.
Is capillary action a product of adhesion?
The adhesive force of wetting liquids specially water is responsible for capillary action, the capillary action is not possible for Mercury.
Why is capillary action insufficient to move water through a plant?
Capillary action is not sufficient to lift water against gravity after certain height .
Capillary action affect the movement of water underground?
Capillary action forces water upward. So it takes the water from underground causing it to affect the movement of water under ground
What cohesive and adhesive forces draw water from the roots to the different parts of the plants?
Surface tension; Capillary action; and Turgor Pressure.
What property of water gives rise to capillary action?
Cohesion force among the molecules of water allows for capillary action in plants.
