Present cohesion-tension-transpiration pull model of water transport.

Cohesion-tension-transpiration pull model explain that water is mainly 'pulled' through the plant.

Describe transpiration pull model of water transport in plants. What are the factors influencing transpiration? How is it useful to plants?

Describe : Transpiration Pull.

Explain water transport in porifera.

A heavy cart is pulled by a constant force F along a horizontal track with the help of a rope that passes over a fixed pulley, as shown in the figure. Assume the tension in the rope and the frictional forces on the cart remain constant and consider motion of the cart until it reaches vertically below the pulley. As the cart moves to the right, its acceleration

The sap in trees , which consists mainly of water in summer , rises in a system of capillaries of radius r=2.5xx10^(-5)m .The surface tension of sap is T=7.28xx10^(-2)Nm^(-1) and the angle of contact is 0^(@) .Does surface tension alone account for the supply of water to the top of all trees ?

An ability to resist a pulling force of water (tensile strength) is depends upon

What role is played by Root pressure in transport of water in plants ?

The level of water in the sea rises and falls due to the gravitational pull of the moon on the spinning earth.
