Hello

Please help me with the following

What is suction force in plants and how does transpiration help to produce it?

Answer 1

The suctional force in plant is due to transpiration,This force helps the plant to collect vital minerals from the soil.


Due to evaporation of water from the cells present on the surface of the leaves (transpiration) a vacuum space is created. To fill that vacuum water droplets from the other cells rush inside. This rush of water towards the vacuum creates a mechanical force that enables to pull up water absorbed by the roots through the stems.
