Question

Which mechanism plays an important role in transportation of water in plants?

1. During day time

2. At night.

Answer 1

1. During day time suction pressure creates by transpiration (evaporation of water) helps in absorption and upward movement of water and minerals dissolved in it from roots to the leaves, us to the top of the plant.

2. At night, the effect of root pressure [created by movement of water from the soil to the xylem of roots] in transport of water is more important.
