Question

Write short notes on:

Root Pressure

Answer 1

• Root cells are in contact with water and minerals in the soil. 
• Water and minerals enter the cells of the root surface due to difference in concentration. As a result, these cells become turgid. 
• This is called root pressure. 
• Under the effect of this pressure, water and minerals reach the xylem of the roots and to reduce this difference in concentration, they are continuously pushed forward. 
• As a result of this continuous movement, a water column is formed, which is continuously pushed ahead. 
• This pressure, is sufficient to lift the water up in shrubs, small plants and small trees.
