absorb water from the soil, the excess of water is given out
through this process.
(2) The greater the rate of transpiration the greater is the
rate of absorption of water from the soil
(3) As absorption helps in taking of organic salts from
soil, transpiration rate is more the rate of absorption of
inorganic salts from the soil is also high.
(4) Transpiration also helps in osmosis
(5) This process also helps in distributing water throughout
