Answer 2

Answer:

Plants absorb minerals and nutrients from the soil in liquid form through Osmosis so they have to absorb much water even to take up small quantities of these nutrients.The excess of water is of no use for the plant so it gets rid of it through transpiration, also evaporation of this excess water from the leaves has a cooling effect on the plant and protects it from scorching in summer that is why in summer there is relatively more transpiration than in winter .
