Question

what is transpiration

Answer 1

 In actively growing plants, water is continuously evaporating from the surface of leaf cells exposed to air. This water is replaced by additional absorption of water from the soil. Liquid water extends through the plant from the soil water to the leaf surface where it is converted from a liquid into a gas through the process of evaporation. The cohesive properties of water (hydrogen bonding between adjacent water molecules) allow the column of water to be ‘pulled’ up through the plant as water molecules are evaporating at the surfaces of leaf cells. This is called transpiration

Answer 2

it is the process in which plants secrete the excess water present in them by the pores in the leaves.ex_-dew on leaves in winter season.

hope this helps.
