Hair - Plants

Hairs in plants grow from epidermal cells and are involved in transpiration. Some hairs can be found in plant roots and actively absorb water while others are capable of secretion. Sometimes a network of hairs on the outer layer of plants allow a reduced rate of transpiration, as water gets trapped between the plants and hairs, effectively reducing the water concentration difference between the plants internal Environment and its immediate external environment.
