Hair forms a protective barrier
Your question makes no sense. Only human children can be "adopted", root hairs cannot be adopted. Further, root hairs are plural so it should be "their function" not "its function".
Rhizoids are unicellular absorbtive hairs and their function is absorption
It works as a filter for particles in the air.
The function of root hairs is to absorb water and nutrients from the soil. If the root hairs have a cuticle covering, it will prevent the free absorption of water and nutrients from the soil.
the function known as elongation
allows the exit of hairs through the epidermal surface
if it helps i think the hairs are called cilia and works together with mucus :) hope this helps
They are sometimes called nose hairs. Their function is to filter small particles like dust and pollen from going deeper into the airway.
Depends on each animal. On humans it seems they have no function except the head hair which has a protective function against heat and cold on the head.
to prevent dust to come inside our nose
they do nothing. They are there because you have hair all over your body.
The submerged leaf filaments are covered with brown hairs which function as roots for water and nutrients absorption. Sporocarps(i) are borne on submerged leaf filaments.
