Answer 2

Water in the roots move by two pathways. Plants absorb water through the entire surface - roots, stems and leaves. However, mainly the water is absorbed by roots. The area of young roots where most absorption takes place is the root hair zone. The root hairs are delicate structures which get continuously replaced by new ones at an average rate of 100 millions per day. 

Water in the roots move by two pathways. They can be classified as1) Apoplast pathway2) Symplast pathway
