Question

branches of a tree move and bend freely in high wind velocity why?

Answer 1

THEY CAN BENT EASILY BECAUSE OF THE PRESENCE OF A SIMPLE PERMANENT TISSUE CALLED COLLENCHYMA

Answer 2

They can twist effortlessly in light of the nearness of a basic changeless tissue called collenchyma. One of the elements of the collenchyma is to bolster simple bowing. Accordingly, trees move openly in high wind speed.

Branches of the tree are cantilevers and the wind speed applies a disperse force(load), so as per hypothesis of structures they bend and move.
