Solution

The branches of trees move and bend freely in wind because the branches of the tress have collenchyma cells. Collenchyma is a very flexible tissue. It gives mechanical strength and support to the plant body. It also provides elasticity to plants causing it to bend when the wind velocity is high without breaking the branch.
