Young stems (twigs) bend but do not break. Why?

Text Solution

Verified by Experts

In young stems (twigs), the tissue that gives flexibility and tensile strength to the plant is collenchyma. It is a living tissue with thickened corners made up of cellulose which provide mechanical support to young plant, hence the stems bend but do not break.
