Question

Why do plants have rigid barks

Answer 1

Answer: Woody plants have a tough, waterproof outer layer of cork cells commonly known as bark, which further protects the plant from damage.

Answer 2

Bark is the outermost covering of a tree's trunk and branches, like a protective skin. Tree bark conserves water and also serves to protect the tree's essential living systems from environmental and situational dangers. These include temperature extremes, storms, attacks by animals, diseases, and insects.
