Question

Why does cork act as a protective tissue

Answer 1

Cork is the tissue on the outer periphery of a tree. Usually it is on a old tree. It is also called the bark. It protects the tissue inside.

Cork tissue are dead actually. They are very very closely packed. So there are no gaps between the cells. External harmful organisms cannot enter inside.

Cork forms several layers on the outside. There is a deposit of suberin on their cell walls. So water or air does not penetrate through that.

Thus water or other important nutrients cannot escape the tree. Harmful things from outside will not enter the tree. Also any physical damage from outside does not harm internal parts easily. The bark is strong physically and withstands pressure from outside.

Cork acts as a protective tissue because its cells are dead and compactly arranged without intercellular spaces. They have deposition of suberin on the walls that make them impervious to gases and water.
