Question

Which structure protects the plant body against the invasion of parasites? How?

Answer 1

Epidermis provides protection to plants against the invasion of parasites. It forms an outer covering of plant organs which remains in direct contact with the environment. This epidermis is further covered by a layer of fatty substance called cuticle. The epidermis is interrupted only at regions where stomata are present. Anything that enters the plant, has to first cross this epidermal layer.
