Question

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

Answer 1

The dermal tissue of plants and hard cuticle covering protect the plant body from invasion of parasites and other harmful agents.

Answer 2

Answer:

• The structure which protects the body of plant against the ‘invasion of parasites’ is the epidermis.
• The epidermis is the outermost thick protective layer in plants. It acts as the “first line of defence” against the invading parasites.
• The epidermis cells that are present in the aerial parts of the plants are covered with a waxy cuticle which prevents both water loss and microbial entry.
• The cuticle prevents the pathogenic parasites to come into direct contact with the plant cells and thus limits infection.
• Epidermis also protects the plant from various physical or chemical influences and other environmental stressors.
