Question

Give the reasons to the following: (AS 1)
- Xylem is a conductive tissue
- Epidermis gives protection

Answer 1

Xylem is a conductive tissue: Xylem is a complex vascular tissue, it consists of elements like tracheids and vessels that are dead and conducts water and minerals from the roots to the leaves

Thus, xylem is a conductive tissue.

Epidermis is the outermost tissue layer covering all the organs in a plant. These are closely placed cells and are impervious to water and micro-organisms. They may undergo modifications to form trichomes, may be covered with wax or cuticle to prevent desiccation.

So, epidermis gives protection.
