Answer 1

Answer -

Option 1 is correct

Epidermis with thick cuticle

Answer 2

Answer:

(1) Epidermis with the thick cuticle in a Cycas leaf indicates its xerophytic nature.

The stem of the extinct gymnosperm Cycas, often known as the "sago palm," generates sago, a material that resembles starch. Cycads are xerophytic, making them drought-hardy and requiring little water.

The epidermis of leaves, new shoots, and other aerial plant organs without periderm is protected by a layer known as a plant cuticle. It is only produced by epidermal cells and is made up of wax-impregnated lipid and hydrocarbon polymers.
