Answer 1

Correct choice is (d) Endodermis are also called as wax sheath as they are rich in waxy materials

Best explanation: Epidermis is covered with a thin layer of cuticle and it bears few stomata and trichomes. The hypodermis is made of collenchymatous cells and is present just below the epidermis. Cortex is made of parenchymatic cells with conspicuous intercellular spaces. Endodermis of a dicot stem is also called as starch sheath as they are rich in waxy materials.
