Question

Assertion : In dicot leaf, epidermis covers both the upper surface (adaxial epidermis) and lower surface (abaxial epidermis).

• D. If both assertion and reason are false

Answer 1

Answer: (C)

Most of the dicotyledonous leaves are dorsiventral. Epidermis covers both the upper and lower surfaces of the leaf. Both upper and lower epidermis consist of rectangular parenchymatous cells. The abaxial epidermis generally bears more stomata than adaxial epidermis. Sometimes adaxial epidermis may even lack stomata.
