Answer 1

Answer: (A)

Hair on the lower surface and waxy cuticle

• Leaves have a layer of waxy cuticle on their surface as it helps in preventing water loss due to excess transpiration. The leaves may also have hair on the lower surface which act as trichomes and protect the surface of the leaves.
• The epidermis of the leaves has minute pores called stomata through which gaseous exchange takes place.
• Endodermis and Casparian strips are present in the roots of the plants.

So, the correct answer is 'Hair on the lower surface and waxy cuticle'.
