A) cutin
B) stomata
C) lignin
D) suberin
Correct Answer: A
Solution :
[a] Cutin is protective, hydrophobic waxy covering produced by epidermal cells of leaves, young shoots and other aerial parts. It minimises the water loss through transpiration (with the help of stomata) and also reduces pathogen entry. Lignin hardens the cell wall and provides flexibilty, tensile and compressional strength to the cell wall. Suberin is present in cork cells and makes the cell impervious to water.
