Question

Study the table given below and select the correct option from the following.

	List-I		List-II
A	Bryophyllum	I	Cuticle is absent
B	Nelumbo	II	High rate of transpiration
C	Pistia	III	Water is stored in the form of mucilage
D	Potamogeton	IV	Rhizome stem
		V	Balancing roots have root pockets in place of root caps

• A. (A)- (III), (B)- (IV), (C)- (V), (D)- (I)
• B. (A)- (V), (B)- (III), (C)- (II), (D)- (IV)
• C. (A)- (II), (B)- (IV), (C)- (I), (D)- (V)
• D. (A)- (I), (B)- (V), (C)- (II), (D)- (III)

Answer 1

The correct option is A (A)- (III), (B)- (IV), (C)- (V), (D)- (I)

• Bryophyllum is drought avoiding fleshy xerophyte that has succulent leaves due to the development of water-storing parenchymatous tissue to store water in the form of mucilage.
• Modification of Nelumbo stem into rhizome grows vertically upward and helps the leaves to float on the water surface.
  
• The root cap is a parenchymatous, cap-like multicellular structure that covers the root apical meristem and secretes mucilage to lubricate the path of the root in the soil. Being an aquatic plant, Pistia does not require a root cap which in turn is replaced by root pockets in the plant.
  
• Cuticle serves as a protective covering and reduces water loss; being an aquatic plant, Potamogeton does not require water-saving strategies and hence lacks a cuticle.
  

Therefore, the correct answer is option A.
