• A. A-(v), B-(iv), C-(iii), D-(ii), E-(i)
• B. A-(ii), B-(v), C-(iii), D-(i), E-(iv)
• C. A-(ii), B-(v), C-(i), D-(iii), E-(iv)
• D. A-(iii), B-(v), C-(iv), D-(i), E-(ii)

Answer 1

Answer: (C)

A-(ii), B-(v), C-(i), D-(iii), E-(iv)

• Thorns represent the modification of an axillary shoot system in which the leaves are reduced. Their main function is to protect the plant from herbivores,example are Citrus.
• Phylloclades are the flat photosynthetic shoots which are the modified branches.
• Vegetative propagation is a method of reproduction in plants by the fragments or cutting of parent plant which further produce the more plants or clones. Runner is also type of vegetative reproduction. Strawberry plant has a stolon, which is also called a runner.
• Stilt roots are the adventurous roots that help in supporting the plant body. They are also known as support roots. They develop from the base nodes of the main stem and they always grow obliquely., e.g, are Maize, sugarcane.
• Haustorium are the highly modified stem stem or root of a parasitic plant. It penetrates the host tissues and then absorbs nutrients and water.
• So,the correct answer is " A - (ii), B - (v), C - (i), D - (iii), E - (iv) ".
