	Group A		Group B
A.	Aleurone layer	(i).	Without fertilisation
B.	Parthenocarpic fruit	(ii).	Nutrition
C.	Ovule	(iii).	Double fertilisation
D.	Endosperm	(iv).	Seed

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

Answer 1

Answer: (B)

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

Aleurone layer - a layer of protein storage cells, present in cereal, maize seed, and is a form of reserved food material.

Parthenocarpic fruit - when the ovary is stimulated to form fruit without fertilization then it is a parthenocarpic fruit

Example, seed less grapes, water melon

Ovule: contains embryo sac with egg cell, synergids, polar nuclei and antipodal cells. In angiosperms the pollen tube releases two male gametes, of which one fuses with the egg cell to form the zygote while the other fuses with polar nuclei to form triploid PEN

Endosperm- PEN develops into endosperm which provides nutrients to the developing embryo.

So, the correct answer is 'A- (iv), B-(i), C-(iii), D - (ii)'
