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
Solution:
The correct answer is 'A- (iv), B-(i), C-(iii), D - (ii)
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, seedless grapes, watermelon
Ovule: contains embryo sac with the 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.
