Explanation
A. Anaphase – Contraction of spindle fibres takes place, division of centromere occurs, daughter chromosomes move towards the poles.
B. Prophase – condensation of chromosomes occur. Chromosomes thick, short.
C .Metaphase – Metaphasic or equatorial plate is formed.
D. Telophase – Decondensation of chromosomes takes place. Chromosome elongated and their length increases.
The correct answer is (A).
Wheat is an angiosperm plant. In this plant 80 grains (seeds) are produced by fertilization between 80 male and 80 female gametes. 80 male gametes therefore, pollen grains are produced by 20 meiosis in microspore mother cells while 80 female gametes therefore, megaspores are formed by 80 meiosis in megaspores mother cells because in angiosperm plants, after meiotic division in single megaspore mother cell, four megaspores are formed but only one megaspore is survived and other three get degenerated. Thus total meiotic divisions are 20+80=100.
So, the correct option is '100'.
So, the correct option is '4 Haploid cells'.
