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)(A).
Wheat is an angiosperm plant. In this plant 8080 grains (seeds) are produced by fertilization between 8080 male and 8080 female gametes. 8080 male gametes therefore, pollen grains are produced by 2020 meiosis in microspore mother cells while 8080 female gametes therefore, megaspores are formed by 8080 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=10020+80=100.
So, the correct option is '100'.
So, the correct option is '4 Haploid cells'.
