Question

let's imagine a diploid plant cell.

a) draw the five stages of mitosis and meiosis assuming N=3

b) briefly explain each step of mitosis and meiosis.

Answer 1

Mitosis is 4 substages; prophase, metaphase, anaphase, and telophase

In prophase, chromatin network coil and seen as distinct long thread like structures and nuclear membrane gradually disappears.

In Metaphase, chromosomes align at metaphase plate facing opposite poles. Spindle fibres from opposite poles attach to centromeres. In late metaphase, centromere divides and stat separating.

Anaphase is marked by separation of chromosomes to the opposite poles.

In telophase, they uncoil and elongate to form thin chromosomes.
