Question

10 points on plant mitosis​

Answer 1

Answer:

Mitosis is a continuum of changes but biologists like break down the stages of mitosis into four main stages, prophase, metaphase, anaphase and telophase.

The focus in this class is on an understanding of the process and not memorization of phases.

The only phase name you will need to remember is metaphase.

In mitosis the nuclear membrane is broken down, spindle fibres (microtubules) attach to the chromatids at the centromere and pull apart the chromatids.

When the chromatids reach separate ends of the cells the spindle fibres disintegrate and a nuclear membrane rebuilds around the chromosomes making two nuclei.

Each nucleus is identical to the original nucleus as it was in G1
