Q1. The following diagrams represent cells from a diploid organism with (2n=4) undergoing different stages of a division designated as (I,II, III,IV): 

a.      for each of the divisions, describe and conclude the type of division and its specific stage. (1.5 Marks each)

Answer 1

prophase, metaphase, anaphase and telophase.1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin
