Transcript
Mitotic cell cycle – arrange the diagrams of the stages of mitosis into the correct
sequence; match the statements with each stage.
Telophase. New membranes form around the
daughter nuclei while the chromosomes disperse
and are no longer visible under the light
microscope.
Interphase. The cell is engaged in metabolic
activity and performing its duty as part of a tissue.
The DNA duplicates during interphase to prepare
for mitosis (the next four phases that lead up to
and include nuclear division). Chromosomes are
not clearly visible in the nucleus, although the
nucleolus may be visible.
Metaphase. The chromosomes align along the
middle of the cell nucleus. This line is referred to
as the metaphase plate. This organisation helps
to ensure that in the next phase, when the
chromosomes are separated, each new nucleus
will receive one copy of each chromosome.
Cytokinesis. The division of the cytoplasm into
two.
Prophase. Chromatin in the nucleus begins to
condense and becomes visible in the light
microscope as chromosomes. The nuclear
membrane dissolves. Microtubules attach at the
centromeres and the chromosomes begin
moving.
Completion of division. Two new cells are
produced.
Anaphase. The paired chromosomes separate at
the centromeres and move to opposite sides of
the cell.
