ANSWERS
MITOSIS AND MEIOSIS Ctd.
Complete the following chart to show the comparisons between mitosis and meiosis.
MITOSIS
MEIOSIS
Daughter cells are exact replicas of
the parent cell.
Daughter cells are not
identical to the parent cell.
Two daughter cells are
produced from one parent
cell.
Four daughter cells are produced
from one parent cell.
The number of chromosomes
present in the daughter cells is the
same as in the parent cell.
The number of chromosomes
in the daughter cells is half
the number in the parent.

The following set of diagrams represents the successive stages in the process of meiosis.
In the empty boxes provided, fill in brief descriptions of what is happening at that stage.
The parent cell containing
one pair of chromosomes
The chromosomes
replicate forming
identical chromatids
The chromosome pairs
are pulled to opposite
ends of the cell and a
membrane forms
The cell divides into two
daughter cells
The chromatids in each
cell are pulled apart
The cytoplasm divides
and new membrane is
formed
Four daughter cells produced
which have half the number
of chromosomes as the
parent cell
