Cell Division
Learning Objective: I can describe the process of cell division
Learning Experiences: By researching cell division, I can explain its role in growth
and repair and can discuss how some cells can be used therapeutically- SCN4-13a
This activity asks pupils to work either as individuals, in pairs or alternatively in
small groups to place the stages of cell division in the correct order and with their
corresponding description.
Activity 1 - Cut out and match up the stages of mitosis diagrams with the
correct definition for each stage
Cell
Membrane
divides
There are no
chromosomes
visible
2 identical
daughter
cells are
formed
Chromosomes
appear in the
nucleus of the
cell
Chromosomes
are moved to
the equator by
spindle fibres
Chromosomes
separate to form 2
sister chromatids,
pulled to opposite
ends of the poles by
spindle fibres
Activity 2 – Classroom True and False
Print out stick the accompanying ‘True’ and ‘False’ cards on opposite walls of
your classroom. Then read out the statements below and get pupils to move
to the side of the classroom which they think represents the correct answer.
Alternatively, get pupils to work individually, in pairs or small groups and hold
up the true/false cards to represent their answer to the question.
1. Single Celled organisms use cell division for growth (F – Single celled
organisms use cell division for reproduction. This statement is true of
multicellular organisms)
2. Cell division is a means in which the number of cells in an organism
increases (T)
3. The cytoplasm controls the cell’s activities (F – Nucleus)
4. The nucleus of the cell carries chromosomes that are essential in growth
and development (T)
5. A chromosome is made up of two halves, each half is called a chromatid (T)
6. Chromatids are joined by a centrifuge (F – Centromere)
7. Human Beings have 46 chromosomes, or 23 pairs (T)
8. After cell division, 2 daughter cells are formed (T)
9. After cell division, one cell has half the number of cells as the original cell (F
– both cells have the same number of cells – this is known as the
chromosome complement)
10. Chromosomes are made from DNA Molecules (T)
11. A gene is a short section of DNA (T)
12. Individual genes code for specific proteins by specifying the order in which
they should be built using amino acids (T)
