This is a PowerPoint explaining mitosis. It contains 16 slides and is good for studying, revision or just to get a better general understanding of Mitosis. It is on the IEB standard and I would recommend this for Grade 10, but it would also help other grades(9 and 11) to increase their knowledge on...
List the 5 phases of Mitosis in the correct order.
Answer: Interphase, Prophase, Metaphase, Anaphase and Telophase.
2.
What is Mitosis responsible for?

3.
List the 4 different factors involved in causing cancer.
Answer: 1.) Biological or internal factors
2.) Environmental exposure
3.) Occupational risk factors
4,) Life-style related factors
4.
Explain Interphase?
Answer: 1.)Occurs when the nucleus is not in the process of cell division.
2.) The cell is fully developed and ready to divide
3.)The nucleus consists of the nuclear membrane, nuclear plasm, nucleoli and the chromatin network.
4) In anticipation of prophase, the DNA in each chromosome replicates itself
5.
Explain Prophase
Answer: 1.)Chromosomes separate and
undergo a shortening and
thickening.
2.) Each chromosome becomes
longitudinally split to show
chromatids attached to a point
called a centromere.
3.) A structure called a spindle begins
to develop at the opposite poles of
the nucleus. (fibre-like processes
growing across the centre of the
cell).
4.)The nuclear membrane and
nucleolus disappears.
