mitosis - Macmillan Academy
Starter
On a post it draw a circle
This is to represent the cell cycle
Shade the % of it that you think is taken up by mitosis
Stick onto the white board
How did you do?
Learning objectives
Recall the stages in the mitotic cell cycle
Describe the key features of each stage of mitosis
Identify the stage of mitosis in electron micrographs
I pee on the mat c
Interphase
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
Which of these are the stages of mitosis?

Make your own mnemonic
Understand what the question is asking
What are the stages of the mitotic cell cycle?
What are the stages of mitosis?
Specification point
Need to look at the following things at each stage of mitosis
Chromosomes
Nuclear envelope
Cell membrane
Centrioles
Main task
Create a poster of the stages in order commenting on each of the key features from the spec
A picture is needed for each stage
Add cytokinesis in another colour so it stands out as coming after mitosis (not a stage of)
Peer assessment
Look at each slide and assess how people did
Fill in your feedback sheet
Prophase
Chromosomes becoming visible
Nuclear envelope
No major point still there
Cell membrane
Nothing happening
Centrioles
Starting to position themselves and start forming the spindle
Metaphase
Chromosomes
Line up across the equator
Nuclear envelope
Disappears
Cell membrane
Nothing happening
Centrioles
At the poles of the cell and spindle complete
Anaphase
Chromosomes
Chromatids pulled apart
Nuclear envelope
Still missing
Cell membrane
Nothing happening
Centrioles
Shortening spindle moving the chromatids
Telophase
Chromosomes
Reach the poles of the cell
Start to decondense and become less visble
Nuclear envelope
One forms around each set of chromosomes
Cell membrane
Nothing happening
Centrioles
Returned to normal
Electron micrographs
Look at the micrographs
Identify cells at different stages of mitosis – you probably won’t spot them all
Matching mitosis activity from
Friday afternoon Biology
In groups – 5 groups in total
When you have decided get it checked with the master sheet
Question to complete on paper and hand in for marking
