1. What happens to
chromosomes in prophase?
2. What happens to
chromosomes in
metaphase?
Brain Warm-up
• What do HISTONE hands look
like?
Brain Warm-up
• What is the difference
between chromosomes, sister
chromatids, and homologous
chromosomes?
What is IPMATC?
• Share the names of the phases
of mitosis IN ORDER in your
groups
Interphase
Mitosis - PROPHASE
Mitosis - METAPHASE
Mitosis - ANAPHASE
Mitosis - TELOPHASE
Cytokinesis
Brain Warm-up
• Finger Mitosis Dance!
Mitosis
•
ON YOUR OWN: 15 min
• Label the phases on the mitosis
diagram (cytokinesis is not included)
• Get your labels checked off
• Cut the phases out and paste them on
a blank sheet of paper/your notebook
IN ORDER
• Color the chromosomes
• Write what is happening in each
phase
Onion Mitosis
• What does mitosis look like in
real cells?
Onion Mitosis
What does mitosis look like in real cells?
Onion Mitosis
What does mitosis look like in real cells?
Prophase can be
distinguished from
interphase because the
DNA has noticeably
thickened.
Onion Mitosis
What does mitosis look like in real cells?
Metaphase can be
distinguished from
prophase because the
chromosomes are lined
up in the middle of the
cell.
Onion Mitosis
What does mitosis look like in real cells?
Anaphase can be
distinguished from
metaphase because the
chromosomes are
being pulled apart.

Be prepared to decipher the phase
of a real cell
Identifying Phases of Mitosis
• This is VERY IMPORTANT
• The lab tomorrow will require
you to identify and count cells
in the phases of mitosis
• PLEASE PAY ATTENTION
• You will be called on to identify
at least one cell
