Slide 1 - Slide

What do you remember about mitosis?

Slide 2 - Open question

Slide 3 - Video

Please order the four stages of Mitosis!
Prophase!
Metaphase!
Anaphase!
Telophase!
InterPhase!

Slide 4 - Drag question

What happens during prophase?

Slide 5 - Slide

  • Chromatin is condensed into chromosomes
  • The nuclear envelope breaks down and disappears
  • Spindle fibers form from centrioles in animal cells
What happens during prophase?

Slide 6 - Slide

What about during metaphase?

Slide 7 - Slide

  • Spindle fibers attach to chromosomes
  • Sister chromatids line up at the midline of the cell
What about during metaphase?

Slide 8 - Slide

So now whats going on in anaphase?

Slide 9 - Slide

  • Sister chromatids at the midline are pulled apart and move to each end of the cell
  • Each half of the cell now has a complete, identical set of chromosomes
So now whats going on in anaphase?

Slide 10 - Slide

Last but not least, how about telophase?

Slide 11 - Slide

  • Spindle fibers break down
  • A new nuclear envelope begins to form around each half of the cell
  • Chromosomes begin to "de-condense" back into chromatin
Last but not least, how about telophase?

Slide 12 - Slide

What happens next?

Slide 13 - Slide

  • Though not technically part of mitosis, it's still important.
  • This is the final stage of cell division, where the parent cell fully splits into two different cells
  • In plants a hard plate forms between the two cells called the "cell plate" which then gets replaced by a plasma membrane and cellulose cell wall.
  • In animals the cell pinches in and splits along the "cleavage furrow" formed in the middle of the cell.
What about cytokinesis!

Slide 14 - Slide

"cyto" - "kinesis"
Cyto means cell
Kinesis means movement
Cytokinesis is the movement of the new cells  apart from each other
Remembering Cytokinesis...

Slide 15 - Slide

Slide 16 - Slide

What phase of mitosis do these images show?
Prophase!
Metaphase!

Anaphase!
Telophase!

Slide 18 - Video

00:22
Look at how the chromosomes are arranged at this point. What stage of mitosis is this?
A
Metaphase
B
Prophase
C
Anaphase
D
Telophase

Slide 19 - Quiz

00:35
A hard cell plate formed in the middle of this cell after mitosis. What type of cell did we just watch divide?
A
Plant cell!
B
Animal Cell!

Slide 20 - Quiz

00:45
The cell in the video just underwent anaphase, how do you know this?
A
The cell split into two, distinct cells
B
The chromosomes pulled "away" from each other
C
The chromosomes arranged themselves on the equator of the cell
D
The cell's DNA was just replicated
