Page 1: Mitosis lab ppt

What phase is the cell shown in? Interphase

What are the long and threadlike chromosomes in this stage called? Chromatin

What percentage of the cell cycle is spent in interphase?90%

Page 2: Mitosis lab ppt

What are the three parts of interphase called?

G1G2

Synthesis

What happens to the DNA during the synthesis stage? Duplication

Page 3: Mitosis lab ppt

Why do we duplicate the DNA during interphase?

So that the daughter cells have the same information as the mother cell!

Page 4: Mitosis lab ppt

What phase is the cell shown in? Prophase

The original and duplicate strands of DNA are called sister…. Chromatids

What disappears during prophase?

Nuclear membrane, nucleolus

Page 5: Mitosis lab ppt

What are the two organelles (circled in red) that migrated to opposite poles of the cell during prophase called? CentriolesWhat role do these organelles play in cell division? They form the spindle apparatus

Chromatids

Cell WallCytoplasm

Page 7: Mitosis lab ppt

What phase is the cell shown in? Metaphase

Where are the chromatids located during metaphase? Middle

What’s another name for the center or middle of the cell? Equator

Page 8: Mitosis lab ppt

What phase is the cell shown in? Anaphase

What attaches the chromatids to the spindle fibers? Centromere

Page 9: Mitosis lab ppt

What phase is the cell shown in? TelophaseWhat reappears in this phase?

Nuclear membrane, nucleolus

Cell plate

Page 10: Mitosis lab ppt

How does cytokinesis differ in this cell from the one shown in the previous slide?

Page 11: Mitosis lab ppt

What do we call the two cells formed from mitosis?

Daughter cells
