Mitosis

True or False: Mitosis occurs in prokaryotic and eukaryotic cells

• True

• False

Check all that apply: Why does mitosis occur

• For organisms to grow

• To replace damaged cells

• To replace old cells

• To create gametes

Which phase does the cell spend most of its time in?

• Interphase

• Prophase

• Metaphase

• Anaphase

• Telophase

DNA is copied during ​ (a)   , which occurs in ​ (b)   If the cell passes the checkpoint at the end of the ​ (c)   , it will enter ​ (d)   .

• S-phase
• interphase.
• G2 phase
• mitosis

How many stages of mitosis are there?

• One

• Two

• Three

• Four

Match the following stage with its description

• Prophase

• Chromosomes line up at the equator

• Metaphase

• Spindle fibers continue to shorten and pull the sister chromatids apart

• Anaphase

• DNA condenses and spindle fibers attach

• Telophase

• Cleavage furrow forms, nucleus begins to reappear

When DNA is uncondensed, it is known as ​ (a)   . Once it is fully condensed, it is known as ​ (b)   . After chromosomes are replicated, they will pair with their identical match, known as the ​ (c)   .

• chromatin
• chromosomes
• sister chromatid

​ (a)   are produced by the ​ (b)   , which are located in the ​ (c)   area at the poles of the cell. The spindle fibers elongate and will attach at the ​ (d)   .

• spindle fibers
• centrioles
• centrosome
• kinetochore

Instead of a contractile ring, what forms in a plant cell during telophase and cytokinesis?
