Name: _________________________________________________ Date: _______________ Period: ________ Biology Notes: Mitosis Directions: Fill in the blanks as we cover the topic in the PowerPoint. What is Mitosis? • Mitosis: Cell division involving _________________________ (____________‐sex) cells • Involves only _______________________ cells • Form of _______________________ reproduction for some life (____________________ & protista, fungi) • End Result: __________ genetically _______________________ “_______________________ cells” The Cell Cycle • Defined: _______________________ set of events in the _______________________ of a cell 1) _______________________ – G1, _____, G2 2) _______________________ 3) _______________________ 4) _______________________ 5) _______________________ Interphase • Divided into _____ Stages: • G1 Stage – _______________________ function performed – Cell _______________________ – _______________________ created (replicated) • S Stage – _______________________ (DNA strands) _______________________ • G2 Stage – Cell _______________________ – _______________________ function performed Prophase • ________ Mitosis Stage • _______________________ (DNA strands) _______________________ into chromosomes • Nucleus _______________________ spilling the chromosomes • _______________________ fibers form Metaphase • ________ stage of mitosis • Spindle fibers _______________________ to _______________________ of each chromosome • Spindle fibers _______________________ the chromosomes to the cell’s _______________________ Anaphase • ________ stage of mitosis • Spindle fibers _______________________ apart the chromosomes – 1 _______________________ pulled to _______________________ direction Telophase • ________ stage of mitosis • Spindle fibers _______________________ • Chromatids _______________________ into _______________________ • _______________________ begins to _______________________ _______________________ telophase • _______________________ occurs (division of _______________________) • End result: ________ identical _______________________ cells Review 1) In order, name the 5 stages of the cell cycle: 1) _______________________________________ 2) _______________________________________ 3) _______________________________________ 4) _______________________________________ 5) _______________________________________ 2) During which interphase stage do organelles replicate? __________________________________________ 3) What do you call the division of the cell’s cytoplasm? ___________________________________________ 4) Which type of cells divide by mitosis? ________________________________________________________ 5) During which interphase stage is DNA created? ________________________________________________ 6) During which stage do spindle fibers form? ___________________________________________________ 7) During which stage are chromosomes aligned in the middle? _____________________________________ 8) During which stage are chromatids separated? ________________________________________________ 9) During which stage does the nucleus dissolve? _________________________________________________ 10) What is the result of mitosis?_______________________________________________________________ 11) Using the line provided, put the following pictures of the cell cycle in order from start (1) to finish (5), then label which stage of the cell cycle each is in:
