Mitosis    

Nucleus-­‐___________________________  the  cell.    Nucleolus-­‐    Makes  _______________________________  and  maybe  more  than    _______  in  the  nucleus.    Chromosomes-­‐    Determines  what  ________________________  you  will  have  and                          passes  information  from  ____________________  to  ___________________________    Cell  Membrane-­‐  Gives  the  cell  ______________________  and  controls                          what  moves  ___________  and  _________________  of  the  cell.    Cytoplasm-­‐  ___________________________  material  where    ___________________________  are  found.    Vacuole-­‐    __________________________filled  and  may  store    ______________________,                                    ___________________________,    _______________________  or  _______________________    Mitochondria-­‐  Produce  ____________________  when  food  is  broken                            down.    Known  as  the  ______________________________  of  the  cell.    Ribosomes-­‐  Where  _____________________  are  made.    There  may  be    ___________________  in  a  cell.    Centrioles-­‐  Found  only  in  ___________________________  cells  and  are                                                              used  in  cell  ________________________________.

                                             DNA  and  Cell  Division    

• During  cell  division,  genetic  material  is  __________________    

• DNA  is  divided  into  long  chains  called  ____________________    

• Chromosomes  are  wrapped  around  proteins  called  _______________    

• ___________________:the  unit  wrapped  around  histones.          Two  copies  of  each  chromosomes  are  called  sister  chromatids

 Chromosome  Structure    

• Normally  the  chromosomes  are  all  spread  out  and  unidentifiable.    This  is  called  __________________    

• The  two  chromosomes  are  called  sister  _____________________    

• The  chromatids  are  held  together  at  the  ____________________.                                                The  Cell  Cycle    

• The  length  of  time  a  cell  takes  in  the  cycle  depends  on  the  type  of  

cell.    Usually  the  more  specialized,  the  less  likely  they  are  to    

___________________  

 • Red  blood  cells  are  replicated  at  a  rate  of  _______million/sec  

 • Nerve  cells  do  not  usually  _________________________  and  remain  in  the  

G0  stage  until  they  ________________.

   Chromosome  number  is  maintained  because  the  DNA  is      _____________________  and  then  divides.    The  Spindle  Apparatus    

• Consists  of  ______  sets  of  microtubles    

• Move  the  _____________________  during  mitosis.      

• In  both  plants  and  animals  the  spindle  fibers  originate  from  

_____________________________.    In  animal  cells  the  centrosomes  are  

______________________________.  

   Mitosis  is  divided  into  _______  phases:    ___________________      ______________________    ________________________    ______________________    Describe  Interphase-­‐              Is  Interphase  part  of  mitosis?    Nuclear  envelope  visible-­‐YES  or  NO  Chromosomes  visible-­‐  YES  or  NO  Nucleolus  visible-­‐  YES  or  NO
