April 12: Mitosis lab

 The mitosis slides are located in the second back room.  They can be a challenge to look at.  If they can be found then your teacher will assist you in observing these prepared slides .  


Draw mitosis under high power in the light  microscope in 3 pictures. Label the stages of mitosis

steps of cell cycle:  you should write a table showing the steps as well as the
FORM OF DNA
role of other organelles

1.  INTERPHASE -
a.  cell is undergoing growth.  After a period of growth, it prepares to divide
b.  cell replicates its DNA.  Nuclear membrane is still intact
2. PROPHASE
Nuclear membrane disappears and the chromosomes are visible
3.  METAPHASE
chromosomes line up in the middle and Centrioles send out the spindle fibres to attach to the centromere
4.  ANAPHASE
centromeres get ripped apart and thus the chromosomes get ripped apart into separate chromatids
5.  TELOPHASE
nuclear membrane reforms around the chromatids
6.  CYTOKINESIS
chromatin is in the nucleus now.
