Chromosomes
Diploid: contains 2 sets of chromosomesBody cells, 2n
Haploid: contains 1 set of chromosomesGametes, sex cells, n
Sister chromatids- 2 identical chromatids held together by a centromere
Kinetochores: protein complex that develops on either side of centromere.
Phases of Mitosis
Prophase Centrosomes have duplicated Chromatin condenses into chromosomes Spindles forming Nucleolus and nuclear envelope disappear
Metaphase Centromeres/chromosomes aligned along middle Spindles attach to kinetochore
Anaphase Sister chromatids are pulled apart and daughter chromosomes move toward
opposite poles. Cleavage furrow begins to form
Telophase Nuclear envelope and nucleolus reappear. Chromosomes begin to uncoil
cytokinesis
Division of the cytoplasmAnimal cell
Cleavage furrow formsBand of actin filaments (contractile ring), forms a
circular constrictionPlant cell
Golgi apparatus forms vesicles which move along the microtubules to the region of a small disk seen between the 3 daughter plant cells
Cell plate (newly formed plasma membrane) forms between the daughter cells
