Nuclear envelope and nucleolus are present INTERPHASE G1: Cells Grow and Develop Nuclear envelope and nucleolus are present Chromatin is present

INTERPHASE S (SYNTHESIS): Chromosomes condense and replicate Nuclear envelope and nucleolus are present Replication Homologous pairs are present Sister Chromatids

INTERPHASE G2: Cell makes organelles and gets larger Nuclear envelope and nucleolus are present Centromere = holds the sister chromatids together

PROPHASE Centrioles (2) form & start to move to the poles Nuclear envelope and nucleolus disappear Spindle starts to form & will attach to chromosomes

METAPHASE Chromosomes line up in the middle on Metaphase Plate Spindle fibers attach to centromere of each sister chromatid Metaphase Plate: imaginary line down center of cell

ANAPHASE Spindle fibers pull sister chromatids to opposite sides of the cell Centromeres divide Independent Daughter Chromosomes

TELOPHASE 2 nuclei reappear around each set of chromosomes Chromosomes start to uncoil back into chromatin Spindle fibers dissolve Centrioles start to disappear Each daughter cell has exact amount of chromosomes as the parent

CYTOKINESIS: Cytoplasm Division Cell membrane pinches in forming a CLEAVAGE FURROW 1. Membrane fragments gather in center forming CELL PLATE (becomes the cell membrane) 2. Cell wall forms between the membranes ANIMAL CELLS PLANT CELLS
