What Do You Need Today? Mitosis Stages Drawing Sheet
Regular Pen or Pencil Brown Colored Pencil Blue Colored Pencil Red Colored Pencil Purple Colored Pencil
3
Nuclear envelope and nucleolus are present
INTERPHASE G1: Cells Grow and Develop Nuclear envelope and nucleolus are present Chromatin is present
4
INTERPHASE S (SYNTHESIS): Chromosomes condense and replicate
Nuclear envelope and nucleolus are present Replication Homologous pairs are present Sister Chromatids
5
INTERPHASE G2: Cell makes organelles and gets larger
Nuclear envelope and nucleolus are present Centromere = holds the sister chromatids together
6
PROPHASE Centrioles (2) form & start to move to the poles
Nuclear envelope and nucleolus disappear Spindle starts to form & will attach to chromosomes
7
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
8
ANAPHASE Spindle fibers pull sister chromatids to opposite sides of the cell Centromeres divide Independent Daughter Chromosomes
9
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
10
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
