Cells

Interphase

Cell Cycle

  • G1 Phase
    • The cell grows and doubles in size, reproducing its organelles.
    • What doubles in the ^1670442523570 g1 phase? ;; ^1670442541145Enzymes, Cytoplasmic organelle.
  • S Phase
    • Doubles the amount of DNA, doubles the amount of chromosomes.
  • G2 Phase
    • The mitochondria divides and chloroplasts divides as well, if it is a plant cell.

Mitosis

Cell Cycle

  • Prophase - 2 copies of each chromatid, attached with a centromere. Formation of mitotic spindles + microtubules and the nucleus starts to dissipate.
  • Prometaphase | Late prophase
    • Nuclear membrane fragments and microtubules are in the nuclear area.
    • The spindle is formed.
      • It will seperate the chromosomes into Chromatids.
    • Attaches to Chromatids
    • Centrioles move
  • Metaphase
    • The chromosomes move towards the middle of the cell.
    • Spindles attach to centromeres and sister chromatids.
    • Centrioles connect the mitotic spindles to the edge of each cell.
  • Anaphase
    • Centromeres divide.
    • The chromosomes split[1] and are brought to opposite sides of the cell to prepare for the whole cell to envelope in and split.
  • Telophase
    • The nucleus on each side starts to bring in the daughter chromosomes and start to reform their nuclear membranes. Chromosomes split back into chromatins.
    • Where the two cell membranes start to form, it is called ;; Cleavage furrow

Cytokinesis

Cell Cycle

  • Organelle split and goes into the new cell.
  • In a {1:plant cell} a cell wall or {2:cell plate} generates to split the two.
