Mitosis and Its Phases Quiz

Aim and Do Now

• Aim: How can we describe mitosis and its phases?
• Do Now: If a cell is growing, why does it need to divide?

Mitosis

• Mitosis is the process where a cell separates its chromosomes into two identical sets in two nuclei.
• DNA replication precedes mitosis.
• Mitosis results in two diploid cells.
• The parent cell is identical to the two daughter cells.
• The number of chromosomes remains the same (e.g., 46 chromosomes in a human cell remain 46).
• It produces all cell types except sex cells

Phases of Mitosis

• Interphase:
  • Chromosomes replicate.
• Prophase:
  • Spindle fibers radiate from opposite poles.
  • Nuclear membrane disappears.
• Metaphase:
  • Chromatids move to the central plate (middle).
  • Chromatids align in the center.
• Anaphase:
  • Chromatids separate and are pulled apart.
  • Chromatids move toward the poles.
• Telophase:
  • Nuclear membrane reappears, forming two nuclei.
  • Cytoplasm splits (cytokinesis).
  • The pinching in is known as the cleavage furrow

Plant vs Animal Cells

• Centrioles: Only in animal cells, they help form spindle fibers.
• Cell Plate: In plant cells, it forms during telophase, which helps divide the cell.
