Cell Biology Mitosis Worksheet

Mitosis Worksheet Study Notes

• Matching:

  • Interphase (I): Chromatin is in nucleus, no visible chromosomes.
  • Prophase (P): Nuclear membrane disappears, chromosomes condense.
  • Metaphase (M): Chromosomes line up at cell's equator.
  • Anaphase (A): Sister chromatids separate and move to opposite poles.
  • Telophase (T): New nuclear membranes form around separated chromosomes, spindles disappear.

• Fill in the Blanks:

  • Cytokinesis (2x): Phase where the cytoplasm divides, forming two daughter cells.
  • Sister Chromatid: Each half of a duplicated chromosome.
  • Anaphase: Chromosomes separate, move away from the middle.
  • Centromere: Structure holding the two sister chromatids together.
  • Telophase: Reverse of prophase; nuclear membranes reappear.
  • Metaphase: Sister chromatids line up in the middle of the cell.
  • Cell Plate: Structure forming in plant cells during cytokinesis, forming new cell walls.

• Additional Information:

  • Mitosis: Cell division that creates two genetically identical diploid daughter cells from a single parent cell. Crucial for growth and repair in multicellular organisms.
  • Interphase: The stage of the cell cycle where the cell grows, replicates DNA, and prepares for division.
  • Phases of the Cell Cycle:
  • Interphase: G1 (cell growth), S (DNA replication), G2 (preparation for mitosis).
    • Mitosis: includes prophase, metaphase, anaphase and telophase.
    • Cytokinesis: Division of the cytoplasm and cell organelles.
  • Structures in the Diagrams:
    • Be ready to identify structure X in the diagrams.

Further Study Points:

• Diagram Analysis: Recognize the stages of mitosis in the accompanying diagrams.
• Cell Type Differentiation: Distinguish between plant and animal cell cytokinesis.
• Emphasize the importance of mitosis in various biological processes.
• Identify the key structures (X) in the diagrams and their functions.
• Analyze diagram components to determine cell phases.
• List the processes in the correct sequence, from beginning to end.

This quiz covers the stages of mitosis, including key processes and terminology. Test your understanding of interphase, prophase, metaphase, anaphase, and telophase with matching and fill-in-the-blank questions. Perfect for students studying cell division in biology.
