Life Stages: Mitosis
Life Stages: Mitosis
Objectives
In this lesson, students will learn about the phases of mitosis by predicting the order of the phases and by drawing diagrams of the chromosomes during the various phases. Students will:
- make connections between cell division and the growth of organisms.
- predict the order of the phases of mitosis given diagrams in a scrambled order.
- diagram the various stages of mitosis showing the movement of chromosomes in the cell.
- create mnemonic devices to help students remember the order of the phases.
Essential Questions
Vocabulary
- Mitosis: The process by which a cell separates the two copies of its DNA into two daughter cells.
- Interphase: The phase of the cell cycle in which chromosomes are not visible (unwound as chromatin, not condensed as chromosomes).
- Prophase: The phase of the cell cycle in which chromosomes are visible.
- Metaphase: The phase of the cell cycle in which chromosomes are lined up in the cell.
- Anaphase: The phase of the cell cycle in which the chromosomes are separated/ separating.
- Telophase: The phase of the cell cycle in which the nucleus reforms after anaphase.
- Cytokinesis: The phase of the cell cycle in which the cell membrane is fully separated between daughter cells.
- Chromosome: A condensed structure in the cells of all organisms that is made up of DNA.
- Haploid: A cell that contains one set of chromosomes (and only a single set of genes).
- Diploid: A cell that contains both sets of homologous chromosomes.
- Somatic: A body cell.
- Sex cell: An egg or sperm; sex cells are haploid.
- Zygote: A fertilized egg.

Prerequisite Skills
Prerequisite Skills haven't been entered into the lesson plan.
Materials
- colored pencils/markers (red, orange, light blue, dark blue) for each pair of students. Any colors work but it will be best for meiosis later if they use a pair of similar colors and another pair of similar colors (for example dark and light green, and dark and light brown)
- Drawing Mitosis PowerPoint presentation (S-7-4-2_Drawing Mitosis Presentation.pptx)
- Mitosis Phases Sorting (S-7-4-2_Mitosis Phases Sorting.docx), one set per group
- Mitosis and Meiosis Drawing Packet (S-7-4-2_Mitosis and Meiosis Drawing Packet and KEY.docx)
