Mitosis and Cell Division

Key Concepts

  1. Cell Division Cell division is the process by which a parent cell splits to form two new daughter cells. This process is essential for growth, repair, and reproduction in living organisms.
  1. Mitosis Mitosis is a type of cell division where one cell divides to produce two cells that are genetically identical to the original cell. It ensures that each new cell has the same number of chromosomes as the parent cell.
  1. Phases of Mitosis Mitosis occurs in several stages: prophase, metaphase, anaphase, and telophase. Each phase has specific events that help ensure accurate division of the cell’s genetic material.
  1. Importance of Mitosis in Growth and Repair Mitosis is important for the growth of an organism and for replacing damaged or dead cells. Without mitosis, living things would not be able to develop or heal properly.
  1. Chromosomes and Genetic Information Chromosomes carry genetic information in the form of DNA. During mitosis, chromosomes are duplicated and evenly distributed to each new cell, ensuring genetic consistency.

Standards Addressed

  • NGSS 3-LS1-1: Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.
  • NGSS 5-LS1-1: Support an argument that plants get the materials they need for growth chiefly from air and water.
  • CCSS.ELA-LITERACY.RI.5.3: Explain the relationships or interactions between two or more individuals, events, ideas, or concepts in a scientific text based on specific information in the text.

Assessment and Evaluation Plan

  • Formative Assessment:
  • Exit Ticket: At the end of the lesson, students will write one thing they learned about mitosis and one question they still have.
  • Think-Pair-Share: During the lesson, students will discuss with a partner what happens during each phase of mitosis.
  • Summative Assessment:
  • Diagram Labeling: Students will complete a worksheet where they label the phases of mitosis on a diagram and describe what happens in each phase.
  • Diagnostic Assessment:
  • K-W-L Chart: At the start of the lesson, students will fill out what they Know, what they Want to know, and later, what they Learned about cell division and mitosis.

Differentiation Strategy

  • For Struggling Learners:
  • Use visuals and hands-on activities, such as building mitosis models with clay or drawing diagrams.
  • Provide sentence starters and word banks for written assignments.
  • Offer additional support through small group discussions or one-on-one guidance.
  • For Advanced Learners:
  • Challenge students to compare mitosis with another type of cell division, such as meiosis, and present their findings to the class.
  • Encourage independent research on how errors in mitosis can lead to health problems.
  • Assign leadership roles in group activities to facilitate peer learning.
