| Lesson Topic: explain the importance of mitosis in the production of genetically identical daughter cells during: growth of multicellular organisms, replacement of damaged or dead cells, repair of tissues by cell replacement, asexual reproduction |
Learning Objective/s:
- Describe the phases of mitosis and cytokinesis and the key events in each phase.
- Explain why genetic identity of daughter cells is essential for tissue function and organismal development.
- Analyse how mitosis contributes to growth, cell replacement, tissue repair, and asexual reproduction with specific examples.
- Evaluate the consequences of errors in mitotic division for organism health.
- Apply knowledge of mitosis to interpret diagrams and predict outcomes of cell‑cycle disruptions.
|
Materials Needed:
- Projector and screen
- PowerPoint slides with mitosis diagrams
- Printed handouts of the mitotic cycle
- Microscope slides of onion root tip (for observing mitosis)
- Worksheet for case‑study activity
- Whiteboard and markers
- Kahoot/Quizizz access for exit quiz
|
Introduction:
Begin with a short time‑lapse video of a wound healing, asking students how new cells appear. Prompt them to recall the stages of the cell cycle and DNA replication covered previously. Explain that today they will explore how mitosis creates genetically identical cells to support growth, repair, and asexual reproduction, and they will be able to diagram each phase and justify its role.

Lesson Structure:
- Do‑now (5') – Students label a blank mitosis diagram from memory (retrieval practice).
- Mini‑lecture (10') – Overview of the cell cycle and detailed description of the six mitotic phases with slide images.
- Interactive simulation (10') – Online animation where students identify phase transitions and answer click‑questions.
- Group activity (15') – Each group receives a case study (growth, replacement, repair, asexual reproduction) and creates a poster linking mitosis to the scenario.
- Guided practice (10') – Worksheet matching tissue‑function descriptions to the need for genetic identity.
- Formative check (5') – Quick exit quiz (Kahoot) on key concepts.
- Summary discussion (5') – Teacher highlights common misconceptions and clarifies understanding.
|
Conclusion:
Summarise that mitosis ensures identical genetic material for new cells, enabling organisms to grow, replace lost cells, repair tissue, and reproduce asexually. Collect an exit‑ticket where each student writes one real‑world example of mitosis in action. Assign homework to read a short article on uncontrolled mitosis in cancer and write a one‑paragraph reflection.
