Lesson Plan
Grade: Date: 17/01/2026
Subject: Biology
Lesson Topic: State that new cells are produced by division of existing cells.
Learning Objective/s:
  • State the principle that all new cells arise from pre‑existing cells.
  • Identify the two main types of cell division and the organisms in which they occur.
  • List and describe the sequential phases of mitosis.
  • Explain the roles of cell division in growth, repair, and asexual reproduction.
Materials Needed:
  • Projector or interactive whiteboard
  • PowerPoint/Google Slides presentation with diagrams
  • Printed worksheets with mitosis labeling activity
  • Microscopy images of dividing cells
  • Markers and chart paper for group mind map
  • Exit ticket cards
 Introduction:
Begin with a quick video showing a growing plant and a healing wound to hook interest. Ask students what they think enables these changes, linking to prior learning about cells as basic units. Clarify that today they will be able to state how new cells are produced by division of existing cells.
Lesson Structure:
  1. Do‑now (5'): Students answer a short question on the cell theory displayed on the board.
  2. Mini‑lecture (10'): Present the principle of cell continuity and introduce binary fission vs. mitosis with slides.
  3. Guided activity (15'): Groups label a mitosis diagram and arrange the phases in correct order.
  4. Whole‑class discussion (10'): Compare binary fission and mitosis, address common misconceptions.
  5. Formative check (5'): Exit ticket where each pupil writes the statement of cell division and one reason it is essential.
Conclusion:
Summarise that cell division is the only way new cells are made and review the mitotic phases. Students complete an exit ticket restating the key principle and one function of division. For homework, assign a short worksheet comparing binary fission and mitosis.
