Key Concepts

  • Cellular structure and function
  • Differences between plant and animal cells
  • Organelle functions and interactions

Learning Objectives

  • Students will be able to identify and describe the major organelles found in plant and animal cells.
  • Students will be able to compare and contrast the structure and function of plant and animal cells, highlighting key differences.
  • Students will be able to explain the roles of various organelles within the cell and how they contribute to the overall function of the cell.

Educator Instructions

  • Introduction (5 mins)
    Begin by engaging students with a captivating question: 'If you could shrink down and explore a cell, what would you hope to see?'. Briefly discuss the importance of understanding cell structure and function as the foundation of biology.
  • Video Viewing (15 mins)
    Play the Khan Academy video 'Overview of animal and plant cells | Biology | Khan Academy'. Instruct students to take notes on the key organelles and differences between plant and animal cells as they watch.
  • Guided Discussion (15 mins)
    Lead a class discussion based on the video, using the discussion questions provided below. Encourage students to share their notes and ask clarifying questions.
  • Interactive Exercise: Cell Diagram Labeling (15 mins)
    Students complete the interactive exercise (described below) to reinforce their understanding of cell structures.
  • Wrap-up and Assessment (10 mins)
    Summarize the key learning points of the lesson. Administer the multiple choice and fill-in-the-blank quizzes to assess student understanding.

Interactive Exercises

  • Cell Diagram Labeling
    Provide students with unlabeled diagrams of both plant and animal cells. Have them label the major organelles (nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes/vacuoles, chloroplasts, cell wall, cell membrane, cytoskeleton, peroxisomes) and briefly describe the function of each. This activity can be done individually or in small groups.

Discussion Questions

  • What are the key differences between plant and animal cells that you observed in the video?
  • How do the organelles within a cell work together to maintain its function?
  • Why is understanding the structure of a cell important in the study of biology?

Skills Developed

  • Observation and analysis
  • Critical thinking
  • Scientific communication
