Learning Goal:

Understand how organelles/cell structure relate to the overall function of the cell.

  • How is cell structure and content responsible for differences between plant and animal cells or cell types in different tissues?
  • What functions are not related to the organelles/cell structure?

Learning Objectives:

  • Identify the major cell organelles.
  • List the major functions of the organelles.
  • Predict how changes in organelle/cell structure could alter cellular function .
  • Explain how overall cellular function is dependent upon organelles/cell structure.
  • Relate cell structure to every day contexts.

Target Audience: Introductory biology course for non-majors;

One 50 minute lecture.

unit outline
Unit Outline
  • Pre-class: Students read the chapter about cells and organelles in their textbook. 1 hour
  • Introduction: Review with students what activities cells must perform and which organelles are responsible for these activities. 10 minutes
  • Activity #1: Students build a model plant or animal cell. 10 minutes
  • Activity #2, Cell Detective: Students build an imaginary cell suited for a specific function; students exchange cells and attempt to guess function. 15 minutes
  • Mini-lecture: Give real life examples of how cell structure aids with function; clarify misconceptions revealed during activities. 10 minutes
  • Summation: Leave students with a thought-provoking question to take their understanding a step further. 5 minutes

Cell Detective
  • Part 1: Design a cell.
  • Part 2: Exchange with a neighbor and guess the identity of your neighbor’s cell.
  • Part 3: Discuss with the class.

Cell Detective (Part 1 – 7 minutes)
  • Each group has a handout with a specific description of an imaginary cell.
  • Your task is to draw a cell that best fits the description given.
  • Be sure to pay particular attention to any differences that this cell should possess when compared to the model cell that you constructed earlier.
  • Begin by deciding on and drawing the outline of the cell, then fill in with the appropriate organelles.
  • Be sure to label the organelles, but do not write the function of your cell on the paper.
  • Feel free to use your notes and textbook.
cell detective part 2 5 minutes
Cell Detective (Part 2 – 5 minutes)
  • Exchange your cell with a neighboring group.
  • DO NOT GIVE YOUR DESCRIPTION TO THE OTHER GROUP.
  • As a group, try to decide what the function of your neighbor’s cell is.
  • Again, pay particular attention to how the cell in front of you differs from the model cell with which you are familiar.
cell detective part 3 3 minutes
Cell Detective (Part 3 – 3 minutes)
  • Share with the class what you think the function of your neighbor’s cell is and why.

Post-Activity Summing Up/Transition (5 min.)
  • Have students ponder the question:

“Do differences in organelles alone account for the different functions of cells?”

  • Cell type A and cell type B contain the same types of organelles but have vastly different functions. Speculate how this is possible.
