Cell Structure and Function Cell/Developmental Biology I
Group Members • Kelly Hogan, Facilitator • Rita Graze • Matthew Kearley • Zheng-Hua Ye • Xiaoyu Zhang • Christine Sestero • Heather Tinsley
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 • 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) • 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) • 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?”
Summative AssessmentSample Exam Questions • Is the cell that is depicted below most likely taken from a plant or an animal? Provide 3 pieces of evidence to support your answer.
Summative AssessmentSample Exam Questions • For the cell structures indicated by the arrows, name the structure and list the primary function?
Summative AssessmentSample Exam Questions • Cell type A and cell type B contain the same types of organelles but have vastly different functions. Speculate how this is possible.
