Chapter 3. Chapter 3: Cell Structure and Function

Introduction

1. What structural features are shared by all cells, and what are the key differences between prokaryotic and eukaryotic cells?

2. How do solutes and water cross membranes, and what determines the direction of movement of solutes and water in different situations?

3. How do antibiotics target bacteria, and in what situations is antibiotic therapy indicated?

4. What are some key eukaryotic organelles and their functions?

The presentation is organized around the driving questions, with opportunities for active and collaborative learning built into each driving question (e.g. brainstorming, clicker questions and mini-cases). Students have the opportunity to consider their understanding of each driving question before you move on to the next. The presentation wraps up with an activity for students to understand why there are limited treatment options for viral and fungal infections, relative to bacterial infections.

1. Assign the first section of the chapter as a reading (up to the heading “Bug Bullet”)

2. Assign Animation 3.3 (LaunchPad). This is an interactive activity to introduce and compare and contrast prokaryotic and eukaryotic cells.

2. Assign Animation 3.8 (LaunchPad). This is an interactive activity to learn about the major organelles in eukaryotic cells.

Use (or modify) the lecture slides (available for download below). The lectures slides start with a review of the prep assignment (collaborative discussion and clicker questions), then move through each Driving Question. The slides include additional information and notes in the “Notes” section under each slide (visible in “Normal” or “Notes Page” view).

1. Assign the entire chapter as an after-class reading

2. Select additional practice questions (e.g. from the end of chapter or LaunchPad resources) for students to complete

3. (Optional) Have students find news reports about an outbreak. Have them investigate the outbreak, emphasizing the cause (what is the structure of the pathogen?), and what treatment or prevention options exist. Have them discuss during the next class meeting.
