Diffusion, Osmosis & Active Transport Lecture
These
are the Diffusion, Osmosis & Active Transport Lecture materials of the Virtual Cell
Biology Classroom. The resources below are used to supplement an actual
college cell biology course. Anyone taking, teaching or interested in
biology may find these resources helpful and is welcome to use them.
The Diffusion, Osmosis & Active Transport Lecture materials include:
- a list of learning objectives
- a PowerPoint lecture
- a homework assignment
- "class note" articles
- practice test questions
- review questions
- links to additional educational resources
DIFFUSION, OSMOSIS & ACTIVE TRANSPORT LEARNING OBJECTIVES
- Diffusion, osmosis, and active transport; Understand how these processes relate to molecules moving across the plasma membrane.
- What is the plasma membrane, its role and what it is made of?
- What is tonicity (isotonic, hypertonic, hypotonic), and how does it relate to osmosis.
- What is a concentration gradient?
- Be able to solve tonicity problems (What would happen to a cell sitting in various concentrations of solution. Be able to tell me which way water would move, into or out of the cell.)
- What is active transport? How does it differ from diffusion and active transport?
DIFFUSION, OSMOSIS & ACTIVE TRANSPORT LECTURE POWERPOINT
All of the lecture PowerPoints used in the Virtual Cell Biology Classroom have fill-in-the-blanks on many of the slides to encourage students to pay attention and follow along during the presentation. Instructors can contact us for the information that goes in the blanks.
HELPFUL TIPS: Some of the PowerPoint presentations are large files and may take a few moments to download, depending on the speed of your internet connection. If you are printing a hard copy of the PowerPoint, you can save paper by selecting Handouts (rather than Slides) in the "Print What:" drop down menu of the PPT print screen. Then you can choose the number of slides you want to have on each printed page. If the printed PPT presentation is to be used as student notes, it is best to choose handouts with 2 or 3 slides per page.
DIFFUSION, OSMOSIS & ACTIVE TRANSPORT HOMEWORK
Word document of a single essay question given to students at the end of the lecture. This tool helps the students review the main messages of the lecture while allowing the instructor to assess the class' understanding of the material.
DIFFUSION, OSMOSIS & ACTIVE TRANSPORT CLASS NOTES
Here are brief summaries of some of the various subtopics and concepts introduced in this lecture, kind of like really good class notes.
DIFFUSION, OSMOSIS & ACTIVE TRANSPORT PRACTICE TEST QUESTIONS
This link takes you to practice test questions designed to help you better understand the material from this lecture. They are based on information in the Diffusion, Osmosis & Active Transport PowerPoint Lecture.
DIFFUSION, OSMOSIS & ACTIVE TRANSPORT REVIEW QUESTIONS
This link takes you to review questions dedigned to help you review the material in the Diffusion, Osmosis & Active Transport PowerPoint Lecture.
