Ch 8: Understanding Cell Transportation

About This Chapter

Get an understanding of cell transportation, including topics such as diffusion and osmosis with the brief lessons and quizzes in this chapter. These interesting study aids are a great resource for supplementing class materials or preparing for a test.

Understanding Cell Transportation - Chapter Summary

In these lessons, you'll gain an understanding of cell transportation. Topics covered include both active and passive transport in cells, capillary fluid exchange and the exchange of materials in the body. After completing the chapter, you should be able to do the following:

  • Define diffusion and osmosis
  • Identify factors that affect diffusion and osmosis
  • Describe the respiratory surface and gas exchange efficiency
  • Understand capillary fluid exchange
  • Recognize active transport in cells
  • Explain passive transport in cells, including simple and facilitated diffusion and osmosis
  • Discuss exchanging materials using specialized cells, tissues, and organs

Our subject matter experts present the information in these short videos in an engaging manner, including plenty of examples to ensure the material is easy to understand. The video timeline can be used to go directly to the topics of greatest interest. A brief multiple-choice quiz is available for each lesson to test your knowledge. You can also print the lesson quizzes and use them as worksheets.

What is Diffusion?

1. What is Diffusion?

Learn about diffusion and how this process works. We'll look at some examples of diffusion happening. You'll be able to take the short quiz that follows to test your knowledge.

Osmosis: Definition & Examples

2. Osmosis: Definition & Examples

Water moves across cell membranes by osmosis to try to equalize the concentration of solutes on both sides of the membrane. In this lesson, learn how osmosis works and examine some examples of its importance in biology.

The Respiratory Surface and Gas Exchange Efficiency

3. The Respiratory Surface and Gas Exchange Efficiency

The respiratory membrane includes millions of alveoli with a surface area as large as a tennis court. This large respiratory surface area, combined with other factors, makes for efficient gas exchange to meet our metabolic needs.

Capillary Fluid Exchange

4. Capillary Fluid Exchange

How do we get nutrients from blood into the rest of our bodies? The answer is through capillary fluid exchange, and in this lesson we'll discuss what this process is and how it works. Then, test your understanding with a brief quiz.

Active Transport in Cells: Definition & Examples

5. Active Transport in Cells: Definition & Examples

In this lesson, we'll learn how substances are transported across the cell membrane against the concentration gradient. This might seem like an uphill battle for the cell, but all it takes is a little chemical energy and a few integral membrane proteins to kick off some active transport!

Passive Transport in Cells: Simple and Facilitated Diffusion & Osmosis

6. Passive Transport in Cells: Simple and Facilitated Diffusion & Osmosis

A cell membrane is selectively permeable - not permeable to everything. In this lesson, we'll talk about methods of passive transport along a concentration gradient, including simple and facilitated diffusion and osmosis.

Exchanging Materials: Specialized Cells, Tissues & Organs

7. Exchanging Materials: Specialized Cells, Tissues & Organs

In this lesson we'll be looking at ways that plants and animals transport materials through their surfaces. We'll look at general characteristics of these types of tissues as well as specific examples such as the small intestine, lungs, gills, roots and leaves.
