Ch 7: The Cell Membrane

About This Chapter

This collection of biology lessons covers important topics related to the cell membrane. Work through the chapter at your own pace to study for exams, boost your grades or improve your overall understanding of cell membrane terms and processes.

The Cell Membrane - Chapter Summary

This biology study resource provides a thorough look into the cell membrane. As you work through the chapter, you'll examine the structure of a cell's plasma membrane as well as the purpose of endocytosis and exocytosis. Our expert biology instructors also help you define terminology related to active and passive transport in cells. After completing the chapter's lessons, you should be able to:

  • Explain the function of a cell's plasma membrane
  • Outline several active and passive transport methods in cells
  • Evaluate the purposes of the endocytosis and exocytosis processes

The chapter comes with several interactive tools to enhance your studying experience. Each video lesson has an interactive timeline that allows you to jump to specific points in the lesson. Self-assessment quizzes are also included to help you check your understanding of the material. You can ask our expert instructors questions if they come up using your personal Dashboard. For offline study, print word-for-word lesson transcripts. The lessons are also available to access on any computer, smartphone or tablet.

Plasma Membrane of a Cell: Definition, Function & Structure

1. Plasma Membrane of a Cell: Definition, Function & Structure

Cells are made of many crucial parts that work together and perform specific functions. In this lesson, you will learn about the plasma membrane of a cell to gain an understanding of its structure and function.

Passive Transport in Cells: Simple and Facilitated Diffusion & Osmosis

2. 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.

Active Transport in Cells: Definition & Examples

3. 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!

Endocytosis: Definition, Types & Examples

4. Endocytosis: Definition, Types & Examples

Discover how cells 'eat' and 'drink' without having hands or a mouth! Read about the various ways in which cells accomplish this, and take a quiz to test your understanding.

Exocytosis: Definition & Examples

5. Exocytosis: Definition & Examples

Like a factory, cells make products. Some of these stay in the cell and others are exported. This lesson is about how cellular products are shipped out of the cell using a process called exocytosis.
