Ch 8: Understanding Microbiology

About This Chapter

This chapter on microbiology offers a quick and effective method for studying foundational microbiology topics. Use the chapter to prepare for exams, refresh your knowledge and practice answering microbiology questions.

Understanding Microbiology - Chapter Summary

Study this collection of science study resources to learn/review essential microbiology terms and concepts. Our expert instructors break down microbiology processes in a direct and simple manner, which allows you to quickly understand concepts such as bacterial cell morphology, binary fission, bacterial transduction and more. You'll also learn about the purpose of bacteriophages and outline their lytic and lysogenic cycles. Finally, you'll examine concepts related to virus structures and classifications.

After completing each lesson in the chapter, you'll be equipped to:

  • Recognize various classifications, shapes and arrangements in bacterial cell morphology
  • Identify several bacterial structures and explain their functionalities
  • Understand how binary fission reproduces bacteria
  • Define the process of bacterial conjugation, transformation and transduction
  • Know what viruses are, what they do, how they're structured and how they're classified
  • Explain how a bacteriophage attacks bacteria
  • Outline the process of the bacteriophage's lytic and lysogenic cycles

Each lesson is crafted to be engaging, informative and concise. That way, you can be sure you're learning the most important microbiology information as quickly and efficiently as possible. Each lesson comes with a short self-assessment quiz to help you solidify your understanding of key terms and concepts. You can also supplement your studying experience by printing the included lesson transcripts and asking our instructors questions as they arise. These lessons are also available at any time of day or night, and you can use any computer or mobile device to access them.

Bacterial Cell Morphology and Classification: Definition, Shapes & Arrangements

1. Bacterial Cell Morphology and Classification: Definition, Shapes & Arrangements

Do all bacteria look the same? Definitely not! These tiny, singled-celled organisms come in a variety of morphologies, from cocci to spirals to tetrads. Many bacterial names even have clues to their morphology!

Bacterial Structures and Their Functions

2. Bacterial Structures and Their Functions

A bacterial cell is not smooth like a balloon. Bacteria can be covered with a wide range of structures like pili and capsules that give each species of bacteria different abilities. In this lesson, you will learn about several of these key external structures of bacteria.

Binary Fission: Definition, Steps & Examples

3. Binary Fission: Definition, Steps & Examples

Bacteria are all around you, some make you sick, some are helpful. This lesson will examine one way bacteria reproduce called binary fission. It will also give you some examples of bacteria you may encounter.

Bacterial Conjugation: Definition & Protocol

4. Bacterial Conjugation: Definition & Protocol

You probably didn't know that bacteria can engage in sexual reproduction. It is not what you think. In this lesson we will explore the process of bacterial conjugation and its impact on genetic variability in bacteria.

Bacterial Transformation: Definition, Process & Applications

5. Bacterial Transformation: Definition, Process & Applications

DNA is all around you. So are bacteria. Did you know that those bacteria can pick up and use that DNA? In this lesson we will examine the process of transformation and how bacteria are able to make use of environmental DNA.

Bacterial Transduction: Definition, Process & Advantages

6. Bacterial Transduction: Definition, Process & Advantages

Genetic diversity allows organisms to adapt to changing environmental conditions. In this lesson, we will explore bacterial transduction and how it allows bacteria to transfer genes and increase genetic diversity.

What Are Viruses? - Definition, Structure & Function

7. What Are Viruses? - Definition, Structure & Function

In this lesson, you'll learn some historical facts about viruses and the material they are composed of. Find out more as we review the capsid, nucleic acids, the viral envelope, viruses, virions, bacteriophages and virology.

Classification of Viruses: Viral Genome and Replication Scheme

8. Classification of Viruses: Viral Genome and Replication Scheme

Find out how viruses are classified based on their being double-stranded, single-stranded, positive-sense, negative-sense, or by having something called reverse transcriptase.

Bacteriophage: Definition & Types

9. Bacteriophage: Definition & Types

A bacteriophage is a virus that exclusively attacks bacteria. Its sole purpose is to use the bacteria for reproduction. In this lesson, learn more about this microscopic invader and take a short quiz at the end.

Viruses: Bacteriophage Lytic and Lysogenic Cycles

10. Viruses: Bacteriophage Lytic and Lysogenic Cycles

Viruses are generally not only our enemy but also the enemy of many other organisms. Bacteriophages are viruses that infect specific bacteria. In this lesson, we'll discuss their basic structure and infection cycle.
