Ch 12: Microbiology & Types of Microbes

About This Chapter

Watch video lessons about microbiology and the various kinds of microbes to learn more about life science. Each online lesson is accompanied by a self-assessment, which can help you make sure you've understood the material.

Microbiology and Types of Microbes - Chapter Summary and Learning Objectives

The study of microbiology and microbial life is a key part of life science; without it, there would be no vaccinations or antibiotics to fight illness. These video lessons, led by a qualified instructor, will provide you with an overview of this field, as well as key people who made significant contributions, such as Louis Pasteur and Edward Jenner. Learn about various kinds of microbes and their identifying qualities and characteristics, from archaea to bacteria to algae and fungi. At the end of this chapter, you should be able to:

  • Explain two key theories of germs and disease
  • Identify Louis Pasteur's role in the early days of microbiology
  • Discuss Edward Jenner and his work in the development of vaccines
  • Describe how antibiotics were developed and how they work
  • Identify and describe several types of microbes, outlining similarities and differences among them.

Video Objective
The Germ Theory of Disease: Definition & Louis Pasteur Discuss the theory of spontaneous generation and the germ theory of disease; describe the role of Louis Pasteur in these theories.
Antibiotics and Vaccines Discuss Edward Jenner and the first vaccines; outline the concept of sanitation and the development of antibiotics and how they work.
Eukaryotic and Prokaryotic Cells: Similarities and Differences Compare and contrast the structure and function of these two types of cells.
Archaea: Definition, Characteristics & Examples Identify examples of archea, and describe what makes it different from other kinds of microbes.
What is Bacteria? - Definition, Characteristics & Examples Discuss what eubacteria are; compare and contrast them to other kinds of microbes.
Cyanobacteria: Definition, Characteristics & Species Explain what cyanobacteria are and how they are different from other types of microbial life.
What are Protozoa? - Definition, Characteristics & Examples Outline the defining qualities of protozoa; compare and contrast them with other kinds of microbes.
What is Algae? - Definition, Characteristics & Examples Describe identifying characteristics of algae, and discuss how it varies from other types of microbes.
What are Fungi? - Types and Characteristics Discuss what fungi are; compare and contrast them to other kinds of microbial life.

The Germ Theory of Disease: Definition & Louis Pasteur

1. The Germ Theory of Disease: Definition & Louis Pasteur

In this lesson, we will look at one of the most influential experiments in the field of microbiology. We will learn how Louis Pasteur disproved the theory of spontaneous generation which helped lead to the development of the germ theory of disease.

Antibiotics and Vaccines

2. Antibiotics and Vaccines

Do you know why children must get regularly vaccinated? Have you ever wondered how an antibiotic works and why they are so widely prescribed? If so, this lesson will help you to understand how changes in medicine have almost eliminated several deadly diseases and added decades to the average person's lifespan.

Archaea: Definition, Characteristics & Examples

3. Archaea: Definition, Characteristics & Examples

There is an entire domain of life that is made up of single-celled organisms without nuclei. We're not referring to the Bacteria domain, however. In this lesson, we will examine the main characteristics of the least commonly known domain, the Archaea.

What is Bacteria? - Definition, Characteristics & Examples

4. What is Bacteria? - Definition, Characteristics & Examples

This lesson will introduce the Bacteria, a large and diverse group of microorganisms. We will examine several key characteristics, as well as a few commonly known examples of bacterial species.

Cyanobacteria: Definition, Characteristics & Species

5. Cyanobacteria: Definition, Characteristics & Species

Cyanobacteria are a phylum of Bacteria that produce oxygen during photosynthesis. This lesson will examine cyanobacteria and the role they played in establishing our oxygen-rich atmosphere.

What are Protozoa? - Definition, Characteristics & Examples

6. What are Protozoa? - Definition, Characteristics & Examples

Taxonomy is the realm of science that attempts to group similar organisms together, which is not always an easy task. In this lesson, we will examine the protozoa, a diverse group of organisms that didn't really fit anywhere else.

What is Algae? - Definition, Characteristics & Examples

7. What is Algae? - Definition, Characteristics & Examples

Plants are not the only organisms capable of carrying out photosynthesis. In this lesson we will look at algae and how an algal species can be differentiated from other organisms and microbes.

What are Fungi? - Types and Characteristics

8. What are Fungi? - Types and Characteristics

In this lesson, we will examine the group of organisms known as the fungi. This group includes the familiar organisms mushrooms, yeasts and molds. We will look at several major characteristics of fungi, as well as a few disease-causing fungi.
