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

Louis Pasteur's Germ Theory of Disease asserts that microorganisms contribute to human illness. Learn how bacteria colonize on surfaces, how Pasteur's Germ Theory of Disease actually refutes spontaneous generation, and how microbiology affects food safety.

Antibiotics and Vaccines

2. Antibiotics and Vaccines

Antibiotics and vaccines have a great contribution to the increase in life expectancy over time. Learn more about the history of antibiotics and vaccines, and how different types of vaccines are developed.

Archaea: Definition, Characteristics & Examples

3. Archaea: Definition, Characteristics & Examples

Archaea are single-celled organisms distinct from Bacteria or Eukarya. Explore what makes these unique, learning about Extreme Halophiles, Thermoacidophiles, and characteristics of their metabolism which enable their survival in harsh environments.

What is Bacteria? - Definition, Characteristics & Examples

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

Despite being small, bacteria has a serious effect. Learn defining characteristics and examples of bacteria, how it grows and metabolizes, and its role in health and disease.

Cyanobacteria: Definition, Characteristics & Species

5. Cyanobacteria: Definition, Characteristics & Species

Cyanobacteria are oxygenic phototrophs, which means they can generate oxygen and release it while using light photons. Explore the definition, characteristics, and species of cyanobacteria, the oxygen atmosphere, and learn about the morphology, roles, common genera, and contributions to life made by cyanobacteria.

What are Protozoa? - Definition, Characteristics & Examples

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

As diverse microorganisms within a group, protozoa are organized into four different groups by their movement. Learn more about the definition of protozoa, including early problems with its classification, characteristics, and explore the four groups of protozoa through examples.

What is Algae? - Definition, Characteristics & Examples

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

Unlike plants, the eukaryotic microorganism Algae can't specialize tissue into features like flowers or roots. Discover the features of algae and its diverse types through examples from around the world.

What are Fungi? - Types and Characteristics

8. What are Fungi? - Types and Characteristics

Mushrooms, molds, and yeasts are examples of fungi, a group of eukaryotic, non-phototrophic organisms with rigid cells. Learn about the age of fungi, their different types, and their characteristics.
