You will get to see the definition, types and uses of microbes along with other lesson information that includes:
- Shapes, arrangements and the definition of bacterial cell morphology
- The definition of a virus, its structure and its function
- Characteristics and examples of protozoa cells, and its definition
- Definition, characteristics and examples of algae
- Types of fungi and the characteristics of each
- Normal human flora and its role in the prevention of disease
Video lessons are hosted by our instructors, each lasting five to ten minutes in run time, and they make use of a video timeline tool that you can use to quickly go to any portion of the video you want to replay. All lessons have an accompanying short assessment quiz to check your understanding of the material covered.
1. What is Microbiology? - Definition & History
Everywhere you look, even though you can't see them, there is a hidden world of microorganisms. Microbiology is the study of this hidden world of organisms that affect our health, help make our food, and influence our environment.
2. What Are Microbes? - Definition, Types & Uses
Microbes are the tiny microorganisms that inhabit the world with us, around us, and even in us. Learn more about how these microscopic beings affect our lives.
3. 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.
4. 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!
5. 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.
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.
7. 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.
8. Preventing Disease: Normal Human Flora
This lesson will give you a basic understanding of what human flora is. You'll learn about the different locations of flora, such as the gut, and what mutualistic, commensal, and opportunistic microbes are.
