The Evolution of Prokaryotes: Archaebacteria and Eubacteria

1. The Evolution of Prokaryotes: Archaebacteria and Eubacteria

The first living organisms on Earth were bacteria. These small organisms still exist today and are responsible for many things. In this lesson, we will explore both ancient bacteria and true bacteria.

What is Bacteria? - Definition, Characteristics & Examples

2. 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

3. 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 Viruses? - Definition, Structure & Function

4. 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.

The Life Cycle of a Virus: How Viruses Live, Attack & Replicate

5. The Life Cycle of a Virus: How Viruses Live, Attack & Replicate

Find out how viruses infect and replicate as we explore the important steps of the virus life cycle, including attachment, uncoating, penetration, replication, and release, as well as the lysogenic and lytic cycles.

Archaebacteria: Definition & Examples

6. Archaebacteria: Definition & Examples

Archaebacteria survive and thrive in hostile environments, like hot springs and your intestines. This lesson will explore archaebacteria, describe how they are classified, and then give some examples of these extreme-loving organisms.

Lytic Cycle of a Virus: Definition & Steps

7. Lytic Cycle of a Virus: Definition & Steps

Viruses infect our cells, replicate, and then need to leave. One of the ways they choose to leave is by destroying the host cell. They do this by cutting (lysing) their way out. This is called the lytic cycle of a virus and is the subject of this lesson.
