  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Bacteria and Viruses chapter exam.

Why It Works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the Bacteria and Viruses chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any question about bacteria and viruses. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students Will Review:

This chapter helps students review the concepts in a bacteria and viruses unit of a standard cell biology course. Topics covered include:

  • Bacterial cell morphology and classification
  • Structure of bacterial cells
  • Viruses
  • Bacteriophage lytic and lysogenic cycles

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 Cell Walls: Structure, Function & Types

2. Bacterial Cell Walls: Structure, Function & Types

The bacterial cell wall has to be strong to prevent cell lysis but also porous to allow transport across the cell membrane. In this lesson, we will examine the structure of the bacterial cell wall and how it accomplishes both of these crucial tasks.

Bacterial Cytoplasm & Cell Membrane: Structure & Components

3. Bacterial Cytoplasm & Cell Membrane: Structure & Components

Some people say a bacterial cell is just a simple bag of enzymes. This couldn't be further from the truth! Learn about the structure and function of the bacterial cell membrane, what's in the cytoplasm, and how membrane surface area impacts bacterial size.

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.

Viruses: Bacteriophage Lytic and Lysogenic Cycles

5. 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.

Gram Negative Bacteria: Definition & Examples

6. Gram Negative Bacteria: Definition & Examples

Have you ever wondered what Gram negative bacteria are or, at least, why they are called Gram negative in the first place? This lesson teaches you that and provides some famous examples of Gram negative bacteria.

Gram-Positive Bacteria: Definition & Examples

7. Gram-Positive Bacteria: Definition & Examples

This lesson is positively filled with information about gram-positive bacteria! First, you'll learn why these guys are even called gram positive in the first place. Then, you'll learn about a few examples of some famous gram-positive bacteria.

Acid-Fast Bacteria: Definition & Examples

8. Acid-Fast Bacteria: Definition & Examples

In this lesson, you'll learn the basics of acid fast bacteria. Learn how these bacteria are identified and about the unique structure of their cell walls that classify them as such. By the end, you'll be able to explain some examples important to medicine.

Enteric Bacteria: Definition & Types

9. Enteric Bacteria: Definition & Types

How many bacteria are found in your intestinal tract and what purpose do they serve? Well, take a guess and then read this lesson about enteric bacteria to learn about the staggering amount of bacteria found within the human body.

Pseudomonas Fluorescens: Morphology, Gram Stain & Identification

10. Pseudomonas Fluorescens: Morphology, Gram Stain & Identification

This lesson will discuss characteristics of the bacterium species, Pseudomonas fluorescens, including morphology and Gram stain, which aid in the identification of specific bacterial species.

Pseudomonas Fluorescens: Characteristics, Motility & Habitat

11. Pseudomonas Fluorescens: Characteristics, Motility & Habitat

Microbes are everywhere. In this lesson, we will explore the world of a fascinating bacterium known as Pseudomonas Fluorescens to learn more about how it lives and where it can be found.

Pseudomonas Luteola: Habitat & Identification

12. Pseudomonas Luteola: Habitat & Identification

We live in a world covered with microorganisms. Many of these organisms are good for humans while others can cause serious problems. In this lesson, we will explore the bacterium known as Pseudomonas Luteola.

Pseudomonas Luteola: Morphology, Oxidase Test & Gram Stain

13. Pseudomonas Luteola: Morphology, Oxidase Test & Gram Stain

''Pseudomonas luteola'' is a bacteria that is found often in nature. We'll discuss its morphology and how to identify it using Gram stain, oxidase, and catalase tests.

What is Antimicrobial Resistance? - Definition, Testing & Statistics

14. What is Antimicrobial Resistance? - Definition, Testing & Statistics
