9 Lessons in Chapter 6: TExES Life Science: Prokaryotic Cells
Eukaryotic and Prokaryotic Cells: Similarities and Differences

1. Eukaryotic and Prokaryotic Cells: Similarities and Differences

In this lesson, we discuss the similarities and differences between the eukaryotic cells of your body and prokaryotic cells such as bacteria. Eukaryotes organize different functions within specialized membrane-bound compartments called organelles. These structures do not exist in prokaryotes.

Bacterial Cytoplasm & Cell Membrane: Structure & Components

2. 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.

Bacterial Cell Walls: Structure, Function & Types

3. 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 Structures and Their Functions

4. Bacterial Structures and Their Functions

A bacterial cell is not smooth like a balloon. Bacteria can be covered with a wide range of structures like pili and capsules that give each species of bacteria different abilities. In this lesson, you will learn about several of these key external structures of bacteria.

The Bacterial Genome: Structure & Organization

5. The Bacterial Genome: Structure & Organization

All organisms have DNA. While the basic structure of DNA is the same, the organization of the DNA in bacterial cells is very different than in human or animal cells. In this lesson we will explore the basics of the bacterial genome.

Bacterial Plasmids: Definition, Function & Uses

6. Bacterial Plasmids: Definition, Function & Uses

What if you could pick up bits of DNA and change your traits? In the animal kingdom, organisms are born with their lifetime total of DNA. In the bacterial world, cells can add to their genome by acquiring plasmids.

Aerobic Bacterial Metabolism: Definition & Process

7. Aerobic Bacterial Metabolism: Definition & Process

Respiration is the process of converting nutrients into usable energy. Several different mechanisms exist in the bacterial world. In this lesson, we will examine the role of oxygen in bacterial aerobic respiration.

Anaerobic Bacterial Metabolism: Definition & Process

8. Anaerobic Bacterial Metabolism: Definition & Process

Bacteria are metabolically versatile and can grow in a range of environments. Many bacteria grow in environments without oxygen using anaerobic respiration and fermentation. This lesson will discuss the process of anaerobic respiration in bacteria.

Bacterial Fermentation Process & Products

9. Bacterial Fermentation Process & Products

Bacteria in anaerobic environments can break down organic compounds using fermentation. If you have ever eaten a fermented food, such as bread, yogurt or cheese, you have tasted the products of fermentation. Now, learn the details of this process.
