About This Chapter
Who's it for?
This unit of our High School Biology Homeschool course will benefit any student who is trying to learn about protocols and applications in bacterial biology. There is no faster or easier way to learn about biology. Among those who would benefit are:
- Students who require an efficient, self-paced course of study to learn about bacterial plasmids, conjugation and transformation.
- Homeschool parents looking to spend less time preparing lessons and more time teaching.
- Homeschool parents who need a biology curriculum that appeals to multiple learning types (visual or auditory).
- Gifted students and students with learning differences.
How it works:
- Students watch a short, fun video lesson that covers a specific unit topic.
- Students and parents can refer to the video transcripts to reinforce learning.
- Short quizzes and a Bacterial Biology unit exam confirm understanding or identify any topics that require review.
Bacterial Biology Unit Objectives:
- Learn about the classification and morphology of bacterial cells.
- Discuss the formation of bacterial endospores.
- Learn about the processes involved in anaerobic bacterial metabolism.
- Study the structure, function and types of bacterial cell walls.
- Discover the advantages of bacterial transduction.
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!
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.
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.
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.
5. Bacterial Endospores: Definition & Formation
Some bacteria have the ability to enter a state of suspended animation when conditions are unfavorable. In this lesson, we will examine the bacterial endospore and learn how and why bacteria produce these structures.
6. 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.
7. 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.
8. Bacterial Conjugation: Definition & Protocol
You probably didn't know that bacteria can engage in sexual reproduction. It is not what you think. In this lesson we will explore the process of bacterial conjugation and its impact on genetic variability in bacteria.
9. Bacterial Transformation: Definition, Process & Applications
DNA is all around you. So are bacteria. Did you know that those bacteria can pick up and use that DNA? In this lesson we will examine the process of transformation and how bacteria are able to make use of environmental DNA.
10. Bacterial Transduction: Definition, Process & Advantages
Genetic diversity allows organisms to adapt to changing environmental conditions. In this lesson, we will explore bacterial transduction and how it allows bacteria to transfer genes and increase genetic diversity.
11. 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.
12. 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.
13. 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.
14. Escherichia coli (E. coli) as a Model Organism or Host Cell
A model organism can help scientists perform faster and more efficient biological research. This lesson examines the most utilized model organism, E. coli, and looks at the major characteristics that make it a perfect model.
15. Growth Requirements of E. coli and Auxotrophs
Escherichia coli is a normal inhabitant of your gastrointestinal tract. In this lesson we will examine the conditions required for optimal growth of E. coli both in your colon and in culture.
