ILTS Biology: Prokaryotic Cells - Chapter Summary
Use this chapter's video lessons to renew your knowledge of prokaryotic and eukaryotic cells, the bacterial genome and bacterial metabolism. We can help you prepare for ILTS Biology exam questions on topics such as:
- Similarities and differences in eukaryotic and prokaryotic cells
- Structure of bacterial cytoplasm, cell membranes and cell walls
- Function of bacterial structures
- The bacterial genome
- Uses of bacterial plasmids
- Aerobic and anaerobic bacterial metabolism
- Process and products of bacterial fermentation
We offer several tools to help you study for the ILTS Biology exam, including lesson quizzes, chapter tests and a comprehensive final exam that help you monitor your learning. A clickable timeline makes it easy to jump back in the lesson to review particular topics, and a written lesson transcript highlights vital terms and phrases.
ILTS Biology: Prokaryotic Cells Chapter Objectives
All Illinois teachers seeking certification to teach biology must pass the ILTS Biology exam. The exam consists of 125 multiple-choice questions and has six subareas. Questions on prokaryotic cells are in the Cell Biology, Heredity, and Evolution subarea.
Our lesson quizzes also consist of multiple-choice questions, so completing them will give you an idea of the format you'll encounter on the exam. Our lessons also give you a chance to gauge your learning and see where you need extra study.
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.
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. 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.
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.
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.
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.
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.
