About This Chapter
Prokaryotic & Eukaryotic Cells - Chapter Summary
In this chapter, our professional instructors will discuss the characteristics of prokaryotic and eukaryotic cells, as well as the structures and functions of one particular type of prokaryotic cell, bacteria. Watch these lessons to improve your understanding of:
- How eukaryotic cells organize and specialize to create organelles and prokaryotic cells don't
- Structures and functions of bacterial cell membrane and cytoplasm
- Properties and structures of bacterial cell walls
- Different external structures of bacteria cells and their functions
- Bacterial DNA and the bacterial genome
- Bacterial plasmids and how they affect bacterial DNA
You could also read the lesson transcripts for a written overview of the material. Study the key vocabulary words of the chapter and improve your retention of the information presented in the video lessons.
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.
