Ch 2: Cell Structure

About This Chapter

Use our video lessons and quizzes to help you understand cell structure. Explore types and parts of human cells, among other topics related to the structure of cells.

Cell Structure - Chapter Summary

Our team of experienced professional educators has put together this online chapter to teach you about cell structure. Topics in this series of video lessons include the cell cycle and plant cell structures, including the cell wall and central vacuole. You also can learn about the following areas through this chapter:

  • Eukaryotic and prokaryotic cells: similarities and differences
  • Viruses: bacteriophage lytic and lysogenic cycles
  • Structure of the nucleus: nucleolus, nuclear membrane and nuclear pores
  • The ribosome: structure, function and location
  • The cytoskeleton: microtubules and microfilaments
  • Mitochondria structure: cristae, matrix, and inner and outer membrane
  • Chloroplast structure: chlorophyll, stroma, thylakoid and grana

We make learning about cell structure easy and engaging through the handful of brief video lessons in this chapter. You can watch each lesson in its entirety or use the clickable video tags to jump to main points. If you'd rather read the lesson than watch it, you're in luck; the transcript of each video is included as well.

You can measure your proficiency regarding cell structure through the self-assessment quiz that accompanies each video. To get the most out of these quizzes, take them both before watching the video - to identify areas where you need to pay extra attention - and after - to make sure you've fully absorbed the information presented.

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.

Viruses: Bacteriophage Lytic and Lysogenic Cycles

2. 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.

Structure of the Nucleus: Nucleolus, Nuclear Membrane, and Nuclear Pores

3. Structure of the Nucleus: Nucleolus, Nuclear Membrane, and Nuclear Pores

In this lesson, we'll discuss the organization and importance of the nucleus in your cells. This is the membrane-bound structure responsible for containing all the genetic material essential to making you who you are.

The Ribosome: Structure, Function and Location

4. The Ribosome: Structure, Function and Location

The ribosome is the cellular structure responsible for decoding your DNA. In this lesson, we'll learn about ribosome structure, function and location - characteristics that make it a very good genetic translator.

The Cytoskeleton: Microtubules and Microfilaments

5. The Cytoskeleton: Microtubules and Microfilaments

In this lesson, we'll learn about the cytoskeleton of your cells. This network of microtubules, intermediate filaments, and microfilaments helps different types of cells maintain a unique set of characteristics, including shape and movement.

Mitochondria Structure: Cristae, Matrix and Inner & Outer Membrane

6. Mitochondria Structure: Cristae, Matrix and Inner & Outer Membrane

If you want to make it through the day, you're going to need some energy. In this lesson, we'll learn about the organelle that supplies this energy, the mitochondrion, and why this cell structure appreciates the time you took to eat breakfast this morning!

Chloroplast Structure: Chlorophyll, Stroma, Thylakoid, and Grana

7. Chloroplast Structure: Chlorophyll, Stroma, Thylakoid, and Grana

In this lesson, we'll explore the parts of the chloroplast, such as the thylakoids and stroma, that make a chloroplast the perfect place for conducting photosynthesis in plant cells.

Plant Cell Structures: The Cell Wall and Central Vacuole

8. Plant Cell Structures: The Cell Wall and Central Vacuole

In this lesson, we'll talk about some of the things that make plant cells so different from our cells. In addition to being mean, green photosynthesizing machines, plant cells have cell walls and central vacuoles to make them unique!

The Cell Cycle: Definition, Phases & Sequence

9. The Cell Cycle: Definition, Phases & Sequence

Learn about the dividing and non-dividing states of the cell and discover the different phases of the cell cycle, including interphase, cytokinesis, and the stages of cell division.
