About This Chapter

The Cell Structure and Function chapter of this Holt McDougal Modern Biology textbook companion course helps students learn essential modern biology lessons on cell structure and function. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Cell Structure and Function textbook chapter.

How it works:

  • Identify the lessons in the Holt McDougal Modern Biology Cell Structure and Function chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the cell structure and function topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • The cell theory
  • Similarities and differences between eukaryotic and prokaryotic cells
  • Properties of the phospholipid bilayer
  • The fluid-mosaic model of the cell membrane
  • Structures of the nucleus
  • Structures of the mitochondria
  • Structure and function of ribosomes
  • Functions and components of the endomembrane system

Understanding Cell Biology: History & Theories

1. Understanding Cell Biology: History & Theories

The study of cells is one of the fields most crucial to understanding biology, even though it is a relatively new field. Here we will go through a brief history of cell biology and examine its key theories.

What are Cells? - Overview

2. What are Cells? - Overview

All living organisms are made up of cells, but do you know what a cell is? In this lesson, you can learn about the three main structures that all cells contain and about the two major types of cells.

Eukaryotic and Prokaryotic Cells: Similarities and Differences

3. 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.

How a Phospholipid Bilayer Is Both Hydrophobic and Hydrophilic

4. How a Phospholipid Bilayer Is Both Hydrophobic and Hydrophilic

In this lesson, we will learn what gives phospholipids a dual personality. How can this molecule be both hydrophobic and hydrophilic, and why is this important to a cell?

The Fluid Mosaic Model of the Cell Membrane

5. The Fluid Mosaic Model of the Cell Membrane

In this lesson, we will discuss the components of the cell membrane and why the fluid mosaic model paints the best picture of its structure. We'll learn about the roles of the phospholipid bilayer, cholesterol, proteins and carbohydrates.

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

6. 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.

Mitochondria Structure: Cristae, Matrix and Inner & Outer Membrane

7. 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!

The Ribosome: Structure, Function and Location

8. 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 Endomembrane System: Functions & Components

9. The Endomembrane System: Functions & Components

In this lesson, we'll learn about the endomembrane system, which consists of the endoplasmic reticulum and the Golgi apparatus. This system is important in making, packaging, and shipping all sorts of goodies for the cell to use!

The Cytoskeleton: Microtubules and Microfilaments

10. 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.

Chloroplast Structure: Chlorophyll, Stroma, Thylakoid, and Grana

11. 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

12. 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!
