Ch 6: CEOE Middle Level Science: Cell Biology

About This Chapter

Reinforce what you know about cell structures and functions with these video lessons and quizzes. These types of questions appear in the Life Science section of the Certification Examinations for Oklahoma Educators (CEOE) Middle Level Science exam.

CEOE Middle Level Science: Cell Biology - Chapter Summary

You will use the lessons in this chapter to review or learn new information about cell components and their functions. The narrative text is supported by helpful illustrations to enhance the learning experience. After this review, you should possess the knowledge needed to correctly answer cell biology questions on the CEOE Middle Level Science exam. For instance, you could be capable of:

  • Explaining the structure of mitochondria
  • Detailing the structure of the nucleus
  • Describing the cell's fluid mosaic model
  • Identifying the layers of phospholipids
  • Discussing the processes of endocytosis and exocytosis
  • Summarizing the functions of the ribosome and endomembrane system
  • Providing details about the characteristics of the cytoskeleton of cells

Complex topics are presented with easy-to-follow language and examples. The accompanying quizzes will assess your understanding of the material and gauge your readiness in taking the CEOE Middle Level Science exam by using the same multiple-choice format as is found on the actual test.

Mitochondria Structure: Cristae, Matrix and Inner & Outer Membrane

1. 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!

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

2. 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 Fluid Mosaic Model of the Cell Membrane

3. 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.

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?

Endocytosis and Exocytosis Across the Cell Membrane

5. Endocytosis and Exocytosis Across the Cell Membrane

In this lesson, we'll discover how some cells can eat, drink, and digest their dinner through the process of endocytosis and a structure called the lysosome. In addition, we'll learn how a cell can throw out the leftovers across the cell membrane during exocytosis.

The Ribosome: Structure, Function and Location

6. 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

7. 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

8. 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.
