About This Chapter
OAE - Biology: Cell Biology & Cell Cycle - Chapter Summary
These animated video lessons help you review topics related to cell biology and the cell cycle so you'll be ready to answer related questions on the OAE Biology exam. You'll freshen up on the role and functions of cells and take a look at illustrations of key cellular components. After studying this chapter, you'll be prepared to:
- Diagram the fluid mosaic model of the cell membrane
- Distinguish between passive and active transport in cells
- Describe the processes of endocytosis and exocytosis
- Catalogue the components of the nucleus
- Assess the structures and functions of the ribosome and the endomembrane system
- Discuss the roles of microtubules and microfilaments
- Label parts of the mitochondria structure
- Explain the process by which energy is transferred through cells
- Describe how a cell identifies an injury
Our lessons were designed by expert instructors with a passion for making learning easier. Make use of these videos whenever you want, on any of your mobile devices. And before you sit for the Biology OAE, take a gander at our self-assessment quizzes and try out multiple-choices questions close to those you'll face on the exam.
OAE Biology: Cell Biology & Cell Cycle - Chapter Objectives
There are five subareas of the Ohio Assessments for Educators (OAE) Biology exam, totaling 150 questions. This chapter arms you with knowledge about cells to help you answer questions that could appear in the content domain focused on biochemistry and cell biology. This domain constitutes 13% of the OAE Biology exam. You are given three hours to answer all of the multiple-choice questions on the test. Prospective educators must pass the OAE Biology exam in order to teach life sciences to 7th graders and older.
1. 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.
2. Passive Transport in Cells: Simple and Facilitated Diffusion & Osmosis
A cell membrane is selectively permeable - not permeable to everything. In this lesson, we'll talk about methods of passive transport along a concentration gradient, including simple and facilitated diffusion and osmosis.
3. Active Transport in Cells: Definition & Examples
In this lesson, we'll learn how substances are transported across the cell membrane against the concentration gradient. This might seem like an uphill battle for the cell, but all it takes is a little chemical energy and a few integral membrane proteins to kick off some active transport!
4. 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.
5. 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.
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.
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!
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.
9. 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!
10. Cellular Respiration: Energy Transfer in Cells
Watch this short video to learn the basics about converting organic compounds into ATP, also known as cellular respiration. We'll look at an overview of the process.
11. How a Cell Recognizes an Injury
Cells can suffer damage resulting from infection, trauma, or injury. When this happens, cells must decide how to respond for the good of the body. In this lesson, we'll learn how a cell recognizes injury and uses apoptosis, necrosis, and other signals to die or even kill itself.
