About This Chapter
Washington EOC Biology Grade 10: Cell Biology - Chapter Summary
Reviewing the lessons in this chapter simplifies the process of studying for the Washington EOC Biology Grade 10 test. No matter your current knowledge of cell biology, this chapter gets you up to speed so you're able to answer questions that ask you to:
- Discuss the structure and function of the cell and cell membrane
- Explain how a phospholipid bilayer is both hydrophobic and hydrophilic
- Describe the fluid mosaic model of the cell membrane and endocytosis and exocytosis across the cell membrane
- Provide details about passive and active transport in cells and the function, structure and composition of the plant cell wall
- Share information about the structure of the nucleus, chloroplast, mitochondria and ribosome
- Define chromosomes, cytoplasm and central vacuole in plant cells
The majority of lessons in this chapter are available as videos and full transcripts. Review the lessons in any format you choose from your computer or mobile devices. If you decide to review the videos, take advantage of timelines that allow you to identify and skip to key topics without watching the lessons in full. At any time, take short quizzes and the chapter exam to test your comprehension of cell biology.
1. The Cell: Structure & Function
The cell is a small, but complex structure. Take a look inside the outer plasma membrane of a cell and discover the functions of some common cellular components, including the nucleus, endoplasmic reticulum, Golgi apparatus and mitochondria, in this lesson.
2. Cell Membrane: Functions, Role & Structure
You are made up of trillions and trillions of cells, and each one is separated from its surroundings by a cell membrane. Learn about the structure and functions of the cell membrane in this lesson.
3. 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?
4. 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.
5. 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.
6. 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!
7. 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.
8. Plant Cell Wall: Function, Structure & Composition
All cells have a cell membrane on the outside of them that acts like a skin. Plant cells go one step further and have a cell wall - a protective outside that provides support and other functions.
9. 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.
10. What Are Chromosomes? - Definition, Function, Types & Structure
In this lesson, you'll find out why primates look so human while learning about the different types of chromosomes and how they work. You'll also get a chance to see what a chromosome looks like and discover how many genes are found in the human body.
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.
12. 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!
13. 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.
14. What is Cytoplasm? - Definition & Functions
Did you know your cells are filled with a thick fluid? Cytoplasm is an important part of your cells and serves several functions that are key to cellular health and productivity.
15. Central Vacuole in Plant Cells: Definition & Function
Plant cells are composed of numerous organelles that work together in all aspects of the plant's life. In this lesson, you will learn about the central vacuole of plant cells.
