22 Lessons in Chapter 12: GED Science - Cell Biology: Help and Review
How a Phospholipid Bilayer Is Both Hydrophobic and Hydrophilic

1. 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

2. 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.

Passive Transport in Cells: Simple and Facilitated Diffusion & Osmosis

3. 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.

Active Transport in Cells: Definition & Examples

4. 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!

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.

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.

The Ribosome: Structure, Function and Location

7. 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

8. 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

9. 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

10. 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

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!

Eukaryotic and Prokaryotic Cells: Similarities and Differences

13. 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

14. 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.

Nuclear Envelope: Definition, Function & Structure

15. Nuclear Envelope: Definition, Function & Structure

The nuclei of eukaryotic cells are separated from the cytosol by the nuclear envelope. In this lesson, we explore the structure of the nuclear envelope and the functions it performs in cells.

Double Fertilization in Angiosperms: Definition & Process

16. Double Fertilization in Angiosperms: Definition & Process

You may already know that fertilization is when an egg and sperm cell fuse to create a new individual, but do you know what double fertilization is? It is a process that is unique to angiosperms, and you can learn about it in this lesson.

Extracellular: Definition & Structures

17. Extracellular: Definition & Structures

Extracellular isn't just a way to refer to the outside of the cell: there's a whole lot going on out there that has to do with the growth, work, and ultimately the survival of the cell -- the tiniest part of life.

Methionine: Structure, Production & Benefits

18. Methionine: Structure, Production & Benefits

Have you ever heard of the amino acid methionine? In this lesson you will learn about the structure, production and benefits of methionine. After learning about methionine, you can check your understanding by taking a quiz.

Microfilaments: Definition, Function & Structure

19. Microfilaments: Definition, Function & Structure

Microfilaments are present in all cells that we encounter. They allow for movement, structure, and transportation across a cell. These filaments are important in each type of cell - we will go into greater detail in this lesson.

Stroma Cells: Definition & Function

20. Stroma Cells: Definition & Function

There are many different types of tissue found in animals. One such tissue, stroma, are very basic yet essential to our survival. These stroma cells help our internal organs and allow us to live and function. We will talk about these here.

Do Animal Cells Have a Cell Membrane

21. Do Animal Cells Have a Cell Membrane

What are cell membranes and what do they do? Better yet, do animal cells even have them? This lesson answers those questions through an investigation into cell membranes. A lesson summary and brief quiz are included.

Adherent & Suspension Cell Cultures

22. Adherent & Suspension Cell Cultures

One cell likes to anchor itself to the surface, while another enjoys free-floating in solution. Use this lesson to learn about two basic cell types encountered in cell culture: adherent and suspension cell cultures.
