About This Chapter
Who's it for?
This unit of our AP Biology Homeschool course will benefit any student who is trying to learn about the basics of cellular biology. There is no faster or easier way to learn about cellular anatomy and physiology. Among those who would benefit are:
- Students who require an efficient, self-paced course of study to learn about the structure and function of cells.
- Homeschool parents looking to spend less time preparing lessons and more time teaching.
- Homeschool parents who need a science curriculum that appeals to multiple learning types (visual or auditory).
- Gifted students and students with learning differences.
How it works:
- Students watch a short, fun video lesson that covers a specific unit topic.
- Students and parents can refer to the video transcripts to reinforce learning.
- Short quizzes and a cell biology unit exam confirm understanding or identify any topics that require review.
Cell Biology Unit Objectives:
- Describe the hydrophobic and hydrophilic properties of a phospholipid bilayer.
- Explain the cell membrane in terms of the fluid mosaic model.
- Understand passive transport in cells via facilitated and simple osmosis and diffusion.

- Describe the endomembrane system.
- Explain the structure of the cytoskeleton.
- Understand the structure of the mitochondria.
- Report on the structures of the chloroplast, including thylakoid, chlorophyll, grana, and stroma.
- Identify plant cell structures, including the central vacuole and cell wall.
- Compare and contrast prokaryotic and eukaryotic cells.
- Explain the bacteriophage lytic and lsyogenic cycles of viruses.
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?
2. 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.
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.
4. 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.
5. 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!
6. 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.
7. 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.
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.
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!
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.
11. 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!
12. 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.
13. 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!
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.
