About This Chapter

The Cell Biology chapter of this AP Biology Tutoring Solution is a flexible and affordable path to learning about cell biology. These simple and fun video lessons are each about five minutes long and they teach all of the information involving cell biology required in a typical AP biology course.

How it works:

  • Begin your assignment or other biology work.
  • Identify the cell biology concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our AP biology tutoring solution will benefit any student who is trying to learn cell biology and earn better grades. This resource can help students including those who:

  • Struggle with understanding passive and active cell transport, structure of the nucleus, viruses or any other cell biology topic
  • Have limited time for studying
  • Want a cost effective way to supplement their science learning
  • Prefer learning science visually
  • Find themselves failing or close to failing their AP biology - cell biology unit
  • Cope with ADD or ADHD
  • Want to get ahead in AP biology
  • Don't have access to their science teacher outside of class

Why it works:

  • Engaging Tutors: We make learning cell biology simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live biology tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn cell biology on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

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

In this lesson, we'll learn more about this self-taught scientist, including some of his important discoveries and unique way of presenting his work.

Endoplasmic Reticulum: Definition & Functions

16. Endoplasmic Reticulum: Definition & Functions

Cells are made of numerous organelles that perform specific functions. In this lesson, you will learn about the structure and functions of the endoplasmic reticulum.

Intermediate Filaments: Definition, Function & Structure

17. Intermediate Filaments: Definition, Function & Structure
