Anyone who needs help learning or mastering cell structure and cycles material will benefit from the lessons in this chapter. There is no faster or easier way to learn about cell structure and cycles. Among those who would benefit are:

  • Students who have fallen behind in understanding cell structures, internal cell functions, or the cell cycle
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning biology (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about cell structure and cycles
  • Students who struggle to understand their teachers
  • Students who attend schools without extra biology learning resources

How It Works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Cell Structures & Cycles chapter exam.

Why It Works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the Cell Structures & Cycles chapter exam to be prepared.

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.

The Cell Cycle: Definition, Phases & Sequence

15. The Cell Cycle: Definition, Phases & Sequence

Learn about the dividing and non-dividing states of the cell and discover the different phases of the cell cycle, including interphase, cytokinesis, and the stages of cell division.

Cytoskeletal Proteins: Types & Function

16. Cytoskeletal Proteins: Types & Function

In this lesson learn about the skeleton of the cell, called the cytoskeleton. Then explore the three main types of proteins that make up the cytoskeleton: microfilaments, intermediate filaments, and microtubules, and the function of each.
