About This Chapter
How It Works:
- Identify the lessons in the Holt McDougal Cell Growth & Division chapter with which you need help.
- Find the corresponding video lessons with this companion course chapter.
- Watch fun videos that cover the cell growth and division topics you need to learn or review.
- Complete the quizzes to test your understanding.
- If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.
Students will learn:
- The life cycle of a cell
- The processes of mitosis
- What cytokinesis is
- How cells respond to damage
- Major regulatory factors involving cell division
- The definition for metastasis
- Kinds of stem cells and how they're used
- The difference between asexual and sexual reproduction

1. The Cell Cycle
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.
2. Mitosis I: The Mitotic Spindle
Condensation makes DNA ready / And microtubules hold it steady / A microtubule's a fancy rope / To move the DNA is the hope / From spindle poles they do extend / To align each chromosome in the end
3. Mitosis II: Phases of Chromosome Segregation
Let's take a second look at mitosis and focus on the phases of chromosome segregation. As we concentrate on chromosomes, you'll learn the tricky dance that takes place through all five phases of mitosis.
4. Cytokinesis: Animal Versus Plant Cells
What's a cell to do when it must divide in two? We'll explore cytokinesis and see how the process can differ in important ways when it comes to plant versus animal cells.
5. Internal & External Factors that Regulate Cell Division
Cells can be incredibly active, carrying out processes like growth and division. To coordinate these activities, the cell uses a range of intracellular and extracellular factors.
6. How a Cell Recognizes an Injury
Cells can suffer damage resulting from infection, trauma, or injury. When this happens, cells must decide how to respond for the good of the body. In this lesson, we'll learn how a cell recognizes injury and uses apoptosis, necrosis, and other signals to die or even kill itself.
7. Metastasis: How Cancer Spreads
This lesson will describe the concept of cancer spreading around the body, or metastasis, as well as why it may occur, how it occurs, why it may fail, and how your blood vessels play a critical role in this process.
8. Asexual Versus Sexual Reproduction
Did you know that some organisms can reproduce without a mate? Check out this video lesson on asexual versus sexual reproduction to discover the different ways organisms can reproduce and the main differences between mitosis and meiosis.
9. Binary Fission: Definition, Steps & Examples
Bacteria are all around you, some make you sick, some are helpful. This lesson will examine one way bacteria reproduce called binary fission. It will also give you some examples of bacteria you may encounter.
10. Multicellular Organisms, Tissues and Epithelium
In this lesson on multicellular organisms, you'll take a look at what it actually means to be multicellular and how cells are organized into tissues, organs, and organ systems. This lesson also covers one of the four main tissue types: epithelial tissue.
11. What Is Cell Differentiation? - Process, Importance & Examples
In this lesson, you will learn how your cells become specialized. This specialization of cells allows them to perform different functions and create different parts of your body.
12. Embryonic and Adult Stem Cells: Uses, Origins & Properties
How can we grow a brand new windpipe? Or a heart? In this lesson, we'll learn about embryonic and adult stem cells and how scientists are using them to give people a new lease on life.
