Ch 3: The Cell Cycle, Mitosis & Meiosis

About This Chapter

Learn about the cell cycle, mitosis, and meiosis, including topics like the phases of chromosome segregation, the differences between cell cycle and mitosis, and the production of haploid gametes. These brief lessons are great for individuals preparing for an exam.

The Cell Cycle, Mitosis & Meiosis - Chapter Summary

In these lessons, you'll learn about the cell cycle, mitosis, and meiosis. Topics covered include reductional cell division, chromosome segregation, and equational cell division. The cytokinesis phase of the cell cycle is also discussed. After completing the chapter, you should be able to do the following:

  • Discuss the cell cycle, including dividing and non-dividing states
  • Explain the stages and function of mitosis
  • Describe the difference between cell cycle and mitosis
  • Explore the mitotic spindle
  • Detail phases of chromosome segregation
  • List steps of meiosis
  • Recognize the difference between meiosis I and meiosis II

Our subject-matter experts present the information in these short video lessons using plenty of examples to ensure the concepts are easy to understand. You can review all the lessons in order, or just look at the ones that cover the topics you need to review. A brief multiple-choice quiz is available for each lesson to test your knowledge. You can also print the lesson quizzes and use them as worksheets.

The Cell Cycle: Definition, Phases & Sequence

1. 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.

What is Mitosis? - Definition, Stages & Function

2. What is Mitosis? - Definition, Stages & Function

Every day your body cells are dividing using a process called mitosis. This allows you to grow and replace damaged or worn out cells. Learn about the stages of mitosis: prophase, metaphase, anaphase and telophase.

Difference Between Cell Cycle and Mitosis

3. Difference Between Cell Cycle and Mitosis

In this lesson, we'll learn the definitions of the cell cycle and of mitosis and go over the different steps involved in each. We'll also take a look at what happens to our cells and our bodies when these processes go wrong.

Mitotic Spindle: Definition, Formation & Function

4. Mitotic Spindle: Definition, Formation & Function

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

Stages of Mitosis: Description & Sequence

5. Stages of Mitosis: Description & Sequence

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.

What is Meiosis? - Steps & Results

6. What is Meiosis? - Steps & Results

It's meiosis that gives us the male and female reproductive cells known as the egg and sperm. In meiosis, two cell divisions take place, which produces four genetically unique cells with half the number of chromosomes as the parent cell.

Meiosis I Stages: Prophase I, Metaphase I, Anaphase I & Telophase I

7. Meiosis I Stages: Prophase I, Metaphase I, Anaphase I & Telophase I

How does meiosis keep track of homologs and reduce the genome by half? Know these answers and more as we navigate the steps of meiosis I. This lesson will be tetradical!

Meiosis II: Definition, Stages & Comparison to Meiosis I

8. Meiosis II: Definition, Stages & Comparison to Meiosis I

Behold round two of meiotic cell division! You'll see how meiosis II keeps the genome intact and gives the final push to produce haploid gametes, which make the world go round.
