Ch 10: Mitosis & Meiosis Overview

About This Chapter

Improve your understanding of mitosis and meiosis with this overview that includes asexual reproduction versus sexual reproduction, examples of diploid cells, medical advancements, and more. These brief lessons are a convenient resource for individuals preparing for an exam or getting caught up on missed classroom time.

Mitosis & Meiosis Overview - Chapter Summary

The lessons in this chapter provide an overview of mitosis and meiosis. You will review different ways organisms can reproduce and identical versus fraternal twins. You will also gain an understanding of reductional and equational cell division. After completing the chapter, you should be prepared to:

  • Discuss the role haploid cells play in life cycles
  • Explain how diploid cells keep future cells healthy
  • Provide examples of polyploidy in plants and humans
  • Discuss the mitotic spindle
  • Recall how cytokinesis is different in plant and animal cells
  • Describe the process of nondisjunction in meiosis
  • Explain the biology behind the myths of sex determination
  • Recount medical advancements related to cell division

There is a brief quiz for each lesson that will help to determine how much of the content and details you have retained. Video timelines let you review only the topics you need to review. You can make the most of this helpful resource by printing the quiz in worksheet form to study offline.

Haploid: Definition, Life Cycle & Example

1. Haploid: Definition, Life Cycle & Example

This lesson addresses the concept of haploid cells. It describes haploid cells and the role they play in various life cycles. Illustrations, real-world examples, and a brief quiz are included.

Diploid Cell: Definition & Examples

2. Diploid Cell: Definition & Examples

Diploid cells are the most numerous cells in all living things - plants and animals. In this lesson, you will learn why they're important for life to continue and how they keep future cells healthy.

Polyploidy: Definition & Types

3. Polyploidy: Definition & Types

In this lesson, we introduce the concept of polyploidy and its base term ploidy. We'll discuss different types of ploidy and see some examples of polyploidy in plants, animals, and humans.

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.

Cytokinesis: Animal Versus Plant Cells

6. 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.

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.

Asexual vs. Sexual Reproduction: Comparison & Characteristics

9. Asexual vs. Sexual Reproduction: Comparison & Characteristics

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.

Nondisjunction in Meiosis: Definition & Examples

10. Nondisjunction in Meiosis: Definition & Examples

Nondisjunction during meiosis produces eggs or sperm cells that don't have the normal number of chromosomes. In this lesson, learn about the process of nondisjunction and problems it can cause in humans.

Determination of Sex and Identical vs. Fraternal Twins

11. Determination of Sex and Identical vs. Fraternal Twins

Have you ever heard an old wives' tale about what determines whether a child will be a boy or a girl or what causes twins to be born? In this lesson, we will explore the biology behind these myths on how sex is determined and how twins are created.

Cell Division: Medical Advancements & Technology

12. Cell Division: Medical Advancements & Technology

In this lesson, we will be going over the applications of cell division. If you've ever wondered what goes on in a biomedical research lab, this lesson is for you. Here, we'll talk about biotechnology using cell division that has helped improve the human condition.
