Ch 7: Cell Cycles

About This Chapter

As you prepare for an upcoming exam or work on your homework, this engaging chapter on cell cycles can help. Made up of concise video lessons that are easy to understand, this chapter is available 24 hours a day on any smartphone, computer or tablet.

Cell Cycles - Chapter Summary

Our professional instructors clearly explain cell cycles in this informative chapter. You'll watch videos about the cell cycle control system, cytokinesis, meiosis and more. These videos are quickly navigated using the timeline feature, making it easy to go back to any of the sections you'd like to review again. The lesson quizzes and chapter test are a handy way to assess your knowledge before you move on to new topics. These lessons can help you achieve the following objectives:

  • Define the cell cycle, its sequence and phases
  • Outline the cell cycle control system
  • Explain how DNA is packaged
  • Describe the stages of mitosis
  • Differentiate between animal cell and plant cell cytokinesis
  • Compare asexual and sexual reproduction
  • Identify meiosis I stages
  • Contrast meiosis I to meiosis II
  • Provide a definition and examples of nondisjunction and aneuploidy

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.

The Cell Cycle Control System

2. The Cell Cycle Control System

The cell cycle is an important process that occurs in your cells. But, it's also important that controls are in place to regulate this cycle. Here, we'll learn about the cell cycle control system and how it ensures proper cell division takes place.

How is DNA Packaged? - Chromosome Condensation & Karyograms

3. How is DNA Packaged? - Chromosome Condensation & Karyograms

Learn how DNA packaging makes it possible to fit approximately seven feet of DNA inside a single cell. You'll see how chromosome condensation helps cells get ready for cell division.

Stages of Mitosis: Description & Sequence

4. 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

5. 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.

Asexual vs. Sexual Reproduction: Comparison & Characteristics

6. 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.

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.

Nondisjunction & Aneuploidy: Definition & Examples

9. Nondisjunction & Aneuploidy: Definition & Examples

Learn why proper chromosome segregation is essential during meiosis. We'll see how having an extra chromosome can lead to Down Syndrome and also examine the consequences of having too few chromosomes. Disruptions to the delicate balance of cell division can have far-reaching effects.
