Ch 13: GED Science - The Cell Cycle and Cell Division: Help and Review

About This Chapter

The Cell Cycle and Cell Division chapter of this GED Science Help and Review course is the simplest way to master the cell cycle and cell division. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of the cell cycle and cell division.

Who's it for?

Anyone who needs help learning or mastering GED science material will benefit from taking this course. There is no faster or easier way to learn GED science. Among those who would benefit are:

  • Students who have fallen behind in understanding chromosomes or the cell division process
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about the cell cycle and cell division
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science 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 cycle and cell division 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 cycle and cell division chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any cell cycle or cell division question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students will review:

This chapter helps students review the concepts in a cell cycle and cell division unit of a standard GED science course. Topics covered include:

  • The genome and its components
  • Chromosome structure
  • Mitosis I and mitosis II
  • Asexual and sexual reproduction
  • Meiosis I and meiosis II

17 Lessons in Chapter 13: GED Science - The Cell Cycle and Cell Division: Help and Review
Basic Genetics: The Genome & Chromosomes

1. Basic Genetics: The Genome & Chromosomes

There are approximately 3 billion bases in the human genome. In this lesson, you'll learn more about the genome and its organization into chromosomes. We think about DNA often as the blueprint for life, but we can also think of it as the recipe for life with the nucleus being the library.

How is DNA Organized into Chromosomes? - Structure & Function

2. How is DNA Organized into Chromosomes? - Structure & Function

Explore the structure of chromosomes and see how DNA fits inside the nucleus of the cell. In this lesson, you'll learn about histones, chromatin and nucleosomes.

The Cell Cycle: Definition, Phases & Sequence

3. 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.

How is DNA Packaged? - Chromosome Condensation & Karyograms

4. 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.

Parts of a Chromosome & Their Roles

5. Parts of a Chromosome & Their Roles

Learn all about chromosomes, including the different parts of a chromosome and the types of chromosomes in diploid organisms like humans. Learn the vocab used with chromosomes.

Mitotic Spindle: Definition, Formation & Function

6. 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

7. 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

8. 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

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.

Meiosis: Comparison to Mitosis, Crossing Over & Process

10. Meiosis: Comparison to Mitosis, Crossing Over & Process

Welcome to meiosis, a realm of division doubled for reproduction untroubled. You'll get a preview of both divisions of meiosis and see what it takes to go from a diploid cell to a haploid gamete.

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

11. 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

12. 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

13. 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.

Channel Protein: Definition & Function

14. Channel Protein: Definition & Function

In this lesson, you will learn the definition of a channel protein, as well as how those proteins assist in transporting material across the cell membrane. Afterwards, test your understanding with a quiz.

Aneuploidy: Definition & Disorders

15. Aneuploidy: Definition & Disorders

This lesson will define aneuploidy, what it is and what it means. The lesson will also identify some of the disorders associated with aneuploidy and how they come about.

Gametogenesis: Definition & Concept

16. Gametogenesis: Definition & Concept

Birds do it, bees do it, even educated fleas do it. Let's do it, let's make some gametes. This lesson discusses how sperm and egg are produced and why these cell types are different from any other cell in your body.

The G0 Phase of the Cell Cycle

17. The G0 Phase of the Cell Cycle

What are the parts of the cell cycle? In which part of the cycle does a cell spend most of its time? In this lesson you will learn about the G0 phase of the cell cycle and why it is so important to the overall health of an organism.
