Ch 9: AP Biology - Cell Division: Help and Review

About This Chapter

The Cell Division chapter of this AP Biology Help and Review course is the simplest way to master how cells divide. 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 cell division.

Who's it for?

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

  • Students who have fallen behind in understanding chromosomes and cell division
  • 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 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 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 division chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any 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 division unit of a standard AP Biology course. Topics covered include:

  • The genome
  • Chromosomal characteristics and structure
  • DNA packaging
  • Cytokinesis
  • Mitosis and meiosis
  • Aneuploidy and nondisjunction

Basic Genetics: The Genome & Chromosomes

1. Basic Genetics: The Genome & Chromosomes

Genomes are the DNA content of a cell, and DNA is organized into chromosomes. Learn about basic genetics, such as genomes and chromosomes, gametes, homologous chromosomes, and diploid complements.

How is DNA Organized into Chromosomes? - Structure & Function

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

DNA is organized into chromosomes and even further organized within those chromosomes. Explore the structure of chromosomes, the function of DNA, and learn about genes and their role in DNA.

The Cell Cycle: Definition, Phases & Sequence

3. The Cell Cycle: Definition, Phases & Sequence

The lifetime of a cell is described as the cell cycle. Learn about the definition of the cell cycle and explore the phases and sequence of the cell cycle.

How is DNA Packaged? - Chromosome Condensation & Karyograms

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

Discover how DNA is packaged by understanding how chromosomes condensation and karyograms work. Explore DNA packaging, cell division, histone modification, chromatin packaging, and karyograms.

Parts of a Chromosome & Their Roles

5. Parts of a Chromosome & Their Roles

Chromosomes are made of a number of multiple parts with different roles. Learn about the parts of a chromosome and their function, including the centromere, chromosomal arm, and telomere.

Mitotic Spindle: Definition, Formation & Function

6. Mitotic Spindle: Definition, Formation & Function

Explore the definition of mitotic spindle as well as its formation and function. Learn about the parts of the mitotic spindle, including microtubules, centrosomes, astral and kinetochore microtubules, and chromosome movement.

Stages of Mitosis: Description & Sequence

7. Stages of Mitosis: Description & Sequence

Mitosis is a continuous process with five different stages: prophase, prometaphase, metaphase, anaphase, and telophase. Explore detailed descriptions of the different stages of mitosis.

Cytokinesis: Animal Versus Plant Cells

8. Cytokinesis: Animal Versus Plant Cells

Cytokinesis is a natural process that occurs when a plant or animal cell is divided into two new daughter cells. The process is constantly repeated to create new cells. Learn about cytokinesis and the difference between animal cell division and plant cell division.

Asexual vs. Sexual Reproduction: Comparison & Characteristics

9. Asexual vs. Sexual Reproduction: Comparison & Characteristics

Organisms reproduce in two indifferent ways. Explore a comparison of the characteristics of asexual versus sexual reproduction and discover the differences between mitosis and meiosis.

Meiosis: Comparison to Mitosis, Crossing Over & Process

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

Meiosis and mitosis describe the processes in which cells divide to create new cells. Learn about the similarities and differences between meiosis and mitosis, meiotic recombination, and the various stages of meiosis.

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

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

In Meiosis I, the number of chromosomes in cells is reduced by one-half. Learn about the different stages of Meiosis I, including Prophase I, Metaphase I, Anaphase I, and Telophase I.

Meiosis II: Definition, Stages & Comparison to Meiosis I

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

Learn about the definition and stages of meiosis II and how it compares to meiosis I. Compare the types of cell division during meiosis I with that of meiosis II, and take a closer look at the five stages of meiosis II.

Nondisjunction & Aneuploidy: Definition & Examples

13. Nondisjunction & Aneuploidy: Definition & Examples

Nondisjunction occurs when homologs or chromatids fail to separate during a phase of mitosis or meiosis, while an aneuploidy is a cell with an abnormal number of chromosomes. Explore the definitions and find examples of nondisjunction and aneuploidy.

Centrosome: Definition & Function

14. Centrosome: Definition & Function

Within a cell, structures such as centrosomes have several purposes and functional responsibilities in cellular function. Learn about the definition of centrosomes, their role and function in cell division, and some useful vocabulary.

Sister Chromatids: Definition & Concept

15. Sister Chromatids: Definition & Concept

Sister chromatids play a very important role in mitosis. Understand the definition and concept of sister chromatids; examine the difference between chromatin, chromosomes, and chromatid; chromatids vs. homologous pairs; and explore sister chromatids in mitosis and meiosis.

Chromosome Banding: Definition & Techniques

16. Chromosome Banding: Definition & Techniques

Here we will discuss what chromosome banding is. We will also look at several different types of chromosome banding, techniques for chromosome banding, and why one would want to perform chromosome banding.
