Ch 34: TExES Science 7-12: Cell Reproduction & Division

About This Chapter

Use this chapter to review subject matter you'll need to know regarding cell reproduction and division when taking the TExES Science 7-12 exam. Engaging video lessons are used to present the information.

TExES Science 7-12: Cell Reproduction & Division - Chapter Summary

You should be familiar with the actions involved with cell reproduction and division before your TExES Science 7-12 test. This chapter helps you prepare by reviewing:

  • The definition for genome
  • Chromosomal features
  • Mitosis and meiosis
  • The cell cycle
  • Sexual and asexual reproduction
  • Chromosomal abnormalities
  • Uses of adult and embryonic stem cells

Each facet of cell reproduction and division covered by this chapter is given its own video lesson. These lessons are accompanied by quizzes to ensure you understand the material. If you'd like to look at any particular video segments a second time, you can use the Timeline to make it easier to find them.

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.

Chromosomes: Structure & Physical Features

2. Chromosomes: Structure & Physical Features

You've probably heard about chromosomes before, but how much do you truly know about them? This lesson will discuss their structure and features and will go over all of the vocabulary you need to know to be a chromosome expert!

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.

The Cell Cycle: Definition, Phases & Sequence

4. 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.

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: Comparison to Mitosis, Crossing Over & Process

7. 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.

Nondisjunction & Aneuploidy: Definition & Examples

8. 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.

Embryonic and Adult Stem Cells: Uses, Origins & Properties

9. Embryonic and Adult Stem Cells: Uses, Origins & Properties

How can we grow a brand new windpipe? Or a heart? In this lesson, we'll learn about embryonic and adult stem cells and how scientists are using them to give people a new lease on life.
