Ch 7: ILTS Biology: Cell Cycle & Division

About This Chapter

Refresh your understanding of how cells propagate with the information in this chapter. Our study guide offers video lessons, self-assessment quizzes and other tools you'll need to tackle the ILTS Biology exam.

ILTS Biology: Cell Cycle and Division - Chapter Summary

The video lessons in this chapter can help you to remember how cells reproduce, with information on physical structures and processes as well as uses for stem cells. Concepts covered here will aid in answering ILTS Biology questions on topics that include:

  • Chromosomes
  • Genomes
  • DNA packaging
  • The cell cycle
  • Mitosis
  • Sexual and asexual reproduction
  • Cytokinesis in plant and animal cells
  • Meiosis
  • Nondisjunction and aneuploidy

Our expert instructors will help you prepare for the exam with enjoyable video lessons that you can study on the go via smartphone or tablet. You can ensure you have a solid grasp of the main points by reviewing a text transcript of the video. You can even ask questions of the instructors through our message board.

ILTS Biology: Cell Cycle and Division Chapter Objectives

To become a certified biology teacher in the state of Illinois, you must pass the computer-based ILTS Biology exam. The subjects of this Cell Cycle and Division chapter are incorporated into the life science area of the ILTS Biology test.

Both our lesson quizzes and the ILTS test are multiple-choice, so completing the quizzes will give you a good idea of the types of questions you'll encounter on the exam. The quizzes also let you assess your learning and see where you need extra review. You will have three hours and 45 minutes to answer 125 questions.

Test your knowledge with a 30-question chapter practice test
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.

Overview of Mitosis: Mitotic Spindle & Phases of Chromosome Segregation

5. Overview of Mitosis: Mitotic Spindle & Phases of Chromosome Segregation

Have you ever wondered how we grow? We start off as tiny embryos that eventually develop into adult humans, but how? The answer is through mitosis. We will look at mitosis and some specifics of it here.

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.

Asexual vs. Sexual Reproduction: Comparison & Characteristics

7. 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.

Overview of Reductional & Equational Cell Division in Meiosis

8. Overview of Reductional & Equational Cell Division in Meiosis

This lesson is going to give a general overview of the two divisions that take place during meiosis. We will take a look at why these divisions are referred to as reductional and equational division.

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.

Embryonic and Adult Stem Cells: Uses, Origins & Properties

10. 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.
