Ch 70: MTEL Middle School Math/Science: Cell Division

About This Chapter

Rediscover the inner workings of a cell with our chapter on cell division as you prepare to take the MTEL Middle School Math/Science exam. Our lessons form a powerful tool that will help you effectively answer the questions on the test.

MTEL Middle School Math/Science: Cell Division - Chapter Summary

Get ready for the MTEL Middle School Math/Science exam's questions. In this chapter, you will review the basic processes of how and why cells divide, DNA replication, chromosome structure and development, and more. The material covered in the videos is listed below:

  • Chromosomes and the cell cycle
  • Chromosome condensation and physical features
  • Mitosis and meiosis I and II
  • Reproduction at the cellular level
  • Equational and reductional cell division
  • Chromosome segregation and Down Syndrome

Our lesson instructors have solid credentials in their fields of expertise, and their knowledge is accessible to you. Our videos provide you with the opportunity to ask questions or seek clarification after each lesson, and our subject area specialists are available for additional consultation if you so desire. Further, the mobile nature of our platform enables you to use our program from any location that offers Internet access.

MTEL Middle School Math/Science: Cell Division Objectives

The primary objective of the MTEL Middle School Math/Science exam is to measure the subject-area expertise of candidates seeking teacher certification. Our lessons on cell division address Subarea IX: Biology. The biology subarea is weighted at 8%.

The MTEL Middle School Math/Science test is a computer-based examination with 100 multiple-choice questions and two open-ended response assignments. The former comprises 80% of the score, with the remaining 20% being the two final questions.

How is DNA Organized into Chromosomes? - Structure & Function

1. 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

2. 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

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.

Parts of a Chromosome & Their Roles

4. 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

5. 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

6. 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.

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.

Meiosis: Comparison to Mitosis, Crossing Over & Process

8. 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

9. 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

10. 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

11. 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.
