MTEL Biology: Cell Reproduction and Division - Chapter Summary
You can use the lessons we provide in this chapter to review what you learned in college about cell reproduction and division as you prepare for the MTEL Biology Exam. The videos cover all the content you need to know, including:
- DNA packaging and chromosome condensation
- The cell cycle
- Asexual vs. sexual reproduction
- Stem cells and aneuploidy
- Reductional and equational cell division in meiosis
Our expert instructors guide you through each topic, pointing out the key points you need to remember for the test. The chapter includes entertaining videos, informative transcripts and video tags that let you conveniently move from one main topic to the next.
Objectives of the MTEL Biology: Cell Reproduction and Division Chapter
The MTEL Biology Exam is a standardized test that assesses knowledge and comprehension of all of biology. Questions on this chapter's subject matter will be found in the exam's Chemistry of Life and Cell Biology section. There will be 16-18 multiple-choice items on this objective of the test. By taking the self-assessment quizzes, you can determine what you know and what you still have to study, plus, you'll get exposure to the types of questions that will appear on the actual exam.
The questions on the MTEL Biology Exam are a combination of 100 multiple-choice and 2 open-response items. These items evaluate your ability to integrate your knowledge and understanding of biology in a logical, organized, articulate essay.
1. 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!
2. 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.
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.
4. 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.
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.
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.
7. 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.
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.
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.
