Ch 7: MCAS STE Biology: Cell Growth & Reproduction

About This Chapter

Use the lessons in this chapter to review all of the functions involved in cell growth and reproduction so that you can feel prepared to answer relevant questions on the MCAS Science and Technology-Engineering Biology exam.

MCAS STE Biology: Cell Growth & Reproduction - Chapter Summary

The lessons in this chapter will help you prepare for the MCAS STE Biology exam by reviewing the different types of cell reproduction, and the processes involved in each of these types. By the end of this chapter you will have studied:

  • The Cell Cycle
  • Genomes
  • Differences between sexual and asexual reproduction
  • Stages and functions of mitosis
  • How meiosis works
  • Aneuploidy and nondisjunction
  • Fertilization and the formation of zygotes
  • Difference between cells and viruses

The lessons in this chapter have been developed by professional educators to help you understand the material in several different ways. Each lesson contains a video to help illustrate the information as well as its transcript for text-based learning. At the end of each lesson you can take the self-assessment quiz to see how well you can apply your knowledge of the material.

MCAS STE Biology: Cell Growth & Reproduction - Objectives

The MCAS STE Biology exam is taken by high school students in Massachusetts to assess proficiency in biology based on the Massachusetts Curriculum Framework standards. The lessons in this chapter will prepare you for questions about biochemistry and cell biology, which account for 25% of the total score.

The MCAS STE Biology exam is comprised of 40 multiple-choice questions and 5 open-ended response questions. After completing the exam, each student will receive a numeric score that falls into one of four levels of performance: Advanced, Proficient, Needs Improvement or Failing. To be eligible for graduation, you must earn a scaled score of 220 or higher on one of the 4 STE exams.

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.

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.

Asexual vs. Sexual Reproduction: Comparison & Characteristics

3. 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.

What is Mitosis? - Definition, Stages & Function

4. What is Mitosis? - Definition, Stages & Function

Every day your body cells are dividing using a process called mitosis. This allows you to grow and replace damaged or worn out cells. Learn about the stages of mitosis: prophase, metaphase, anaphase and telophase.

What is Meiosis? - Steps & Results

5. What is Meiosis? - Steps & Results

It's meiosis that gives us the male and female reproductive cells known as the egg and sperm. In meiosis, two cell divisions take place, which produces four genetically unique cells with half the number of chromosomes as the parent cell.

Nondisjunction & Aneuploidy: Definition & Examples

6. 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.

Fertilization and Zygote Formation: Definition and Processes

7. Fertilization and Zygote Formation: Definition and Processes

Follow the male's sperm and the female's egg on their way to meet each other in this lesson that takes you through the process of fertilization in humans. Learn about the obstacles the sperm must get through before it can fertilize the egg.

Comparing Cells to Viruses: Genetic Material & Reproduction

8. Comparing Cells to Viruses: Genetic Material & Reproduction

In this lesson, we'll review the definition of both cells and viruses. Then, we'll compare and contrast the genetic material in cells to the different types of genetic material in viruses. Lastly, we'll compare reproductive strategies for both.
