Ch 29: Praxis Biology & General Science: Animal Reproduction and Development

About This Chapter

Let us teach you about animal reproduction and development. The video lessons and self-assessment quizzes in this chapter can help you answer questions about diversity of life, plants and animals on the Praxis II: Biology and General Science test.

Animal Reproduction and Development - Chapter Summary

Get an overview of animal reproduction and development through this chapter, which can help you study for the Praxis II: Biology and General Science test. Watch our short but engaging video lessons to learn how the male and female reproductive systems produce sperm and eggs, respectively. You'll also explore instinct and innate and learned behaviors, including reflexes, kineses, imprinting and habituation. Our professional, knowledgeable educators also address the following topics in this chapter:

  • Early embryonic development
  • Embryo implantation and placenta formation
  • Amniotic fluid, the amnion and the yolk sac
  • Gastrulation and the three germ layers
  • Parthenogenesis and metamorphosis
  • Principles of growth and development
  • Growth, development and aging of animals
  • Animal communication

Animal Reproduction and Development Objectives

If you hope to work as a secondary school science teacher, you might have to pass the Praxis II: Biology and General Science test as part of your state's certification process. This test features 120 multiple-choice questions, approximately 17% of which cover diversity of life, plants and animals; this could include questions about animal reproduction and development. The testing window for the Praxis II is two hours.

You can use this chapter to prepare for the Praxis II. Video presentations are just part of each lesson; you also can read transcripts, some of which include links to other resources for further learning opportunities, and take short, multiple-choice quizzes that are designed to mimic the Praxis II.

Overview of Animal Reproduction and Development

1. Overview of Animal Reproduction and Development

At this stage in life, you likely know where babies come from. However, did you know that some animals can make clones of themselves and reproduce sexually too? In this lesson, you'll learn more about sexual reproduction and early vertebrate development.

Spermatogenesis: How the Male Reproductive System Produces Sperm

2. Spermatogenesis: How the Male Reproductive System Produces Sperm

In this lesson, you'll learn the series of steps necessary to produce a fully functional sperm cell. You'll also look at the structure of a sperm cell and see how it's equipped to venture forth into new territory.

Oogenesis: How the Female Reproductive System Produces Eggs

3. Oogenesis: How the Female Reproductive System Produces Eggs

Did you know that a human female already has all of the oocytes that she will make in her entire life before she is even born? In this lesson, you'll learn how the human body produces an ovum through the process of oogenesis. You'll also learn how polar bodies help to ensure that female gametes are of high quality even though they are not produced in high quantities.

Early Embryonic Development: The Morula and Blastula

4. Early Embryonic Development: The Morula and Blastula

This lesson on the early stages of mammalian development covers the processes following fertilization, such as cleavage, the morula formation and blastula formation. Watch to learn what the inner cell mass, trophoblast cells and blastocyst are, as well as their functions within embryonic development.

Embryo Implantation and Placenta Formation

5. Embryo Implantation and Placenta Formation

This lesson will cover the journey the mammalian embryo first makes after it has been fertilized. Learn how maternal blood moves through the embryo, and how the placenta is formed.

The Placenta and the Fetus: Structure and Function

6. The Placenta and the Fetus: Structure and Function

Have you ever wondered how a baby eats before it's born or if babies go to the bathroom while still inside their mother? In this lesson, you will learn about the placenta and how it works to ensure a fetus stays well-nourished and healthy before birth.

Amniotic Fluid, The Amnion, and the Yolk Sac

7. Amniotic Fluid, The Amnion, and the Yolk Sac

From a chick developing inside an egg to a human baby growing in its mother's womb, all developing vertebrates rely on a support system to protect them, feed them, supply them with oxygen, remove wastes, and do much, much more to ensure that the embryo grows and develops into a fully functional organism. In this lesson, you'll learn about the different parts of that support system and some of the things that they do.

Gastrulation and the 3 Germ Layers (Ectoderm, Endoderm & Mesoderm)

8. Gastrulation and the 3 Germ Layers (Ectoderm, Endoderm & Mesoderm)

Gastrulation is a key process in embryonic development - it's how a simple ball of cells begins to grow into a fully functioning being! Watch this lesson to learn about a key process in the development of almost all multicellular organisms.

Principles of Growth and Development

9. Principles of Growth and Development

Is there a pattern to how human growth and development takes place? This lesson will examine some universal principles of growth and development in order to help you find the answer to this question.

Innate Behavior: Reflexes, Kineses and Taxes

10. Innate Behavior: Reflexes, Kineses and Taxes

When there is a loud sound, you quickly jump without thinking. This is because this reflex is an innate, or inherited, behavior. In this lesson, we will look at reflexes as well as several other types of innate behaviors.

Learned Behavior: Imprinting, Habituation and Conditioning

11. Learned Behavior: Imprinting, Habituation and Conditioning

Ever wonder why it is easier to train your dog when you give him a treat every time he does something correct? In this lesson we will take a look at conditioning as well as several other forms of learned behavior.
