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

Sexual reproduction in animals involves many different steps, beginning with gametogenesis and ending with the formation of three primary germ layers. Discover how those initial steps happen, and explore different definitions of the parts of animal reproduction and development.

Spermatogenesis: How the Male Reproductive System Produces Sperm

2. Spermatogenesis: How the Male Reproductive System Produces Sperm

Spermatogenesis is a process that takes place in the seminiferous tubules where sperm, or male gametes, are formed. Discover other processes and concepts about the production of sperm in the male reproductive system.

Oogenesis: How the Female Reproductive System Produces Eggs

3. Oogenesis: How the Female Reproductive System Produces Eggs

Oogenesis is a process that takes place in the ovaries where female gametes or ova are formed. Learn more about oogenesis and other processes in the female reproductive system's production of eggs, such as meiosis, ovulation, and fertilization.

Early Embryonic Development: The Morula and Blastula

4. Early Embryonic Development: The Morula and Blastula

Following fertilization, the early stages of mammalian development--including cleavage, morula formation and blastula formation--are unique to mammalian embryos. Learn about key processes in each stage of development and how they differ from those in non-mammalian development.

Embryo Implantation and Placenta Formation

5. Embryo Implantation and Placenta Formation

All mammals begin as fertilized embryos. Learn what happens to a mammalian embryo when it is fertilized, understand how implantation occurs, and explore how the placenta forms.

The Placenta and the Fetus: Structure and Function

6. The Placenta and the Fetus: Structure and Function

Babies must eat but also discharge wastes into the mother's blood, for which the placenta can be considered the interface. Explore the structure and function of the placenta and how it facilitates the transfer of nutrients and waste products between mother and baby.

Amniotic Fluid, The Amnion, and the Yolk Sac

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

Living organisms need a support system as they grow from an embryo into a newborn. Learn how amniotic fluid, the amnion, yolk sac, chorion, and allantois function in placental mammals and egg-laying vertebrates to nourish and protect the unborn as they develop.

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

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

Gastrulation is a process that creates three different germ layers in an early embryo called ectoderm, endoderm, and mesoderm. Learn what this process is and discover how it occurs in the gastrulation of frogs and mammals.

Principles of Growth and Development

9. Principles of Growth and Development

The principles of growth and development describe how the process of growth takes place. In this lesson, discover the three universal principles: cephalocaudal, proximodistal, and orthogenetic along with how development occurs.

Innate Behavior: Reflexes, Kineses and Taxes

10. Innate Behavior: Reflexes, Kineses and Taxes

Innate behaviors are inherited and humans and other living organisms usually engage in them without thinking. Learn about innate behaviors, including reflexes, kineses, and taxes, to better understand the relationship between stimulus and innate behavior.

Learned Behavior: Imprinting, Habituation and Conditioning

11. Learned Behavior: Imprinting, Habituation and Conditioning

Learned behaviors are those that are not innate, and are formed throughout our lifetime. Take a look at the different kinds of learned behavior: conditioning, habituation, insight, and imprinting.
