Ch 37: Praxis General Science: Hierarchical Classification Scheme

About This Chapter

Review these lessons to learn more about scientific names and the hierarchical classification scheme. A careful study of this chapter will help prepare you for any related questions on the Praxis General Science test.

Praxis General Science: Hierarchical Classification Scheme - Chapter Summary

This chapter serves to ready you for the Praxis General Science exam by looking at the hierarchical classification scheme, or the classification of plants and animals. Information reviewed in these lessons includes:

  • Living things, free energy and matter
  • Qualities of a living organism
  • Explanation of taxonomy
  • Growth, dynamic homeostasis, reproduction, and their environmental requirements
  • Impact of feedback systems on dynamic homeostasis, growth, and reproduction

Each brief video lesson is accompanied by a full transcript, so you have the ability to progress through this chapter at your own pace. Key vocabulary words will be highlighted, and they can aid you in your studies for the Praxis General Science exam. Be sure to take the short practice quiz at the end of each lesson to both ascertain how well you comprehend the content and to practice answering questions in a multiple-choice format like you'll find on the exam.

Praxis General Science: Hierarchical Classification Scheme Objectives

In order to gain your certification to teach science courses, you should take this exam, which is geared towards assessing your knowledge of this subject. The Praxis General Science exam consists of 135 multiple-choice questions with content spanning five categories. Approximately 27 questions (or 20%) are focused on life science. One of the topics tested within the life science category is the hierarchical classification scheme, the main subject of this chapter.

Through reviewing the lessons of this chapter in a focused manner, and by testing your knowledge using the practice quizzes, you may use this chapter as a valuable study tool. A complete understanding of the information provided within this chapter will give you the knowledge necessary to confidently answer any pertinent questions on the exam.

Living Systems Requirement for Free Energy and Matter

1. Living Systems Requirement for Free Energy and Matter

Free energy and matter are required by all living things in order to grow, reproduce, and maintain biological processes. Additionally, free energy and matter must also be recycled through the environment in order to remove dead material and allow for new growth.

The Defining Characteristics of Living Organisms

2. The Defining Characteristics of Living Organisms

A house is not a living thing, but the people, animals, and plants living inside it are. So how do we define 'life'? Learn about seven characteristics that all living organisms have in common, no matter how different they may look on the outside.

Taxonomy: Classification and Naming of Living Things

3. Taxonomy: Classification and Naming of Living Things

The name you give to a living thing may be completely different than the name someone else uses. In science, we use a common naming system for all living things to avoid confusion. This lesson will explore the basics of our classification system.

The Environmental Requirements for Growth, Reproduction & Dynamic Homeostasis

4. The Environmental Requirements for Growth, Reproduction & Dynamic Homeostasis

Cells need to maintain internal environments that are different from their external environments in order to grow and reproduce. In this video lesson, you will understand some ways that cells can control their internal conditions to ensure proper biological functioning.

Using Feedback Systems to Regulate Growth, Reproduction & Dynamic Homeostasis

5. Using Feedback Systems to Regulate Growth, Reproduction & Dynamic Homeostasis

In order to maintain specific internal conditions, organisms use feedback mechanisms. Feedback is essential to the regulation of internal environments, which allows for proper biological functioning.
