About This Chapter
OAE - Integrated Science: Organism Classification & Processes - Chapter Summary
This chapter explores the process of organizing organisms into different classifications. It explores the basic elements of life, provides a broad overview of the types of organisms in our world, and discusses the theory of evolution. These lessons also help you review:
- How organisms transform energy
- Types of reproduction
- Evolution of animals, plants, fungi and protists
- Viruses and disease
- Feedback systems
Our instructors make your review process interesting and engaging through informative lessons filled with entertaining animations. We also have quizzes at the end of each lesson to help you with your comprehension. The quizzes use questions in a similar format to the ones you may encounter on your upcoming exam.
OAE - Integrated Science: Organism Classification & Processes - Chapter Objectives
This chapter is part of the life science domain of the OAE Integrated Science exam. This computer-based exam also tests you on three other domains: physical science, earth science, and the nature of science. The life science domain comprises about 25% of the 150 multiple choice questions. You will have three hours to answer all 150 questions.
1. The Foundational Elements of Life
Living things are complex products of their environments. They are made of a number of different natural elements, many of which are essential to survival. Because of this, they are considered foundational elements and they support life on Earth as we know it.
2. Energy and Life: The Transformation of Energy in Living Organisms
While the sun is an excellent source of energy, not all forms of life can utilize the sun's energy directly. This lesson describes how plants transform the sun's energy into potential energy stored in sugar, how living organisms utilize energy in sugar to perform work, and how the relationship between photosynthesis and cellular respiration is necessary for life.
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.
4. 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.
5. Multicellular Organisms, Tissues and Epithelium
In this lesson on multicellular organisms, you'll take a look at what it actually means to be multicellular and how cells are organized into tissues, organs, and organ systems. This lesson also covers one of the four main tissue types: epithelial tissue.
6. The Evolution of Protists: Importance & Evolutionary History
Some organisms are very familiar. However, there are some that play vital roles in our lives that we don't even think about. We will look at a group of one of these unfamiliar kingdoms - protists.
7. The Evolution of Plants and Fungi: Characteristics & Evolutionary History
In early classification systems, plants and fungi were grouped together. While there are some similarities between these two kingdoms, there are some key differences that we will explore.
8. The Evolution of Animals: Importance & Evolutionary History
The animal kingdom ranges from simple organisms like sponges to complex organisms like humans. We will look at some defining characteristics of animals as well as examples of both invertebrates and vertebrates.
9. 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.
10. 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.
11. What Are Viruses? - Definition, Structure & Function
In this lesson, you'll learn some historical facts about viruses and the material they are composed of. Find out more as we review the capsid, nucleic acids, the viral envelope, viruses, virions, bacteriophages and virology.
12. What is Prion Disease? - Symptoms & Treatment
Learn about prion disease and the symptoms that are associated with the disease. We will also look at the treatments that are used to address prion disease. After this lesson, you can take the short quiz to test your knowledge.
13. What Is Homeostasis? - Definition & Examples
Homeostasis can be defined as a property of an organism or system that helps it maintain its parameters within a normal range of values. It is key to life, and failures in homeostasis can lead to diseases like hypertension and diabetes.
