The Defining Characteristics of Living Organisms

1. 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.

What is a Life Cycle? - Definition, Stages & Examples

2. What is a Life Cycle? - Definition, Stages & Examples

In this lesson, you'll learn the definition of 'life cycle' and find out about the three basic stages of a life cycle. You'll also explore examples of different life cycles.

Interaction of Major Systems & Processes in Plants

3. Interaction of Major Systems & Processes in Plants

In this lesson, we'll be exploring the relationship between major systems and processes in plants. We'll look at the ascending cellular structure of plants from organelles to organism and how these relate to molecular functions.

Interaction of Major Systems & Processes in Animals

4. Interaction of Major Systems & Processes in Animals

In this lesson, you'll learn about interactions at all levels of animals: organelles, cells, tissues, organs, organ systems, and organisms themselves. You'll also have a better understanding of the complexity of the organization of living things.

What are the Human Body Systems?

5. What are the Human Body Systems?

There are ten organ systems in your body that each have different functions, and they all must work together to keep you alive and healthy. In this lesson, you'll learn about each of these body systems, both what they do and which organs they contain.

Genetics: Heredity, Traits & Chromosomes

6. Genetics: Heredity, Traits & Chromosomes

We view manipulation of genes in our crops and livestock as a recent development. Yet, man has been manipulating the genetic makeup of his food for thousands of years through cultivation and breeding. This lesson will begin to help you understand how genetics works.

Asexual vs. Sexual Reproduction: Comparison & Characteristics

7. 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 Habitat? - Definition & Explanation

8. What Is Habitat? - Definition & Explanation

Most people would agree that there's no place like home. In this lesson, we'll examine the biological version of a home, known as a habitat. It's important for us to know what makes up our habitat as well as other organisms' habitats.

Factors that Affect Animal Population Size

9. Factors that Affect Animal Population Size

In this lesson, you will learn about the many factors that may influence animal population size, such as nutrition, competition, and even things like parasitism.

Renewable & Non-Renewable Resources: Definition & Differences

10. Renewable & Non-Renewable Resources: Definition & Differences

We use a variety of Earth's resources, but not all of them will be around forever. This lesson explains the difference between resources that can be regenerated for our use and those that are gone after they are used once.

Land Conservation: Preserving and Restoring Ecosystems

11. Land Conservation: Preserving and Restoring Ecosystems

Humans have degraded a large portion of natural land. The field of land conservation has become popular as a way to fix this problem. Land conservation attempts to combat land degradation through preservation, restoration, remediation, and mitigation.
