Characteristics of Living Things

1. Characteristics of Living Things

Have you ever wondered what makes something alive? Learn more about the characteristics that classify something as living. These shared traits can be observed in all living things in the world around us.

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.

Living Organisms: Basic Needs

3. Living Organisms: Basic Needs

There are many types of living organisms on Earth. But what makes us all the same is our basic needs for survival, which is a shorter list than you might think!

Classification of Vascular, Nonvascular, Monocot & Dicot Plants

4. Classification of Vascular, Nonvascular, Monocot & Dicot Plants

Plants may not seem like the most interesting things around, but they are definitely useful. In this lesson, we will explore the basic classification of plants and the unique characteristics of each group.

What is Plant Physiology? - Definition & Experiments

5. What is Plant Physiology? - Definition & Experiments

Plants are enjoyed by many people - in our homes, on our tables as foods, and in hundreds of products we use every day. In this lesson, we will explore how plant physiology helps us to understand the many functions and behaviors of plants.

The Significance of Physiological Processes in Animals

6. The Significance of Physiological Processes in Animals

Physiology is the study of how living organisms function. Looking at this through an organ-system view, we can see how animals evolved different ways of functioning for their particular habitats.

Stimuli: Definition & Examples

7. Stimuli: Definition & Examples

Stimuli are constantly affecting us and our daily lives. Therefore, it is important to understand how stimuli can cause changes in our environment and how we are able to adapt to them.

Internal & External Stimuli: Definition & Examples

8. Internal & External Stimuli: Definition & Examples

What are internal and external stimuli? Learn how the body uses messages from outside and inside of you to maintain perfect balance and keep you healthy and safe.

Predicting How Organisms Will Respond to External Stimuli

9. Predicting How Organisms Will Respond to External Stimuli

Reacting to stimuli is one of the requirements for something to be considered 'alive'. This lesson will explain what a stimulus is, and how an organism might react to some possible stimuli.

Homeostasis in Plants

10. Homeostasis in Plants

In this lesson, we'll discuss what homeostasis is and how plants achieve homeostasis. We'll also talk about how plants handle heat, water, and nutrients and how they respond to their environment.

Homeostasis in Animals

11. Homeostasis in Animals

What is homeostasis in animals? How does it work? Learn about the various factors that must be kept consistent inside animals and how that happens. When you are through, test your new knowledge with a short quiz!

Homeostasis and Temperature Regulation in Humans

12. Homeostasis and Temperature Regulation in Humans

Do you wonder how your body is able to maintain a consistent temperature? Have you ever questioned why you get goosebumps when you're cold? This lesson will introduce you to homeostasis and answer your questions about body temperature regulation and reactions, like goosebumps.
