About This Chapter
How It Works:
- Identify the lessons in the Classification of Living Things chapter with which you need help.
- Find the corresponding video lessons with this companion course chapter.
- Watch fun videos that cover the taxonomy topics you need to learn or review.

1. 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.
2. Carolus Linnaeus: Classification, Taxonomy & Contributions to Biology
There are millions of species on Earth. How can we name and organize all of them without getting confused? We use a system developed in the 1700s by Carolus Linnaeus. Learn more about him and his contributions in this lesson.
3. What is Bacteria? - Definition, Characteristics & Examples
This lesson will introduce the Bacteria, a large and diverse group of microorganisms. We will examine several key characteristics, as well as a few commonly known examples of bacterial species.
4. Archaea: Definition, Characteristics & Examples
There is an entire domain of life that is made up of single-celled organisms without nuclei. We're not referring to the Bacteria domain, however. In this lesson, we will examine the main characteristics of the least commonly known domain, the Archaea.
5. Eukarya: Definition, Characteristics & Examples
What makes us so complex? How are we any different from simple single-celled bacteria? It's because we're further up the evolutionary chain; we're examples of eukaryotes. In this lesson, we'll define Eukarya and eukaryotes and explore their characteristics.
6. Kingdom Protista: Definition, Characteristics & Examples
Learn about the requirements to enter Kingdom Protista, one of the five kingdoms of life. Discover and read about the organisms that can be found there.
7. Kingdom Plantae: Facts, Characteristics & Examples
Chances are, you can thank a plant for your clothes, your food, and even your house. This lesson will explore the kingdom plantae including characteristics plants share as well as some facts and examples of organisms within this kingdom.
8. Kingdom Fungi: Definition, Characteristics, & Examples
The kingdom Fungi includes a diverse group of organisms that are neither plant nor animal. They absorb nutrition from other organisms while playing the important role of ecological decomposers. Learn more about this group and take a short quiz at the end.
9. Animalia Kingdom: Definition, Characteristics & Facts
With over one million different species, the Animalia Kingdom is considered the largest kingdom. Its organisms also inhabit the most diverse habitats on Earth. This lesson will examine what characteristics animals possess and then will list some awesome animal facts.
10. Cladograms and Phylogenetic Trees: Evolution Classifications
Family trees help show how people are related to each other. Similarly, scientists use cladograms and phylogenetic trees to study the relationships between organisms.
11. The Dichotomous Key: A Classifying Tool
Sometimes, the best way to identify an object is to take a step-by-step approach. Dichotomous keys are perfect for this, helping us classify unknown objects through a series of questions and answers that lead us down the correct path.
