Ch 1: Cell Theory and Living Organisms

About This Chapter

The Cell Theory and Living Organisms chapter of this Cell Biology Study Guide course is the simplest way to master cell theory. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure you learn the essentials of cell theory and living organisms.

Who's It For:

Anyone who needs help learning or mastering cell theory material will benefit from the lessons in this chapter. There is no faster or easier way to learn cell theory. Among those who would benefit are:

  • Students who have fallen behind in understanding cell theory and living organisms
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning biology (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about cell theory and living organisms
  • Students who struggle to understand their teachers
  • Students who attend schools without extra biology learning resources

How It Works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Cell Theory and Living Organisms chapter exam.

Why It Works:

  • Study Efficiently: Skip what you know, review what you don't.

Test your knowledge with a 30-question chapter practice test
What are Cells? - Overview

1. What are Cells? - Overview

All living organisms are made up of cells, but do you know what a cell is? In this lesson, you can learn about the three main structures that all cells contain and about the two major types of cells.

What is Cell Theory? - Definition & Parts

2. What is Cell Theory? - Definition & Parts

Cell theory is a fundamental theory in biology that makes generalizations about cells. This lesson will help you understand the three main principles of cell theory.

The Defining Characteristics of Living Organisms

3. 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.

Organism: Definition & Explanation

4. Organism: Definition & Explanation

An organism is any living thing. There are millions of organisms, so how do scientists organize them all? Learn more about the diversity of life on Earth and how scientists classify them, then take a quiz to test your knowledge!

Unicellular Organisms: Definition & Examples

5. Unicellular Organisms: Definition & Examples

Life takes a great variety of forms. This world is home to many simple organisms that live in a variety of environments. In this lesson, we will examine unicellular organisms to gain a better understanding of them.

Multicellular Organism: Examples & Definition

6. Multicellular Organism: Examples & Definition

Most organisms consist of only one cell and are invisible to the naked eye. Others, such as the rabbit, the bread mold and the pine tree, are made of many cells. Learn how to classify the multi-cellular organisms that inhabit our world.

Multicellular Organisms, Tissues and Epithelium

7. 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.

Taxonomy: Classification and Naming of Living Things

8. 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.

Living Systems Requirement for Free Energy and Matter

9. 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.
