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.

Eukaryotic and Prokaryotic Cells: Similarities and Differences

2. Eukaryotic and Prokaryotic Cells: Similarities and Differences

In this lesson, we discuss the similarities and differences between the eukaryotic cells of your body and prokaryotic cells such as bacteria. Eukaryotes organize different functions within specialized membrane-bound compartments called organelles. These structures do not exist in prokaryotes.

What Are Viruses? - Definition, Structure & Function

3. 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.

Cellular Structure: Function & Definition

4. Cellular Structure: Function & Definition

Living organisms are divided into two major types, prokaryotes and eukaryotes. This lesson describes the structure and functions of these two cell types. When you are through, you can test your understanding with a quiz.

Organelles in Cells: Definition & Functions

5. Organelles in Cells: Definition & Functions

This lesson will focus on the major organelles that are found inside of eukaryotic cells. It will discuss their structures and functions. The differences in organelles found in plant and animal cells will also be covered.

Six Elements Common to Biological Organisms

6. Six Elements Common to Biological Organisms

All living things have six key elements in common. Here, we'll examine those six elements, describe their properties and find out why they're crucial to life.

Major Elements in Biological Molecules: Proteins, Nucleic Acids, Carbohydrates & Lipids

7. Major Elements in Biological Molecules: Proteins, Nucleic Acids, Carbohydrates & Lipids

Bacterial cells have complex macromolecules built from simple molecules. In this lesson, we will look at the major elements in the building blocks of proteins, nucleic acids, carbohydrates, and lipids.

What Is the Purpose of Protein Synthesis?

8. What Is the Purpose of Protein Synthesis?

This lesson will cover the basic steps of protein synthesis. Once we review, we'll look at some key examples of why protein synthesis is important in animals, plants, and bacteria.

What Is the Function of Protein Synthesis?

9. What Is the Function of Protein Synthesis?

This lesson discusses the function of protein synthesis. We'll explore this very important process and some of the many roles it plays in sustaining life. At the end of the lesson, test your knowledge with a quiz.

Types of Cell Division

10. Types of Cell Division

How do cells divide? Do they all divide in the same manner? This lesson answers those questions through an investigation into the three types of cell division: mitosis, meiosis and binary fission.

Multicellular Organisms, Tissues and Epithelium

11. 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.
