Eukaryotic and Prokaryotic Cells: Similarities and Differences

1. 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.

Organelles: Internal Components of a Cell

2. Organelles: Internal Components of a Cell

The organelles of a cell are much like the organs of your body. In fact, the word organelle means little organ. Learn about important organelles of a human cell, such as the nucleus, endoplasmic reticulum, mitochondria, lysosomes and Golgi bodies.

The Difference Between Plant and Animal Cells

3. The Difference Between Plant and Animal Cells

While both plant and animal cells are eukaryotic and share many similarities, they also differ in several ways. Learn about the key differences between these two cell types in this lesson.

Passive & Active Transport in Cells

4. Passive & Active Transport in Cells

In order for your cells to survive, nutrients and other substances must be allowed to move in and out across the cell membrane. Sometimes this requires energy (active transport), and sometimes it does not (passive transport).

Living Organisms: Organization, Functions & Structure

5. Living Organisms: Organization, Functions & Structure

In this lesson, you'll learn about living organisms and how they're structured and organized. You'll also discover how the larger functions of organisms are spread into smaller parts. Then, take a quiz to test what you've learned.

Specialized Cells: Types & Functions

6. Specialized Cells: Types & Functions

Our bodies are made up of cells, but they are not all the same. Cells are specialized according to their functions. In this lesson, we'll learn about cell specialization and see examples of specialized cells.
