The parts and functions of the mitochondria are described as well as the many illnesses that can result from mitochondrial dysfunction.

An illustrated overview of the structure and function of the cell and its structures.

Resource takes a look at the structure and function of the organelles mitochondria and chloroplasts. It also examines endosymbiosis, where the organelles probably came from.

This module focuses on cell structure and how the organelles function together to form the smallest unit of life. The cell theory is also discussed along with the basics features of the cell. Site also includes an interactive practice...

[Free Registration/Login may be required to access all resource tools.] For many years, archaea were classified as bacteria. Like the bacteria, archaea lacked a nucleus and membrane-bound organelles and, therefore, were prokaryotic...

[Free Registration/Login may be required to access all resource tools.] Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most protists are single-celled. Other than these features, they...

[Free Registration/Login may be required to access all resource tools.] Even though plants and animals are both eukaryotes, plant cells differ in some ways from animal cells. Plant cells have a large central vacuole, are surrounded by a...

Reiew important information and key points about cell structures.

This tutorial compares prokaryotic and eukaryotic cellular organization and contrasts cells with viruses. Includes a practice quiz to test your knowledge.

A biology class is divided into two groups: one an animal cell, and the other one, a plant cell. They are given a list of cell organelles to research and construct in their 9 M X 9 M model. Students must organize and assign duties,...

Wikipedia offers brief but accurate information on cytoplasm, the matter contained within the plasma membrane of a cell.

Article looks at the structure and function of the different parts of the endomembrane system, how proteins, lipids, and vesicles are transported between these parts, and how this activity keeps the cell running smoothly.

There are three types of protein fibers in the cytoskeleton: microfilaments, intermediate filaments, and microtubules. This resource examines each type of filament, as well as some specialized structures: flagella, cilia, and centrosomes.
