Describes the human stomach in terms of its structural components.

In this lesson, students will investigate plant cells and microscope measurement together by using Elodea plants.

In this activity, students use a virtual biology lab to perform investigations and learn lab procedures using compound and dissecting microscopes to look at a variety of animal and plant cells.

All living things are made of cells. In the human body, these highly efficient units are protected by layer upon layer of defense against icky invaders like the cold virus. This learning module takes a journey into the cell, introducing...

Essay on the history of our knowledge of cells and the development of the cell theory.

These microscope activities provide students with lots to explore. Activities include the characteristics of living things, math in science, cell biology, genetics, physiology, and mitosis.

Multi-activity learning module in which students engage in learning about plant and animal cells through the use of microscopes.

Imagine having a microscopic camera so small that you could travel inside a cell. This interactive site allows you to do just that. Click on any one of eight individual parts of the cell--cell membrane, nucleus, DNA, RNA, ribosome,...

The elephant is a creature of epic proportions- and yet, it owes its enormity to more than 1,000 trillion microscopic cells. And on the epically small end of things, there are likely millions of unicellular species, yet there are very...

Explore the parts of a compound microscope and view cells through this interactive lesson.

[Free Registration/Login may be required to access all resource tools.] A cell is the smallest structural and functional unit of an organism. Learn more about cell biology in this learning module produced by CK-12.

Students use guided scientific observation using a collection of models, visual material, and microscope slides to identify cell organelles. Then they demonstrate their understanding of the parts/characteristics of cells by identifying...

Extensive site for teachers provides some helpful resources that pertain to plant and animal cells. Includes a microscope diagram as well as plant, animal and pond labs. Also contains links to structures and mechanisms, matter and...

The images and videos here allow students to see on a microscopic level what happens when cells are fertilized.

Use this series of images depicting the process of mitosis in the early embryo of the fruit fly, Drosophila melanogaster to make a mitosis flipbook. In this stage of Drosophila development, nuclei divide very rapidly without cell...

Through full-color images and concise information, learn about the origin of cells. Discover some of the notable studies surrounding the history of life on Earth.

Organisms are made of cells. Most organisms are multicellular and have cells that are specialised to do a particular job. Microscopes produce magnified images of cells so we can study them in detail. This lesson focuses on animal cells.

In this lesson students learn about the circulatory system and how it relates to engineering. Then in a hands-on activity they create a model of blood. Students also act out cholesterol in a blocked artery and look at blood cell in a...

This colorful site provides a gallery of blood cell photos. You can observe human white blood cells, human red blood cells, sheep red blood cells, and zebrafish red blood cells. As an added bonus, you can enlarge the red blood cell...

See several specimens of microscopic images of bone cells and tissue.

As we walk through our daily environments, we're surrounded by exotic creatures that are too small to see with the naked eye. We usually imagine these microscopic organisms, or microbes, as asocial cells that float around by themselves....

Get an overview of light microscopes, scanning electron microscopes and transmission electron microscopes. There is also a brief description of sizes for several microscopic objects.

[Free Registration/Login may be required to access all resource tools.] Introduces cells, cell theory, and the levels of organization in organisms.

Discover microscopic images of various eukaryotic cells, both plant and animal.
