1. Discovering Cells

2.1. Animal Cell
The cell is the basic building block of all living organisms. It is the smallest unit of an organism that can carry out the functions of life.
2.2. Robert Hooke
Robert Hooke was one of the first people to observe cells using his own compound microscope in 1663.
2.3. Cork Cells
To Hooke, the very thin slice of cork under the microscope appeared to be made up of little empty boxes, which he named cells.

2. Pause and Interact

3.1. Animal Cell
Animal cells contain many organelles, which are structures that carry out specific functions. Roll over different parts of this cell. Click on highlighted areas to activate a popup box that identifies the structure. The down arrow reveals additional information and the sound button plays the audio narration. Close the pop-up box by clicking the X. You can also use the onscreen forward and back arrows to reveal each pop-up information box.
3.2. Drag and Drop Animal Cell
Click on the Terms button. Then click and drag each term to the correct box. Use the reset button to clear the terms and start over. Use the gear button to customize the draggable terms.

4.1. Plant Cell
Plant cells contain many organelles, which are structures that carry out specific functions. Roll over different parts of this cell. Click on highlighted areas to activate a popup box that identifies the structure. The down arrow reveals additional information and the sound button plays the audio narration. Close the pop-up box by clicking the X. You can also use the onscreen forward and back arrows to reveal each pop-up information box.
4.2. Drag and Drop Plant Cell
Click on the Terms button. Then click and drag each term to the correct box. Use the reset button to clear the terms and start over. Use the gear button to customize the draggable terms.

4. Organization of Cells

5.1. One-Celled Organism-Amoeba
A one-celled organism, such as an amoeba, is able to perform all of its life functions by itself.
5.2. Cell Tissues
However in many-celled organisms, cells depend on each other and are organized into tissues that perform a specific job.
5.3. Organs and Organ Systems
These tissues are further organized into organs and organ systems that work together to keep an organism alive.

5. Pause and Interact

6.1. Graphic Organizer
Use the whiteboard tools to complete the Venn diagram about plant and animal cell characteristics.

6. Specialized Cells

7.1. Cell Types
The human body consists of trillions of cells, including some 200 different cell types that vary greatly in size, shape and function.
7.2. Cell Size
Sperm cells are the tiniest human cells, a few micrometers wide (1/12,000th of an inch); whereas the longest cells, the neurons that run from the tip of the big toe to the spinal cord, can be as long as several feet in an average adult!

8. Vocabulary Review

9.1. Vocabulary Matching Review

9. Virtual Investigation

10.1. Comparing Plant and Animal Cells
In this investigation you will use a virtual microscope to view slides of cork cells, onion bulb epidermis cells, privet leaf cells and cheek cells. Using the microscope features, you will explore each slide specimen and observe the structure of each type of cell.
