Description:

TEKS B 4.  The student knows that cells are the basic structures of all living things with specialized parts that perform specific functions.

 

This tutorial is to introduce cellular structures and functions.  Students will take notes on cellular structures and explore structures, functions, and processes using the iPad apps "iCell" and "Powers of Minus Ten" (POMT).

iPad Activity - iCell

Obtain an iPad from your teacher and launch the app "iCell."  Explore the animal, plant, and bacterial cells, identifying the structures you have learned about and their functions.

iPad Activity - Powers of Minus Ten (POMT)

Obtain an iPad from your teacher and launch the app POMT (Powers of Minus Ten).  Select Single Player if you are working alone or Multi Player if you are working with a group.  You will enter your name(s) and then press the arrow to enter the app.  Your point of view begins on the outside of a hand.  Pinch out to zoom into the skin and then inside the skin to view the cells.  Navigate around to identify the different kinds of cells within the skin.  In this activity, you are to focus on the skin cells rather than the stem cells, cells in various stages of mitosis, or red blood cells.  Locate a skin cell and "tag" it to stabilize the image.  Pinch out to zoom in and identify the various cellular structures. As you identify structures, you will gain points on the meter at the top right of the screen.  Once you have identified all the structures in the cytoplasm, zoom into the nucleus and identify the structures inside the nucleus.

After identifying the structures and functions of all the cell's organelles and structures, enter the Lab, where you may engage in several games to test your knowledge and understanding of the structures and their functions.
