A thorough investigation of cell transport is provided when completing the assignment. The first half requires biology class members to answer questions about diffusion and osmosis with the aid of diagrams. Then they fashion an...

Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...

From the scientific method to the function of a cell, the eBook has it all. A useful resource provides a free biology textbook with a focus on context. The text begins with an overview of the process of scientific inquiry and biology...

Help young biologists piece together an understanding of cell structure with a comprehensive review worksheet. Tasking students with describing the function of the organelles found in cells and their relationship with one another,...

Young scientists demonstrate their understanding of cell transport on this comprehensive instructional activity. Focusing on cellular structure and the different processes that allow materials to move into, out of, and...

Take your biology class on an exploration of the inner workings of cells with this multimedia presentation. Looking closely at the structure of cell membranes and the processes of osmosis and diffusion, this resource explains for...

You may find this presentation helpful in setting up the classic experiment where potato wedges are used for observing the effects of osmosis. You can view the experimental setup in the text and a lab sheet in the pictures, but you will...

As an anticipatory set, biologists listen to the story of Ruth Patrick, a scientist who used algae to detect water quality. They observe a demonstration of osmosis and diffusion. In their lab groups, they place Elodea stalks in...

Students set up a cell membrane with the material provided by their teacher and then arrange beads properly to show how the sodium and potassium ions are arranged. They then make a model representing the axon of a neuron.

This technical site provides an in depth look at membrane transport by clearly explaining the processes of diffusion and osmosis. Links are provided to clarify terminology.

[Free Registration/Login may be required to access all resource tools.] Describes exocytosis and endocytosis.

Explains the process of facilitated diffusion which allows selective movement of materials across the cellular membrane.

Cell transport can be active or passive. The two forms are described here and their differences highlighted.
