This seven-page Biology course handout gives a detailed explanation, accompanied by many illustrations, of the various processes by which substances travel across the membranes of cells.
University of Hamburg
University of Hamburg: Membranes: Diffusion, Permeability, Osmosis, Turgor, Active and Passive Transport and Transport
This cellular biology page presents extensive detail on the chemical nature of the cell membrane. Using the Chime plug-in, students can manipulate and study models of the membrane.
Georgia Department of Education
Ga Virtual Learning: Anatomy and Physiology: Cells
In this module, students discover how each cell is organized to complete the function of producing and transporting proteins, and how cells relate to homeostasis of the body.

Teach Engineering: Active and Passive Transport: Red Rover Send Particles Over
Students compare and contrast passive and active transport by playing a game to model this phenomenon. Movement through cell membranes is also modeled, as well as the structure and movement typical of the fluid mosaic model of the cell...
