Understanding Movement of Molecules across the Cell Membrane
Category
Published on
Abstract
This lesson uses a macro-model to demonstrate the diffusion of molecules across the cell membrane. A deshelled egg serves as the cell model to observe movement in and out of the “cell”. Students will learn that the cell membrane is composed of a complex nano-structured membrane that regulates diffusion and mobility of membrane biomolecules. The purpose is to examine permeability properties of plasma membranes and give students a better understanding of how substances, nano in size move into and out of a cell.
