Title: _________________________________________________________________ (1 pt) Introduction: Cells have an outer covering called the cell membrane . This membrane is selectively permeable; it has tiny pores or holes that allow objects to move across it. The cell membrane controls what moves in and out of the cell. Food and oxygen move into cells across the cell membrane through the process of diffusion . Diffusion is movement of a substance from an area of high concentration to an area of low concentration. Osmosis is a special type of diffusion; it is the diffusion of water across a selectively permeable membrane. Osmosis occurs when water moves from an area where it is more concentrated to an area where it is less concentrated. In this lab, you will examine the process of osmosis using a chicken egg with the shell removed to observe passive transport. The shell-less egg will represent a cell and its selectively permeable membrane. In organisms, the active and passive transport across the cell membrane plays a key role in regulating concentrations of solvents (typically water) and solutes (various minerals and molecules). This regulation is in turn critical for the cellular processes that maintain homeostasis. A demonstration of cellular homeostasis maintained by osmosis (passive transport) can be observed in a chicken egg.
