Overview
The plasma membrane is like a smart security guard of the cell that controls what enters and exits the cell. Just as our body needs food, water, and oxygen while removing waste products, cells also need to transport various materials across their boundaries. This chapter explores the fascinating mec
Key Concepts
The plasma membrane is the outermost
The plasma membrane is the outermost flexible covering of cells that acts as a selective barrier. It allows certain substances to pass through while b
Osmosis is the movement of water
Osmosis is the movement of water molecules from a region of lower solute concentration to higher solute concentration through a selectively permeable
Diffusion is the process by
Diffusion is the process by which substances spread from areas of high concentration to low concentration until evenly distributed. Observable in ever
Solutions can be classified based on
Solutions can be classified based on solute concentration: dilute (less solute), concentrated (more solute), and saturated (maximum solute dissolved).
A membrane that allows solvent (like
A membrane that allows solvent (like water) to pass through but prevents the passage of solutes. The egg membrane experiment demonstrates this propert
