In other words, a diagram of the membrane (like the one below) is just a snapshot of a dynamic process in which phospholipids and proteins are continually sliding past one another.

The fluid mosaic model of the cell membrane is how scientists describe what the cell membrane looks and functions like, because it is made up of a bunch of different molecules that are distributed across …

An organelle (think of it as a cell’s internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, most organelles are also bound in a double …

All cells have a cell membrane that separates the inside and the outside of the cell, and controls what goes in and comes out. The cell membrane surrounds a cell’s cytoplasm, which is a jelly-like …

Underneath the cell wall lies the plasma membrane. The basic building block of the plasma membrane is the phospholipid, a lipid composed of a glycerol molecule attached a hydrophilic (water-attracting) …

Learn about the structure and function of the cell membrane, nucleus, ribosomes, mitochondria, chloroplasts, and vacuoles.

The plasma membrane Learn Fluid mosaic model of cell membranes Structure of the plasma membrane

Structure and function of the plasma membrane and cytoplasm of cells. Also covers the phospholipid bilayer and microvilli.

Eukaryotic cells have membrane-bound organelles (structures that carry out functions inside cells). This means they have a membrane-bound nucleus which contains the cell’s genetic material. A …
