a cell transports things across the cell membrane from areas of high concentration to ares of low concentration
active transport
Passive transport is a non-energy requiring process that moves materials across a cell membrane with the concentration gradient. This process includes simple diffusion, facilitated diffusion, and osmosis.
The cell membrane is the structure that regulates the transport of molecules in and out of the cell. It is selectively permeable, allowing certain substances to pass through while restricting others. Transport proteins embedded in the membrane help facilitate the movement of specific molecules across the membrane.
Osmosis transports water molecules across a partially permeable membrane, such as a cell membrane. It does not transport other types of materials, like ions or larger molecules.
It's called passive transport for a cell's membrane. (I checked with my science teacher)

Protein.
A bilayer of phospholipids regulates cell traffic. There are five methods of transport across the membrane; diffusion, facilitated diffusion, active transport, co transport and endocytosis/exocytosis.
Protein channels and transporters help transport specific materials across the cell membrane. These proteins create passageways that allow ions, sugars, and other molecules to move in and out of the cell.
Active Transport of Cellular materials.
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
No, passive transport does not require ATP for the movement of molecules across the cell membrane.
