Cell Transport

A type of transport that moves substances across a cell membrane without the use of energy, typically from an area of higher concentration to an area of lower concentration.

A type of transport that requires energy to move substances against their concentration gradient, from an area of lower concentration to an area of higher concentration.

The movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

The process by which particles spread out from an area of high concentration to an area of low concentration until they are evenly distributed.

A state where the concentration of a substance is equal throughout a space, meaning there is no net movement of particles.

A biological membrane that separates and protects the interior of the cell from the external environment, controlling the movement of substances in and out.

A rigid outer layer found in plant cells that provides structure and support, but is not involved in transport.

A process by which a cell expels materials in vesicles that fuse with the cell membrane, releasing their contents outside the cell.

A process by which a cell takes in materials by engulfing them in a vesicle formed from the cell membrane.

The cell loses water through osmosis, causing it to shrivel and the cell membrane to pull away from the cell wall.
