Cellular Transport

A type of cellular transport that requires energy to move substances against their concentration gradient.

The movement of substances across a cell membrane without the use of energy, following the concentration gradient.

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

An organelle that surrounds all cells, controlling what enters and leaves the cell.

A group of cells that work together to perform a specific function.

An organelle that acts as a road system for proteins and lipids within the cell.

The process by which molecules spread from areas of high concentration to areas of low concentration.

A type of passive transport that uses protein channels to help move substances across the cell membrane.

An organelle that modifies, sorts, and packages proteins and lipids for secretion or use within the cell.

A rigid outer layer that provides support and protection to plant cells, not found in animal cells.
