Type of transport in which very large molecules cross the cell membrane.

Process of maintaining a stable environment inside a cell or an entire organism.

Substances cross the cell membrane without the cell providing energy.

The diffusion of water molecules across a membrane.

Type of vesicle transport that moves a substance out of the cell. A vesicle containing the substance moves through the cytoplasm to the cell membrane. Then, the vesicle membrane fuses with the cell membrane, and the substance is released outside the

A substance moves against the concentration gradient (uses energy from cells).

A substance moves through a membrane from an area of high concentration to an area of low concentration.

Type of vesicle transport that moves a substance into the cell. The plasma membrane completely covers the substance, a vesicle pinches off from the membrane, and the vesicle carries the substance into the cell.
