Osmosis
The passage of water from a region of higher water potential to a region of lower water potential through partially permeable membrane
Active transport
The movement of molecules or ions into or out of a cell from a region of lower concentration to a region of higher concentration using ATP and carrier proteins
Sodium potassium pump
j
Co-transport
The transport of one substance coupled with the transport of another substance across a plasma membrane in the same direction through the same protein carrier
