What name is given to the process by which water crosses a selectively permeable membrane?
Osmosis is the process in which the movement of water occurs across a selectively permeable membrane.
Diffusion is merely the movement of a substance from an area of its higher concentration to an area of lower concentration.
Pinocytosis is a special type of endocytosis in which small particles suspended in ECF are taken into the cell through the invagination of the cell membrane.
Phagocytosis is when certain cells called phagocytes(neutrophils, macrophages) ingest/engulf other cells or particles.
In passive transport, the movement of substances occurs across a cell membrane without the need for energy.
The answer is osmosis.
