The process of movement of a substance (solid, liquid or gas) from the region of higher concentration to the region of lower concentration so as to spread uniformly is called diffusion.

Selectively permeable membrane is the one which allows entry of certain substances, exit of some substances but prevents the passage of other substances, through it.

An instrument that uses a beam of electrons to visualise cellular structures and thereby examine cellular architecture; the resolution is much greater than that of light microscope, allowing detailed ultra-structural examination.

M.J. Schleiden and T.Schwann proposed the cell theory. Rudolf Virchow modified the cell theory and stated that every cell arises from pre-existing cell.

What is exosmosis?
Exosmosis is the osmotic exit of water from a cell or system due to presence of hypertonic solution on the outside.

See lessWhat is the main function of plasma membrane?
Plasma membrane defines the boundary of the cell and regulates the flow of materials into and out of the cell.

See lessWhat would happen if plasma membrane ruptures?
Ruptured plasma membrane generally heals within no time but if rupturing does not heal, the cell contents will spill over and the cell is killed.
