colloidal dispersion

A mixture containing colloid particles that fail to settle out and are held in suspension. They are common in animal and plant tissues; the protoplasm of cells is an example. Particles of colloidal dispersions are too large to pass through cell membranes. Such dispersions usually appear cloudy.
