it is suggested that precursor particles 22 mmicro in diameter differentiate at template sites close to membranes bordering cytoplasmic vacuoles and that these particles either pass into the lumen of the vacuole , acquiring in the process a coat and peripheral membrane , or are dispersed in the cytoplasm and extruded through the cellular wall , emerging as viral particles on the surface .
