FOOD VACUOLE-The numerous non-contractile food vacuole or gastrioles can be seen moving with the streaming endoplasm.They differ in shape and size accourding to the nature of the ingested food particles but mostly they are rounded in form.
ORAL APPARATUS-In paramecium the oral groove leads ventrally and posteriorly as a tubular structures called the vestibule. It leads directly into a narrow passage the buccal cavity. In its turn it opens into a narrow gullet or cytopharynx through a narrow aperture the cytostome.The cytopharynx at its proximal end formsa food vacuole.The buccal cavity at the right is bordered by a row of cilia forming the endoral membrane.These are the ventral peniculus ,dorsal peniculus and quadrulus.These ciliary rows constitute the membranelles.Rows of normal somatic cilia linethe wall of vestibule.
