WebIn ciliates like Paramecium, the feeding apparatus is well developed with a definite cytostome. The cytostome is usually present at the base of the oral groove leading into the cytopharynx. The feeding apparatus is provided with some specialised cilia. The beating of the cilia of cytopharynx creates a whirl pool of water current. WebProtozoa ingest their food in two ways.

WebIn amoeboid cells, food particles are engulfed only after receptors on the phagocytic cell’s membrane bind to ligands on a particle’s surface. Ciliates also feed via phagocytosis but, instead of enveloping particles, some ciliates take them up through a complex, permanent, funnel-shaped, feeding apparatus. It is unclear whether receptor ... photo of mumWebThe cilia in the oral groove create a current of water which wafts the food organisms up to the cytostome where they are ingested in a food vacuole. This food vacuole then follows a specific route through the cytoplasm. On its travels, enzymes are secreted into the vacuole and the food is digested. photo of muhammad prophet
