WebFlagellates employ their flagella for both swimming and acquiring food. Sessile or colony-forming members of the collared flagellates use their flagella to create a water current to draw small food particles, such as water-borne bacteria. WebCiliates also feed via phagocytosis, but instead of enveloping particles the way amoebae do, ciliates take up particles through a complex, permanent, funnel-shaped feeding …

How are ciliates harmful? - Studybuff

WebThe 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. http://biology-resources.com/paramecium-01.html north of barrie
