Paramecium feeding

Paramecium can take in food only at the cytostome. The 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. The digested substances are then absorbed into the cytoplasm.
