How is food transported to food vacuole of paramecium?
By movement of cilia
By pseudopodia
Food vacuole directly captures the food
By contractile vacuole
By movement of cilia
Paramecium uses cilia to sweep food particles along with some water into an oral groove (a groove present on the surface of paramecium). At the end of the oral groove, a food vacuole gets created. This food vacuole further travels throughout the cytoplasm and during this journey, the food inside the vacuole gets digested and absorbed.
