It has two nuclei, one large macronucleus that runs the cell and a micronucleus that is used in a process called conjugation. 00:00 00:00 An unknown error has occurred Webb11 apr. 2024 · Apart from paramecium reproduction, its feeding mechanism is equally essential and elaborate. Paramecium consumes several kinds of food, including unicellular plants, bacteria, tiny insects, and plants. It intakes food through cilia. Cytosome lies at the bottom of the buccal cavity, and food enters the body through it.

The ciliate belongs to an archaic group that used to be called archezoa but this term is no longer in fashion. [11] It has four weak flagella, which serve as a rudder. [12] [11]
WebbMany of the protist species classified into the supergroup Excavata are asymmetrical, single-celled organisms with a feeding groove “excavated” from one side. This supergroup includes heterotrophic predators, photosynthetic species, and parasites. Its subgroups are the diplomonads, parabasalids, and euglenozoans.
