NEET BIOLOGY

Detailed explanation-1: -Paramecium is the only genus in the family Parameciidae, which resides within the phylum Ciliophora. Paramecia are completely covered with cilia (fine hairlike filaments) that beat rhythmically to propel them and to direct bacteria and other food particles into their mouths.

Detailed explanation-2: -Paramecium has around 4, 000 motile cilia on its surface arranged in longitudinal rows, beating in waves to ensure movement and feeding. As with cilia in other model organisms, direction and speed of Paramecium ciliary beating is under bioelectric control of ciliary ion channels.

Detailed explanation-3: -Paramecium is unicellular, free-living protozoa. It is completely covered with tiny, hair-like projections called cilia which beat rhythmically to propel them. They arise by penetrating the pellicle from basal bodies located within the ectoplasm of the cell.

Detailed explanation-4: -Also, the cilia are made of the plasma membrane with longitudinal fibrils. These longitudinal fibrils are of two kinds namely the inner fibrils and the outer fibrils.

Detailed explanation-5: -Paramecium are single-celled organisms that belong to the Ciliophora phylum. Members of this group are characterized by having cilia, or little hair-like structures covering their surface.
