Which cell has microvilli and cilia

Cilia (also called eyelashes or cilia) form the typical locomotor system of the ciliates, but are also found in other eukaryotes. Cilia are made up of microtubules in the (9 + 2) arrangement and move while consuming ATP. They usually cover the entire cell and, strictly speaking, should be classified as intracellular locomotor apparatus, because although a flagellum protrudes from the cell as an extension, it is enveloped by the cytoplasmic membrane and thus an intracellular structure.

Eukaryotic cilia and flagella have a completely different structure than the bacterial flagellin, which consists of flagellin and has a completely different mechanism of movement. The eukaryotic microvilli, which e.g. occur in the human intestine and are important for the intake of food, or the hair cells in the inner ear (stereocilia, also known as stereovilli) have nothing in common with the cilia.
