Now, let us sit back, review the workings of the cilium, and consider what it implies. Cilia are composed of at least a half dozen proteins: alpha-tubulin, beta-tubulin, dynein, nexin, spoke protein, and a central bridge protein. These combine to perform one task, ciliary motion, and all of these proteins must be present for the cilium to function. If the tubulins are absent, then there are no filaments to slide; if the dynein is missing, then the cilium remains rigid and motionless; if nexin or the other connecting proteins are missing, then the axoneme falls apart when the filaments slide. What we see in the cilium, then, is not just profound complexity, but also irreducible complexity on the molecular scale. Recall that by "irreducible complexity" we mean an apparatus that requires several distinct components for the whole to work. A mousetrap must have a base, hammer, spring, catch, and holding bar, all working together, in order to function. Similarly, the cilium, as it is constituted, must have the sliding filaments, connecting proteins, and motor proteins for function to occur. In the absence of any one of those components, the apparatus is useless
What else can I help you with?
Which structures are not found in prokaryotes cells?
nuclei
What is an axoneme?
An axoneme is the core structure of a cilium or flagellum, made up of microtubules organized in a specific pattern. It provides support and determines the movement of the cilium or flagellum. The axoneme is essential for motility in many organisms, including single-celled organisms and cells within multicellular organisms.
How many primary cilia stick out of cells that have them?
Most cells that have primary cilia typically have only one primary cilium per cell. This primary cilium acts as a sensory organelle protruding from the cell's surface, playing a crucial role in cellular processes such as signal transduction and cell signaling.
What is a long hair like extension that is used to move cells?
A cilium is a long hair-like extension found on the surface of some cells. It can move in a whip-like motion to help cells move or transport materials.
What does the basal body do?
The basal body is an organelle that serves as the base of a eukaryotic flagellum or cilium. It anchors these structures to the cell and is involved in their formation and function, aiding in cellular movement and sensory perception.
What is the singular form of the word cilia?
Singular form for cilia is cilium. Cilium is an organelle found in eukaryotic cells. In Latin cilium means eyelash.
Which structures are not found in prokaryotes cells?
nuclei
What organell do plant cells have that animal cells do not?
Centrioles, acrosome (only in sperm), cilium is rare in plants.
What is hairlike projections on the outside of the cells?
Cilia (singular cilium). Unless you mean the outside of epidermal leaf cells, in which case they are trichomes.
When was Spodoptera cilium created?
Spodoptera cilium was created in 1852.

Cilia is the plural form of the Latin for what word?
Singular form of "cilia" is cilium. The meaning of the word "cilia" is hairlike organelles that line the surface of certain cells, and it also means eyelids.
What do cilium's do?
cilium helps in swimming locomotion. they are seen in protozoans like vorticella, paramecium
What is a long hair like extension that is used to move cells?
A cilium is a long hair-like extension found on the surface of some cells. It can move in a whip-like motion to help cells move or transport materials.
What are two cell appendages that help the cells move?
flagella or cilia, but they can also move by cytoplasmic streaming
What word can I make with the letters l you i m i c?
Those letters spell CILIUM, a word for the small, hairlike structures on the surface of some cells.
