What are cilia and what they do?
cilia are very small hair like organelles in the respiratory tract that are use to move excess mucus and foreign substances away from the lungs and toward the nasal and oral cavities to be expelled by the body.
What is cilium?
The word is Latin for eyelash. It refers to the hair-like projections on the surface of cells that are used for movement and other functions. The cells that line the cochlea in the inner ear have cilia that transmit a signal to the brain when they are bent by sound waves.
What are cilia and flagella made up of?
Cilia and flagella are made up of microtubules, specifically arranged in a 9+2 pattern. They consist of nine doublets of microtubules surrounding a central pair of microtubules. The movement of cilia and flagella is generated by the sliding of these microtubules past each other.
What is the flagella and cilia?
Cilia and flagella are both hair-like structures that extend from the surface of the cell, where they assist in movement.Cilia are short and more numerous than the longer flagella. They both have a membrane on their outer surface and have an internal structure of nine pairs of microtubules around two central tubules.Sources:Postlethwait, John H., and Janet L. Hopson.

Function of cilia in homeostasis?
Cilia help in maintaining homeostasis by clearing debris, mucus, and pathogens from the respiratory tract. They also play a role in moving fluid and substances along the surface of cells in various organs, contributing to proper function and balance within the body.
Are cilia are extensions of animal cells that move rapidly?
It is true that cilia are extensions of animal cells and that they move rapidly. They are found in several locations in the human body, including the lungs.
Do animal and plant cells both have cilia?
no only animal and protists have cilia
Do plant cells have cilia?
No they do not, they don't have flagellum either.
Is cilia found in both plant and animal cells?
Most plant cells have neither flagellum nor cilium but in some cases there are exceptions. For example, the cycads have some cells with cilia and flagella. In particular, sperm cells have a flagella.
What cell parts do animal cells have that plants do not have?
Animal cells have a lysosomes that are not present and cilia that are rarely seen in plant cells. The lysosomes are the recycling and disposal site in the animal cell. The cilia help the cell move.
Cells lining the trachea have whiplike mortile extensions on their free surfaces What are their extensions what is their source and what is their function?
The whiplike motile extensions are called cilia. They are sourced from the basal body of the cell. The function of cilia in the trachea is to move mucus and trapped particles upward and out of the airway, helping to clear the respiratory tract.
What type of cell is the cilia a plant cell or animal cell?
it is in a plant cell
Is cilia found in animal and plant cells?
yes, but rarely in plant cells. cycada are the most notable exception
Is cilia on both plant and animal cells?
yes
Do animal cells have cilia or flagellum?
yes but only some animal cells like amoeba and like
What are the long cellular extensions that propel cells?
The long cellular extensions that propel cells are called flagella and cilia. They are composed of microtubules and are used by cells for movement and sensory functions. Flagella are typically longer and found singly or in small numbers, while cilia are shorter and found in large numbers on the cell surface.
What are the characteristic of cilia?
They are whiplike, motile cellular extensions that occur in large numbers on the exposed surfaces of certain cells
