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.

Flagella and cilia are both hair-like structures found on cells that are involved in movement. Flagella are typically longer and fewer in number, while cilia are shorter and more numerous. Both structures are used by cells for various functions such as moving fluid or propelling the cell itself.
Cilia (singular: cilium) are tiny organelles (like organs for large creatures, only small and not made of individual cellular components, IE, all part of a single cell) that form on the outer surface of the cell wall and are used by the cell to move around or to manipulate things. This typically occurs in cells that are autonomous, such as single-celled organisms, but can also occur in cells that regulate the immune system of creatures. A cell can have many cilia. They look sort of like 'hair' on the cell.
Flagella (singular: flagellum) are slightly larger, but serve similar functions as cilia. The difference being the size (Larger than cilia, but still part of a single cell), the number (generally very few, and usually only one to a cell), and their ability to manipulate things (they don't. They serve only as motors for the cell). These look like a 'tail' on a cell.
Some single celled organisms have several flagella, however these are functionally the same as cilia, and only distinguished as flagella due to length. This is mostly a eukaryote feature.
Both cilia and flagella have some secondary functions that are more passive, such as acting as sensory probes in detecting heat, chemicals, etc.
Wikipedia, while not infallible, has some very good information on cilia, flagella, and various other physiological and biological structures.
Cilia and flagella are made of microtubules that are bundled together in a particular pattern. Some are in the center and others are around the outside in a circle of bundles.

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.
Is flagella longer and more numerous than cilia?
Flagella are longer and fewer in number compared to cilia. Flagella typically range from 10-200 micrometers in length and there are usually one to a few present per cell. Cilia, on the other hand, are shorter (usually 2-10 micrometers) and there are typically numerous cilia per cell.
What do cilia and flagella do?
Cilia and flagella are specialized structures found on the surface of cells that help with movement. Cilia are shorter and move in a coordinated manner to move substances along the surface of the cell, while flagella are longer and typically move in a whip-like motion to propel the cell forward.
Flagella are longer and more numerous than cilia?
Flagella are longer, whip-like structures that are typically found in fewer numbers than cilia. They are involved in cell movement and propulsion by generating a wave-like motion. Cilia, on the other hand, are shorter, hair-like structures that are more numerous and are involved in various functions such as movement of materials along the cell surface or sensory reception.
What are 2 types of movement of animal-like protists?
Ciliary movement: Some animal-like protists, such as Paramecium, move by beating hair-like structures called cilia. Flagellar movement: Others, like Euglena, move by using whip-like structures called flagella to propel themselves through their environment.
What structures allow for cell movement?
Cilia and flagella
How do protozoans move'?
Protozoans move with the help Pseudopodia, cilia and flagella. Pseudopodia - Amoeba Cilia - Paramaecium Flagella - Euglena
Is cilia longer than flagella?
No itis not. Flagella are longer than cilia
Cilia and flagella are cell surfaces structed adapted from what?
Eukaryotic cilia and flagella are cell surfaceprojections familiar to ....

Is the Stentor a Cilia or Flagella?
Stentor is a ciliated protozoan, meaning it has cilia for movement.
What three organelles enable eukaryotic cells to move?
The three organelles are cilia, flagella, and pseudopods. Cilia and flagella are structures that extend from the cell surface and help in cell motility, while pseudopods are temporary projections of the cell membrane used for movement in certain cell types.
Does flagella or cilia have a membrane?
Flagella and cilia do not have a membrane of their own. They are extensions of the cell membrane and are composed of microtubules. These structures help with cell movement and sensory functions in various organisms.
What type of movement euglena have pseudopodia flagella or cilia?
Euglina has flagella. Paramesium has cilia. Amoeba has pseudopods
Name three ways in which cilia and flagella differ?
Cilia are shorter and more numerous than flagella. Flagella typically have a whip-like motion, while cilia have a coordinated back-and-forth movement. Functionally, cilia are involved in moving substances along the cell surface, while flagella are used for cell propulsion.
How do the cilia and flagella of protists differ from those of bacteria?
Cilia and flagella in protists are structurally more complex and composed of microtubules arranged in a 9+2 pattern, while bacterial flagella are simpler and made of a single protein called flagellin. Protist cilia and flagella also have a different beating pattern and are involved in various functions like locomotion and feeding, whereas bacterial flagella primarily aid in movement.
What are hollow structures in the cell that sometimes extend from the cell to make up cilia or flagella?
Extensions of the centrioles are what make up cilia and flagella.
