Cilia space short, hair-like structure, current in large numbers in a cell, while flagella are long, hair-like complex structure and also are few per cell. Cilia and also flagella are hair-like appendages, extending through the surface of the life cell, they differ in their mode of beating, size, and number.

You are watching: How are flagella and cilia alike

Cilia and also flagella space the locomotory structure, which is the expansion of the plasma membrane of the cell. As well as the locomotion, castle also help in various other processes like respiration, excretion, circulation, etc. They also take part in catching food. This both are uncovered in eukaryotic bio cells, yet in prokaryotic cells only flagella

Both of this appendages are found in eukaryotic bio cells, but in prokaryotic cells only flagella space present. Although this appendages room not uncovered in plants. In the following article, we will talk about the difference in between these 2 structures.

Definition that Cilia

Cilia room short, slender, hair-like appendages expanding from the surface ar of the cell. This are existing in nearly all eukaryotic cells. Castle play a significant role the cell and overall human body development.

Cilia are most active during the cell cycle progression and also proliferation. The broad of the cilium is less than 1 µm, and the size varies from 1-10 µm.

Cilia are broadly divided into two varieties – Motile and Non-motile. Motile or moving cilia are mainly present in lungs, middle ear, and also respiratory tract. These kind beat rhythmically. Their job-related is to store the airways clean of mucus and dust, due to which it is simple to breathe freely and also without any type of irritation. Castle are also helpful in the motion of the sperm.


Motile cilia consists ciliary axoneme, i m sorry is concerned as the microtubular backbone, they have 9+2 arrangement of the ciliary axoneme and is surrounded by the plasma membrane. In this arrangement, the ripe fused pairs of microtubules i ordered it in a circle, when the 2 unfused microtubules are present in the facility of the circle.

The eight ‘dynein‘ which room attached come the microtubules, act together the molecule motors. The defect in the dynein arms causes male infertility, problems in the respiratory tract.

Non-motile cilia likewise called as main cilia play their role in receiving signal from various other cells or surrounding fluids, by acting as the antenna for the cell. For instance in the kidney, the cilia send signals to the cells around the circulation of urine.

Even in the eye, the non-motile cilia supports the transportation of critical molecules from one finish of the photoreceptor that the retina come the other. Non-motile cilia have 9+0 microtubular arrangement.

Definition of Flagella

Flagella are the complex, hair-like filamentous structure, prolonging through the cabinet surface. Flagella are composed protein like flagellin, installed in the cell envelope. They space responsible for motility. They can be around 5-16 µm in length and 12-30 nm in diameter.

Flagella space of three types – bacterial flagella, archaeal flagella, eukaryotic bio flagella. Bacterial flagella are found in Salmonella typhi, E. Coli. They deserve to be one, 2 or countless flagella per cell. These have the helical filamentous structure that rotates prefer screws. These provide motility come bacteria.

Archaeal flagella present similarity v that of bacter flagella but lack a main channel. Eukaryotic flagella space the facility projections, that beat ago and forth. An example is the sperm cell, which propels itself with the female reproductive tract by utilizing its flagellum.


Usually, flagella consist of Hook, Filament and Basal human body in your body parts. The filament is the external part of the cell; the hook is in the cell envelope, and also basal human body is attached come the cytoplasmic membrane, through the ring-like structures. Their duty is adhesion, signal transduction, sensation, movements.

Key Differences in between Cilia and Flagella

Given below are the crucial differences in between the cilia and flagella:

Cilia room the microscopic, slender, brief hair like structure present all at once on the surface of the cell, and also thus assistance the locomotion the the cell, top top the various other hand, flagella are much longer and few in number, complex, filamentous structure, prolonged through the cabinet surface.Cilia are found in eukaryotic bio cells only, they are present as whole on the cabinet surface and also are shorter, when flagella are longer and also are few (less 보다 10) in numbers, they are discovered in prokaryotic and in eukaryotic cells.Cilia beat coordinately and also show rotational motion and also are very fast moving also, ~ above the other hand, flagella show whip-like, sinusoidal, undulating, elevation movement, but are slow.Cilia play your leading role in locomotion, aeration (respiration), excretion, circulation, etc., while flagella are valuable in locomotion only.


Cilia and also flagella share part common attributes like castle arise native the small granular structure called the basal body. Both space the outgrowth of the plasma membrane that the cell. Cilia and also flagella covers the central filament referred to as an axoneme. The axoneme includes eleven microtubules. Nine are existing in pairs called as the doublet, and two that them current in the facility are the singlet. This is referred to as 9+2 microtubular arrangement. The drift in the microtubules that the axoneme causes the movement in the cilia and also flagella. The axoneme includes proteins favor dynein, tubulin, nexin.In part organisms prefer protozoans and also metazoans, it helps in catching food.Mainly offer as locomotory organs.Also help in respiration, circulation, and excretion.

Cilia and also flagella space the locomotory framework of the prokaryotic and eukaryotic cells, yet apart from it, they also perform definitely a physiological process like circulation, respiration, locomotion, excretion. Being structurally same, the function that distinguish them indigenous each other is their number, size and beating mode.
