All bacteria do have flagella and flagella occurs on both Gram Negative bacteria and Gram Positive bacteria and are found on many species of bacilli but rarely found on cocci.

Two main functions of flagella and cilia are to receive the signals from nearby cells and act as an antennae for the cells.

The flagella also acts as sensory organs in order to detect temperature and pH changes.

The eukaryotic cells move through flagellar-dependent swimming and actin-dependent cell migration, both of which are used by animal cells and unicellular eukaryotes alike.

Flagella is important to animal cells as they help in movement and locomotion.

Sperm cells also have and require flagella to allow the sperm to swim through the females reproductive tract so that it can reach towards the ovum and carry fertilization.

Flagella moves through a whip like motion and through the surrounding fluid and the movement is referred to as a ciliary beat or flagellar.

The dynein motor proteins generate the motive force needed to bend the flagellum and cause it to move in the whip like motion.

The function of flagellum is for chemotaxis and to enable the movement of cells.

Cells have flagella to enable movement and chemotaxis.

The cell movement is the best function of it's flagellum and are found in some eukaryotes and prokaryotes and the prokaryotic flagellum spins and creates forward movement by a corkscrew shaped filament.

Prokaryotes can also have either one or even several flagella, spread out around the cell or be localized to one pole.

The difference between prokaryotic and eukaryotic flagella is in their movement and structure as eukaryotic flagella are microtubule-based structures, which are attached to the cell at the cell membrane through basal bodies while prokaryotic flagella are located outside of the plasma membrane.

The primary difference between cilia and flagella in eukaryotes is that cilia beat in a synchronized rhythm, whereas flagella beat independently and cilia are only found in eukaryotic cells.

The proteins that are in eukaryotic flagellum are the major motor proteins, kinesin-2 and osm-3 (which transport particles from the cell body to ciliary tips) and cytoplasmic dynein 1b (which transports particles from ciliary tips to the cell body).

The cells that have a flagellum are the gametes of algae, fungi, mosses, slime molds, and animals.

And the flagellum is the hairlike structure that acts primarily as an organelle of locomotion in the cells of many living organisms.

The structure of the flagellum is a coiled, thread-like structure, sharp bent, consisting of a rotary motor at its base and are composed of the protein flagellin.

And a shaft also exists between a hook and a basal body passing through the protein rings in the cell membrane.

Cells provide structure and support to the body of an organism.

The cell interior is organized into different individual organelles surrounded by a separate membrane.

The nucleus (major organelle) holds genetic information necessary for reproduction and cell growth.

A cell can move without a flagella as many bacteria do glide over surfaces without the use or aid of a flagella.

Gliding motility is the ability of certain rod-shaped bacteria to translocate on surfaces without the aid of external appendages such as flagella, cilia, or pili.

The function of the flagella in a eukaryotic cell is to serve motility, transport and sensory functions.

The function of eukaryotic and prokaryotic flagella is cell movement.

The difference between eukaryotic and prokaryotic flagella is in structure and movement as eukaryotic flagella are microtubule-based structures, that are attached to the cell at the cell membrane through the basal bodies while the prokaryotic flagella are located outside of the plasma membrane.

The differences between prokaryotic and eukaryotic flagella are the prokaryotic flagella that are designed to perform rotatory (clockwise and counter clockwise) movements

And the Eukaryotic flagella perform undulatory (back and forth) movements.

The prokaryotic flagellum has three parts- Basal body, Hook, Filament. While the Eukaryotic flagellum has two parts- Basal body and shaft.

The reason why eukaryotic flagella differs from prokaryotic flagella is because eukaryotes, the flagellum beats in a whip-like fashion, whereas in prokaryotes the flagellum is an unmoving cork-like entity, relying on the motor at its base for torque.

And the structure of the flagella is also complex and at the base the rotor sits inside the cells membrane.

Eukaryotes use flagella to move and propel the cell through a fluid medium.

Flagella differs from bacterial flagella in that bacterial flagella do not have dynein or microtubules in their flagella and they move in a rotary mechanism and the flagella in eukaryotes have dynein and microtubules that move with a bending mechanism.

Bacterial flagella is similar to eukaryotic flagella as the structure and the function of the bacterial flagella are the same as the eukaryotic flagella.

Eukaryotic flagella arises from a basal body or centriole and they are surrounded by a specialized flagella and membrane after they project from the cells surface.

Cilia in eukaryotic cells are short hair like structures that are used to move entire cells or substances along outer surfaces of the cell and Flagella are long and wavy structures that extend from the plasma membrane and are used to move an entire cell.

Eukaryotic cells have both cilia and flagella which are motile organelles that are built on a scaffold of doublet microtubules and are powered by dynein ATPase motors.

The function of the flagellum in a eukaryotic cell is to serve motility, transport and sensory functions.

The function of the flagellum is to enable movement and chemotaxis.

Bacteria can also have one flagellum or even several and they can also be either polar meaning one or several flagella at one spot or peritrichous meaning several flagella all over the bacterium.

Flagellums are a hairlike appendage which protrudes from certain plant and animal sperm cells, from fungal spores, and from a wide range of microorganisms to provide motility.

Many protists with flagella are known as flagellates.

A microorganism may have from one to many flagella.

Flagella are the organelles for bacterial locomotion.

These supramolecular structures extend from the cytoplasm to the cell exterior and are composed of three major structural elements, the basal body, the hook and the filament.

The cell type in animals that has a flagellum is the sperm cell, which is the male sex cell.

A flagellum is a hair-like appendage that extends from a cell and is used to move that cell through its environment.

Flagellum is a lash-like appendage that protrudes from the cell body of certain bacteria.

Some DNA bacterial viruses use flagella to attach to the host cell.

This contact with the flagellum facilitates concentration of phage particles around the receptor on the bacterial cell surface.

Flagella propel the cell by spinning around their axis in a corkscrew motion.

They move in response to a chemical concentration gradient, indicating a sensory feedback regulation system.

This is the basis for bacterial chemotaxis.

The only flagellated cell in humans is the sperm cell that must propel itself towards female egg cells.

In humans and other mammals, several widespread diseases are caused by flagellates.
