Eukaryotic flagella contain microtubules and an associated complex of motor and connective proteins collectively known as the axoneme.

Eukaryotic flagella are made of microtubules and characterized by the canonical 9+2 arrangement of microtubules in which 9 doublet microtubules surround a central pair of singlet microtubules.

The thing that is different about eukaryotic flagella is that eukaryotic flagella is covered by membranous sheath which is derived from plasmalemma.

The prokaryotic flagella are not covered by a membranous sheath.

The eukaryotic and prokaryotic flagella differ mainly in their structure and they also have different types of movement.

The eukaryotes and prokaryotes have flagella as flagella is a structure that exists on both eukaryotic and prokaryotic cells and serves the purpose of moving the cell through the fluid environment in which that cell is found in.

Although the structure, mechanism and composition by which the flagellum functions in these two different cells differ greatly.

The flagella enables movement and chemotaxis.

The function of eukaryotic flagella 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.

Perhaps the most widespread is giardiasis caused by the intestinal parasite Giardia lamblia, with symptoms such as diarrhea (water and nutrient loss) and painful abdominal cramps.

A polar bundle of flagella can drive bacterial swimming by pushing, pulling, or coiling around the cell body.

Sperms have flagellum for their locomotion.
