Flagella with single strand and composed of flagellin is found in:
1 prokaryotes
2 eukaryotes
3 both (a) and (b)
4 none of the above
Explanation:
Exp:A Prokaryotic flagellum spins, creating forward movement by corkscrew shaped filament. Prokaryotes have one or several flagella, localized to one pole. It is composed of flagellin proteins. ATP synthase not required in prokaryotic because. flagellum protein utilize the energy by proton process power.
4 Ans: b Exp: Exp:B Prokaryotic flagella are composed of protein "flagellin" arranged in helical chains. That intertwine and form a helix around at to identify certain pathogenic bacteria unlike eukaryotes, the filaments are not covered by membranes or sheath. Each filament has rotator motor at its base which turn clockwise or counterclockwise it provides motility to bacteria.

The filament in flagellum can rotate by:
1 \(360^{\circ}\)
2 \(60^{\circ}\)
3 \(120^{\circ}\)
4 \(80^{\circ}\)
Explanation:
Exp:A Bacterial flagella are helical filament, a proximal at its base associated with the cell wall and cytoplasmic membrane and structures contains flagellin. Flagellum rotates in clockwise or anticlockwise direction. Flagella rotate clockwise as bacteria rotate flagella clockwise at \(360^{\circ}\).

In the below diagram, identify the part which connects the peripheral microtubules to the central sheath.
1 Plasma membrane
2 Interdoublet bridge
3 Central microtubule
4 Radial spoke
Explanation:
Exp:D Radial spokes connected peripheral microtubules to the central sheath of cilia and flagella of eukaryotic cells. There are nine radial spokes. Radial spokes are made up of protein and least 23 proteins that works as a mechanochemical transducer between central - pair apparatus and peripheral microtubule.
