Answer 2

Answer:

The correct option is (4) it consists of flagellum and tubulin proteins.

Explanation:

• Option (4) is accurate because eukaryotic flagella lack flagellin in their basal body. Prokaryotes contain flagellin.
• The cilia and flagella, two moving cell appendages, are also closely related to microtubules.
• Both of these appendages are present on several eukaryotic cells.
• Only 0.25 m in length, cilia are shorter than flagella.
• They might shift the surrounding fluid over the cell's surface (for example, protists or cells lining tubes through which eggs move, the oviducts).
• The length and diameter of eukaryotic flagella are 100–200 m and 0.25 m, respectively. (Eukaryotic flagella differ greatly from prokaryotic flagella in both form and function.)
• Through its watery environment, they may pull or push the cell (for example, protists or sperm).
• Both cilia and eukaryotic flagella are made of specialised microtubules and have the same internal architecture; however, the length and beating pattern of each are different.
• The filament in a bacterial flagellum is made of the globular protein flagellin, which arranges itself into a hollow cylinder.
• It weighs between 30,000 and 60,000 daltons.
• The main component of bacterial flagella is flagellin, which is abundant on almost all flagellated bacteria.
• Flagellin was once thought of as a virulence factor that aids in the adhesion and invasion of host cells, but it has now been discovered to be a powerful immune activator that shapes both the innate and adaptive immune systems during microbial infections.
