How many rings are found in the flagella structure of Gram +ve bacteria?

Solution(By Examveda Team)

2 rings are found in the flagella structure of Gram +ve bacteria.
The bacterial flagellum is a motile organelle composed of thousands of protein subunits.
The filamentous part that extends from the cell membrane is called the axial structure and consists of three major parts, the filament, hook, rod, and other minor components.
The number of rings varies depending on the membrane systems: four rings in most Gram-negatives and two rings in Gram-positives exemplified by B. subtilis.
