The thread-like structures that make up the body of a fungus are called: ((MCAER 2014))

✅Explanation: Peritrichous bacteria have flagella that are distributed evenly around their entire surface. This arrangement allows for efficient movement and navigation in their environment.

📌 Other Options Explanations:
-Option A: Monotrichous bacteria have a single flagellum at one end.
-Option B: Amphitrichous bacteria have a single flagellum at each end.
-Option D: Atrichous bacteria do not have any flagella.

🔑Key Points:
-Flagella are hair-like structures protruding from the cell surface and has the primary function of locomotion.
-It is present in both prokaryotic and eukaryotic motile cells but differ in structure.
-Bacterial flagella is made up of flagellin protein.

✏It has 3 major structural elements:
-Basal body – remains enclosed in the cell envelope and functions like rotary motor.
-Hook – is the attachment of the filament to the basal body near the cell surface.
-Filament – is the helical structure that rotates clockwise or anti-clockwise to work like a propeller.

✏On the basis of number and position of flagella, bacteria can be divided into:
-Atrichous – do not have any flagella. Example – Lactobacillus.
-Monotrichous – have a single polar flagella. Example – Vibrio cholerae.
-Amphitrichous – have a single flagella at each end. Example – Campylobacter.
-Lophotrichous – have a tuft of flagella at one end. Example – Spirillum.
-Peritrichous – have numerous flagella distributed all over the body. Example – Salmonella.
