Q.
Identify the correct statements
A) Bacterial flagella do not show 9+2 configuration in their ultra structure.
B) Bacterial flagella composed of both proteins and carbohydrates.
C) All the cocci and bacilli are non-motile.
D) Flagellar movement in bacteria is rotation
Solution:
Bacteria are ubiquitous prokaryotes, i.e., they occur anywhere and everywhere, in water, in air, in soil, in all living organisms except the pits of volcanoes, deep strata of rocks, tops of high mountains and
blood of healthy animals. Some thermophilic bacteria can withstand the temperature upto 78°C,their flagella do not show 9+2 configuration.
Flagella: These are long thread-like structures concerned with the motility of some bacterial
The flagellum consists of identical (3-8) sub-units called flagellin (unique protein molecules) arranged helically along the axis to give a hollow tube. It has no definite membrane. The flagellum is connected by a unique terminal hook, which in turn is attached to the basal body (blepharoplast). The 360° rotation of flagellum induces the cell to spin and move forward.
