Question

Prokaryotic and eukaryotic flagella differ in
A. Type of movement and position
B. Microtubular organisation and function
C. Location and mode of functioning
D. Microtubular organisation and type of movement.

Answer 1

Hint: Prokaryotic and eukaryotic flagella mainly differs in their structure and movement. Eukaryotic flagella are microtubule-based structures, which are attached to the cell at the cell membrane through basal bodies while prokaryotic flagella are located outside of the plasma membrane.
Complete answer: In this question, we have asked about the difference between eukaryotic and prokaryotic flagella. The difference between prokaryotic and eukaryotic flagella are following:

Sr. No.	Eukaryotic flagella	Prokaryotic flagella
1	Eukaryotic flagella run in a bending movement.	Prokaryotic flagella run in a rotary movement.
2	It consists of tubulin proteins.	It is made up of flagellin proteins.
3	Large and thick	Small and narrower
4	It moves back and forth means undulatory movement.	It moves clockwise and anti - clockwise means rotatory movement.
5	They do not have microtubules.	They are made up of microtubules.
6	Eukaryotic flagellum has two parts- Basal body and shaft.	Prokaryotic flagellum has two parts- Basal body, Hook, Filament.
7	Eukaryotic basal body bears rootlets.	Prokaryotic basal body bears rings.
8	Eukaryotic flagella is covered by membranous sheath which is derived from plasmalemma.	Prokaryotic flagella are not covered by a membranous sheath.

As we can see from the table that eukaryotic and prokaryotic flagella mainly differ in their structure and they have different types of movement.

So, the correct option is D. Microtubular organisation and type of movement.

Note:
Eukaryotic and prokaryotic flagella both are made up of 9 + 2 arrangement. Only non - motile flagella have a 9+0 arrangement. Non- motile acts more like a sensory receptor.
