Question

Match the following. Identify the correct match between Set-I and Set-II.

Set-I	Set-II
A) Stichonematic	I) Flagellum has two or more rows of lateral appendages
B) Pantonematic	II) Flagellum has no lateral appendages and terminal filament
C) Acronematic	III) Flagellum bears one row of lateral appendages
D) Anematic	IV) Flagellum does not lateral appendages and terminal part of the acroneme is naked

• A. A- III, B- I, C- IV, D- II
• B. A- IV, B- I, C- III, D- II
• C. A- III, B- II, C- IV, D- I
• D. A- II, B- I, C- III, D- IV

Answer 1

Answer: (A)

A- III, B- I, C- IV, D- II

A) Flagella with the small hair-like structure called mastigonemes on one side/row of the flagella are called as stichonematic flagella. It is found in euglena.

B) Flagella with hair like structure called mastigonemes in two rows are called as stichonematic flagella.

C) In Acronematic, flagellum has no mastigonemes, i.e., it ends with a fine filament.It is found in Chlamydomonas.

D) An anematic flagellum is simple without mastigonemes and the distal ends of the flagellum end as a terminal 'naked', axial filament.

It is found in cryptomonas.

Hence, the correct is option A.
