Amphitrichous flagellation hasA. Flagella absen

The correct answer is C. Flagella at both the ends.
Amphitrichous flagellation refers to a type of flagellar arrangement found in some bacteria and other microorganisms. In this arrangement, a single flagellum is present at each end of the cell, hence the term "amphitrichous" (from Greek "amphi" meaning both and "trichous" meaning hair or flagellum).
Types of Flagellation in Bacteria:
1. Monotrichous:
o A single flagellum is located at one end of the cell.
2. Lophotrichous:
o A tuft or cluster of flagella arises from one or both ends of the cell.
3. Amphitrichous:
o One flagellum at each end of the cell.
4. Peritrichous:
o Flagella are distributed all around the surface of the cell.
Why Not the Other Options?
• A. Flagella absent: This is not amphitrichous flagellation. The term specifically describes the presence of flagella.
• B. Flagella at one end: This is characteristic of monotrichous flagellation, not amphitrichous.
• D. Flagella all around: This describes peritrichous flagellation, where flagella are found all over the surface of the cell.
Amphitrichous flagellation refers to having flagella at both ends of the cell, making the correct answer C. Flagella at both the ends.
