The flagella originates from which part of the cell?
Correct answer: A. Basal body
- A. Basal body
- B. Cell membrane
- C. Cell wall
- D. Capsule
Explanation
Option A is correct as cilia and flagella originate from their basal bodies embedded in the cytoplasm. Basal bodies have the same circular arrangement of microtubule triplets as centrioles. Option B is incorrect as the cell membrane is the structure into which the basal body is embedded. Option C is incorrect since the basal body is embedded in the cell wall and cell membrane. Option D is incorrect since the capsule may cover the cell wall in a bacterial cell, so the basal body becomes embedded in it too.
