Which of the following statements regarding cilia is NOT correct?
Correct answer: B. The organized beating of cilia is controlled by fluxes of Ca2+ across the membrane
- A. Cilia contain an outer ring of nine doublet microtubules surrounding two singlet microtubules
- B. The organized beating of cilia is controlled by fluxes of Ca2+ across the membrane
- C. Cilia are hair-like cellular appendages
- D. Microtubules of cilia are composed of tubulin
Explanation
Option B is incorrect because the organized beating of cilia is not controlled by fluxes of Ca but by the sliding of microtubule doublets.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
