Question

Which one of the following is incorrect?

• A. Nematocyst$\to$Cnidaria
• B. Colloblast $\to$ Ctenophora
• C. Trichocyst$\to$Ciliata
• D. None of the above

Answer 1

Answer: (D)

None of the above

As all the respective characters are specialised to the phylum such as the Cnidarians have nematocysts in their cnidoblasts for capturing prey and for defence, Ctenophora have colloblast in their tentacles to capture prey and ciliates release trichocysts in response to stimuli. The relation is well-established to the respective phylum.

So, the correct answer is 'None of the above'.
