हिन्दीThe cell structure illustrated in Figure 4.7 is characteristic of Phylum Coelenterata. Which of the following functions is NOT directly associated with this structure?
Correct answer · Option 4
Osmoregulation and excretion of nitrogenous wastes
Explanation
Figure 4.7 illustrates a cnidoblast (cnidocyte) containing a nematocyst. Cnidoblasts are used for anchorage, defense, and capture of prey, but NOT for osmoregulation and excretion (which are functions performed by flame cells in platyhelminthes or nephridia in annelids).
