Vedclass · Answer

(C) Nematocysts are specialized stinging cells found in the tentacles of $Hydra$.When a prey item comes into contact with the tentacles,the nematocyst is triggered to discharge.Upon stimulation,the operculum opens,and the thread-tube is everted,which pierces the prey and injects toxins to paralyze it.Therefore,the ejection is a response to physical or chemical contact,not a conditioned reflex,and they are not re-used after discharge.
