Question

Which cells do comb jellies use to capture their prey?

A) Stinging cells
B) Tentacle cells
C) Cnidocytes
D) Colloblasts

Answer 1

D: Colloblasts

Step-by-step explanation:

Comb jellies lack stinging cells; they are not actually jellyfish, and aren't in the same phylum as them. Instead, they use sticky cells called colloblasts.

Answer 2

D) Colloblasts. Comb jellies use colloblasts to capture prey, which are sticky cells that ensnare rather than sting their targets, distinguishing them from cnidarians that use cnidocytes with nematocysts.

Step-by-step explanation:

Comb jellies, known scientifically as ctenophores, use specialized cells called colloblasts to capture their prey. Unlike the cnidarians that include jellyfish, corals, and sea anemones and use cnidocytes with nematocysts to stun or paralyze their prey, comb jellies have evolved colloblasts for prey capture. Colloblasts are sticky cells found on the tentacles of comb jellies, and they work by adhering to prey rather than stinging it. When prey comes into contact with these cells, it becomes ensnared, allowing the comb jelly to reel its catch towards the mouth for ingestion.

Therefore, the correct answer to which cells comb jellies use to capture their prey is D) Colloblasts.
