3)to aid in digestion
4)to inject venom

Answer 1

The primary function of nematocysts is 4) to inject venom. Nematocysts are specialized cells found in cnidarians (such as jellyfish, sea anemones, and corals) that contain a coiled thread and a venomous toxin. They are used for capturing prey and for defense against predators. When triggered, the nematocyst can rapidly eject its thread to deliver the venom.
