BStinging cells that can be used in defense or prey capture
CCells that secrete a sticky substance for prey capture
DPhotosensitive cells that allow an organism to detect light levels
ECells that contribute to the skeletal structure of an organism

Verified Answer :

Final answer:

Cnidocytes are specialized stinging cells found in cnidarians, equipped with nematocysts that can sting and inject toxins for defense and prey capture. These cells are crucial for the survival of organisms like jellyfish and sea anemones. They serve important roles in both protection and feeding strategies.


Explanation:

What Are Cnidocytes?

Cnidocytes are specialized cells found in cnidarians, which include organisms such as jellyfish, sea anemones, and corals. These cells contain unique organelles called nematocysts, which can deliver a potent sting to potential predators or prey. When activated, the nematocysts eject a barbed thread that can penetrate and inject toxins into the target, making cnidocytes essential for defense and prey capture.

Cnidocytes serve several important functions in the life of a cnidarian:

  • Defense: They protect the organism from predators.
  • Prey Capture: They help to immobilize or kill prey, allowing the cnidarian to feed.
  • Locomotion: While not their primary function, the reaction of cnidocytes can also aid in the movement of the organism.

In summary, cnidocytes are critical cells in the survival and functionality of cnidarians, making them unique among marine life.
