Radial Symmetry, Nematocysts, Medusae, and Polyps Associated with Which Animal Phylum?

Answer:
The terms radial symmetry, nematocysts, medusae, and polyps are characteristics commonly associated with the animal phylum Cnidaria. Cnidarians are a diverse group of animals that include jellyfish, corals, sea anemones, and hydras.

  1. Radial Symmetry: Cnidarians exhibit radial symmetry, which means their bodies are arranged around a central axis, like the spokes of a wheel. This body plan allows them to capture food from any direction.

  2. Nematocysts: These are stinging cells that cnidarians possess on their tentacles. Nematocysts are used for defense and capturing prey by injecting toxins into their target.

  3. Medusae and Polyps: Cnidarians have two main body forms - medusae and polyps. Medusae are the umbrella-shaped, free-swimming jellyfish forms, while polyps are vase-shaped and usually sessile (attached to a substrate).

Overall, the presence of radial symmetry, nematocysts, medusae, and polyps are key characteristics that define the phylum Cnidaria in the animal kingdom.
