Compare the features of the life of coelenterates and protozoa. Make a conclusion about the level of organization of coelenterates.

Common coelenterates and protozoa:
1) Live in the aquatic environment
2) Have a cellular structure
3) eukaryotes
4) By the type of nutrition, most heterotrophs
5) Full body breathing
Conclusion: The coelenterates and protozoa have common features, but the coelenterates are arranged more complexly: they are multicellular animals, unlike the protozoa, a third non-cellular layer has appeared – the mesoglea. Formed stinging cells in the ectoderm for protection (unconditioned reflex). Body symmetry (radial) has appeared. Hermaphrodites. The ability to regenerate.
