High School Biology Experiment Ideas. c and plants. High school level biology covers all aspects of biology, including animals, plant life and humans. That should mean it's easy to come up with a science fair project or a classroom research project, but the amount of topics sometimes makes it even harder.
Characteristics of Phylum Coelenterata(CNIDARIA). Phylum coelenterata characteristics. 1. Dipoblastic body with two layers of cells, outer layer called ectoderm or epidermis and the inner layer known as the endoderm or gastrodermis. 2. Phylum coelenterata characteristics is they have a single opening into the body which acts as both the mouth and anus which functions in taking food and expelling wastes.
Cnidaria: Life History and Ecology. Cnidarian ecology is a complex subject indeed, because it is cnidarians, in particular corals, that are the builders of some of the richest and most complex ecosystems on the planet, coral reefs.Other cnidarians are important as predators in the open ocean. Cnidarians generally occupy two major niches.They may use their cnidocysts to trap prey items. On the other hand, many cnidarians, anthozoans in particular, depend on zooxanthellae, symbiotic dinoflagellates within the tissues, to survive.ther cnidarians are important as predators in the open ocean.
