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 is a phylum containing over 9,000 species found only in aquatic and mostly marine environments. All cnidarians have radial symmetrical. There are two major body forms among the Cnidaria-the polyp and the medusa. Sea anemones and corals have the polyp form, while jellyfish are typical medusae.When you look at them, you can see that these body forms are the same except that one is upside down.nidaria do not have a brain or groups of nerve cells ( ganglia ). The nervous system is a decentralized network (ânerve netâ), with one or two nets present. They do not have a head, but they have a mouth, surrounded by a crown of tentacles. The tentacles are covered with stinging cells (nematocysts).
