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 are diploblastic animals, in other words they have two main cell layers, while more complex animals are triploblasts having three main layers. The two main cell layers of cnidarians form epithelia that are mostly one cell thick, and are attached to a fibrous basement membrane, which they secrete.n the Cnidaria sexual reproduction often involves a complex life cycle with both polyp and medusa stages. For example, in Scyphozoa (jellyfish) and Cubozoa (box jellies) a larva swims until it finds a good site, and then becomes a polyp.
