Classification groupings in order | Kingdom, Phylum, Class, Order, family, Genus, Species |
98% of animal species, radial and bilateral symmetry, no backbone or cells walls | Invertebrates |
2% of animal species, bilaterial,internal skelton,sensory organs, nervous & respitatory | Vertebrates |
Protomsome | 1st opening that develops from blastopore becmes a mouth. |
Deutersome | Mouth develops from the second opening and the anue develops from blastopore |
Coelomate | "true coelom",have a fluid filled body cavity completelty surrounded by tissue from mesoderm |
Acoelemate | solid bodied; lacking a cavity between the gut and outer wall. NO BODY CAVITY |
Pseudocoelomate | body cavity lined by tissue derives from mesodern and ednoderm; not completely lined. |
Asymmetry | no line of bisection exists that could devide the organism into similar-looking halves |
example of asymmetry | phylum Poriefera |
Radial symmetry | where more than one hypothetical bisection can be visualized. |
example of radial symmetry | Cnidaria; Echinodermata |
Bilateral symmetry | only one hypothetical bisection can be visualized. |
example of bilateral symmetry | phyla of most animals |
trichinosis | food-borne disease caused be a microscope parasite. Undercooked meat; ex. hookworm |
