Architectural Pattern/Classification and the Phylum Porifera Flashcards
What is Taxonomy?
The science of identifying and classifying organisms according to certain guidelines.
What is a taxon?
A group of organisms sharing a set of characteristics.
What are 6 characteristics of classifying organisms?
- Anatomy, 2. physiology, 3.embryology, 4. molecular, 5. behavior, 6. ecology
Porifera is a phylum that is
sponges.
Cnidaria is a phylum that is
Jellyfish, Coral
Platyhelminthes is a phylum that is
Flatworms
Nematoda is a phylum that is
Roundworms
Mollusca is a phylum that is
Snails, Clams, and Squid
Annelida is a phylum that is
Segmented worms
Arthropoda is a phylum that is
Insects, crustaceans
Echinodermata is a phylum that is
Starfish, sand dollars
Chordata is a phylum that is
Animals with a notocord.
Invertebrate Chordates consist of
Lancelet, tunicate
Vertebrates consist of
Fish, Amphibians, Reptiles, Birds, and Mammals.
The criteria of classification consist of
Symmetry, Grade of Organization, Number of germ layers, Type of body cavity, Segmentation, Special features.
Type of symmetry
Asymmetry, Radial, Bilateral
Grade of Organization categories
- Cytoplasmic, 2.Cellular, 3. Tissue, 4. Organ, 5. Organ system
Number of Embryonic Germ Layers (blastic)
Diploblastic, Triploblastic
Types of body cavity
Acoelomate, pseudocoelomate, coelomate
Segmentation
State of division
Special features such as
Feathers, scales, placenta
Asymmetry has no
central point or axis around body.
Sponges are
Asymmetrical
Radial symmetry examples of animals
Jellyfish, sea anemones, (Cnidarian and Ctenophoria)
