Study Guide 3
Study guide for bio112 exam #3 The Animals:
General characteristics: 1. multicellular heterotrophs 2. Divers in form 3. No cell walls 4. Active movement 5. Sexual reproduction 6. Embryo development(zygote>morula>blastula>blastopore/gastrula)
Parazoans VS Eumetazoans. Eumetazoans as triploblastic organisms.
Eumetazoan 4 key body plans 1. Radial and bilateral symmetry 2. Body cavities(bilateral organisms only); General importance of(digestion/reproduction). Acoelomic cavity, Pseudocoelomic cavity, Coelomic cavity. 3. Segmentation(most are Coelomic, only mollusks are not). 4. Protostomes and Deuterostomes( both are bilateral, Coelomic and segmented organisms).
Phylum: Porifera-The sponges------------------------Parazoans
Phylum: Cnidaria-jellyfish, anemones, coral------Eumetazoans with radial symmetry.
Phylum: Platyhelminthes-The flat worms----------Bilateral symmetry with acoelomic cavity.
Phylum: Nematoda-The round worms--------------Pseudocoelomic cavity.
Phylum: Mollusca-Gastropods/Bivalves/Cephalopods------Coelomic cavity, first heart/respiratory system.
Phylum: Annelida-Earth worms/marine worms/leeches----Coelomic and segmented.
Phylum: Arthropoda-Chelicerata/mandibulate. crustaceans/spiders/insects------exoskeleton, jointed appendages, flight.
Phylum: Echinodermata-starfish/sea urchins/sand dollars/sea cucumbers—Deuterostome development BilateralRadial, Endoskeleton, water vascular system.
Phylum: Chordata- Non-vertebrate chordate(no skull) and vertebrate chordate(have skull). General chordate features: (1) The Notochord (2) Dorsal nerve cord (3) Post anal tail General vertebrate chordate features:(1) Skull (2) vertebral column (3) Internal organs(multiple endocrine glands) (4) Internal endoskeleton, framework of cartilage or bone, (5) Neural crest-(gill arches/sensory ganglia/schwann cells/Adrenal gland).
Vertebrate chordates:
The Fish-General characteristics: Gills with one-way
