Order Rodentia - ANSWER rodents
Order Testudines - ANSWER turtles
Kingdom Animalia - ANSWER contain organisms that are multicellular eukaryotes
including vertebrates and invertebrates.
types of symmetry in animals - ANSWER asymmetrical, radial, bilateral
Define bilateral symmetry - ANSWER A term that means that right and left sides of the
body are mirror images
, Advantages of bilateral symmetry in animals - ANSWER Improved mobility, faster
information processing since brain is close to the front.
Efficient movement.
Specialized appendages.
Define radial symmetry - ANSWER arrangement of body parts in a circle around a
central axis
Advantages of radial symmetry - ANSWER attack prey from all sides, defend from all
sides, uses less energy
Protostome - ANSWER an animal whose mouth is formed from the blastopore
blastopore - ANSWER the opening of the central cavity of an embryo in the early stage of
development.
Deuterostomes - ANSWER Animals in which the blastopore becomes the anus during
early embryonic development
Zygote - ANSWER fertilized egg
morula stage - ANSWER solid ball of 16 cells that resembles a mulberry
Blastula - ANSWER The hollow ball of cells marking the end stage of cleavage during
early embryonic development
Gastrula - ANSWER An embryonic stage in animal development encompassing the
formation of three layers: ectoderm, mesoderm, and endoderm.
Phylum Porifera - ANSWER aka sponges; means animal that contains holes; are sessile
feeders (stuck to the ground, eating what comes near them); body symmetry: asymetric
eg. yellow tube sponge
Central Dogma of Biology - ANSWER DNA-transcription-RNA-translation-protein
Phylum Platyhelminthes - ANSWER flatworms, flukes, tapeworms
Class Turbellaria - ANSWER free-living flatworms. Eats via pharynx tube. Regenerative.
Simple brain.
Class Trematoda - ANSWER Flukes: endoparasites of vertebrates; most complex life
cycle of any animal.
Class Cestoda - ANSWER tapeworms, endoparasites. No digestive system, avoid
nutrients through their skin. Each segment is a complete animal called a proglottid.
Proglottids - ANSWER One of the segments of a tapeworm, containing both male and
female reproductive organs
