Zoology Final

3 types of symmetry

radial/ circle

bilateral/ distinct left and right sides

asymmetry

scientific name example with binomial nomenclature

Homo sapiens. italicized - includes genus and species

diff methods of reproduction

asexual/budding (child grows from bud on parent), fission ( parent splits), regeneration, parthenogenesis ( egg develops into a female without fertilization during tough times)

sexual/ internal or external

planria

they are hermaphrodites, and can produce sexually and asexually through fission

ventral

refers to the front for humans, therefore on animals it is the belly side

three types of skeletons

exoskeleton, endoskeleton, hydroskeleton-soft bodied organisms, incompressible fluid maintains body cavity shape

animals cells

do not have a cell wall

animal phylums

porifera/ pore bearing

Cnidaria/ stinging cells, think cni-sting

platyhelminthes/ flat worm

nematoda/ round worm, hema/nema (round)

Annelida/ little rings

arthropoda/ jointed feet

mollusca/ soft bodied

echinodermata/spiny skin

chordata/ cord bearing
