Yuav ua li cas symmetry ua parazoa muaj?
Porifera thiab Placozoa
Ntawm cov pab pawg no tsuas muaj txoj sia nyob, uas yog phylum Porifera, thiab Trichoplax hauv phylum Placozoa. Parazoa tsis qhia lub cev sib luag (lawv asymmetric); tag nrho lwm pab pawg ntawm cov tsiaj muaj ib co symmetry. Tam sim no muaj 5000 hom, 150 yam uas yog dej tshiab.
Puas asymmetry tsuas pom nyob rau hauv parazoa?
Asymmetry tsuas yog pom hauv Parazoa. Radial symmetry yog qhov zoo tshaj plaws rau kev ua neej nyob ruaj khov Ob tog symmetry tso cai rau kev taw qhia.
Qhov txawv ntawm parazoa thiab Eumetazoa yog dab tsi?
Parazoa Versus Eumetazoa
