Ua ke ob lo lus tsim lub npe scientific ntawm a tshwj xeeb hom kab mob . Ib hom yog ib pawg zoo sib xws kab mob uas tuaj yeem sib koom ua ke thiab tsim cov xeeb ntxwv uas tuaj yeem ua phooj ywg thiab yug me nyuam. Prokaryotes yog unicellular kab mob leej twg yog cell tsis muaj anucleus.
Ntxiv mus, dab tsi yog hom kab mob sib txawv?
Hom kab mob
- Kab mob. Hauv qhov yooj yim tshaj plaws, cov kab mob tuaj yeem yog cov kab mob, DNA molecule uas muaj cov ntaub ntawv genetic qhwv nyob rau hauv aprotective plasma membrane.
- Archaea.
- Eukarya.
- Kab mob.
- Bees.
- Tapeworms.
- Loj Dawb Shark.
Tsis tas li ntawd, 6 hom kab mob tseem ceeb yog dab tsi? Cov Rau Kingdoms: Nroj tsuag, Tsiaj txhu, Protists, Fungi, Archaebacteria, Eubacteria. Tej zaum koj yuav paub zoo nrog cov tswv cuab ntawm lub nceeg vaj no vim nws muaj tag nrho cov nroj tsuag uas koj tau paub - paj paj, mosses, thiab ferns. Nroj tsuag yog tag nrho cov multicellular thiab muaj cov hlwb complex.
Tsuas yog li ntawd, 4 hom kab mob yog dab tsi?
Ntsiab Lus
- Cov kab mob kis tau muab faib ua xya hom: kab mob, archaea, protozoa, algae, fungi, kab mob, thiab kab mob ntau yam kab mob (helminths).
- Txhua hom muaj cov yam ntxwv ntawm cov cellular muaj pes tsawg leeg, morphology, txhais tau tias ntawm locomotion, thiab kev yug me nyuam.
Dab tsi ua rau lub cev muaj sia?
Ib kab mob tej zaum yuav raug txhais raws li ib tug sib dhos ntawm molecules ua hauj lwm raws li ib tug ntau los yog tsawg ruaj khov tag nrho uas exhibits lub zog ntawm lub neej. Cov lus txhais txhais tau dav dav, siv cov lus xws li "txhua yam kev nyob, xws li cov nroj tsuag, tsiaj txhu, fungus lossis kab mob, muaj peev xwm loj hlob thiab kev tsim tawm".
Pom zoo:
Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Puas yog phages tshwj xeeb rau tus kab mob?
Bacteriophages, luv luv daim ntawv: phages (Greek: phagein = noj / nqos) yog cov kab mob nyob rau hauv lub dav biological kev nkag siab. Lawv tsuas yog tua cov kab mob thiab lyse lawv ("cov kab mob noj"). Phages tsis tuaj yeem tsim ib leeg los ntawm lawv tus kheej, lawv xav tau cov kab mob ntawm tes los ua tus tswv tsev kom rov tsim dua hauv tus tswv tsev
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
Cov kab mob puas yog ib hom kab mob ntawm tes?
Teb thiab piav qhia: Cov kab mob no tsis suav tias yog cov cell nyob thiab yog li ntawd tsis yog ib leeg-celled lossis ntau-celled. Lawv tsuas yog suav hais tias yog cov plhaub protein
Peb lub neej yog dab tsi thiab lawv cov yam ntxwv tshwj xeeb yog dab tsi?
Peb lub npe suav nrog: Archaea - cov npe qub tshaj plaws, cov kab mob qub. Cov kab mob - tag nrho lwm cov kab mob uas tsis suav nrog hauv Archaea domain. Eukarya - tag nrho cov kab mob uas muaj eukaryotic los yog muaj cov kab mob sib txuas thiab cov nuclei
