Ib yam uas yog multicellular yog complex kab mob , ua los ntawm ntau lub hlwb. Tib neeg yog multicellular . Thaum ib leeg-celled kab mob tuaj yeem ' feem ntau tsis pom yam tsis muaj lub tshuab tsom iav, koj ua tau saib feem ntau multicelluar kab mob nrog lub qhov muag liab qab.
Ib yam li ntawd, uas yog ib qho kab mob multicellular?
Multicellular kab mob yog kab mob uas muaj ntau tshaj ib lub cell, sib piv rau unicellular kab mob.
Tsis tas li ntawd, 3 yam piv txwv ntawm cov kab mob ntau yam kab mob yog dab tsi? Piv txwv ntawm cov kab mob multicellular yog
- A. Algae, kab mob.
- B. Kab mob thiab fungi.
- C. Cov kab mob thiab kab mob.
- D. Algae thiab fungi.
Kuj tseem paub yog, dab tsi yog cov kab mob multicellular nrog piv txwv?
Tib neeg, tsiaj txhu, nroj tsuag kab yog cov piv txwv ntawm a multicellular kab mob . Cov no kab mob delegate biological luag hauj lwm xws li barrier muaj nuj nqi, digestion, ncig, ua pa thiab kev sib deev reproduction rau ib tug tej yam hauv nruab nrog cev xws li lub plawv, tawv nqaij, ntsws, plab, thiab kev sib deev organ.
Vim li cas tib neeg thiaj li muaj ntau yam kab mob?
Multicellular kab mob yog cov uas ua los ntawm ntau lub hlwb. Tib neeg yog multicellular . Qhov no yog vim lub hlwb ntawm cov kab mob tau tshwj xeeb rau hauv ntau hom hlwb xws li paj hlwb, cov qe ntshav, cov leeg hlwb txhua yam ua haujlwm sib txawv.
