Qhov sib txawv ntawm tsob ntoo thiab tsob ntoo yog tsob ntoo yog tsob ntoo uas muaj xyoob ntoo uas muaj lub cev ncaj tsis ncaj thaum cov nroj tsuag yog tswv cuab ntawm lub nceeg vaj Plantae.

Kingdom Plantae yog ib qho ntawm tsib lub nceeg vaj ntawm cov kab mob uas muaj sia nyob uas suav nrog photosynthetic, immobile ntsuab xim multicellular eukaryotes. Lawv yog photoautotrophs. Lawv tsim lawv tus kheej cov zaub mov los ntawm cov pa roj carbon inorganic los ntawm kev tau txais lub zog los ntawm lub hnub ci. Muaj ntau pawg ntawm cov nroj tsuag. Ntawm lawv, ntoo yog cov nroj tsuag loj dua uas muaj lub cev. Txawm hais tias tag nrho cov tswv cuab ntawm lub nceeg vaj Plantae hais txog cov nroj tsuag, cov npe tshwj xeeb xws li ntoo, tsob ntoo, thiab lwm yam.kuj siv los categorize nroj tsuag. Lub hom phiaj ntawm tsab xov xwm no yog los piav qhia qhov txawv ntawm tsob ntoo thiab tsob nroj.

tsob ntoo yog dab tsi?

tsob ntoo yog tsob ntoo uas muaj xyoob ntoo, uas muaj ntau cov ceg ntoo thib ob ntawm lub cev (stem) nrog qhov tseeb apical dominance. Thaum loj hlob theem, qhov siab yam tsawg kawg nkaus yog 3m, thiab qhov tsawg kawg nkaus ib ncig yog 30cm. Shrubs yog cov ntoo ntoo, uas tsis tuaj yeem ua tau raws li cov kev xav tau hais saum toj no. Feem ntau ntawm cov ntoo yog paj ntoo (Angiosperms) thiab conifers. Muaj txog 100, 000 hom ntoo hauv ntiaj teb, thiab nws yog li 25% ntawm tag nrho cov nroj tsuag. Feem ntau ntawm cov ntoo muaj nyob rau hauv cheeb tsam tropical.

Daim duab 01: Tsob Ntoo

Cov ntoo ntxov tshaj plaws yog tsob ntoo ferns uas hloov zuj zus ntawm lub sijhawm Carboniferous. Ib tsob ntoo muaj qhov sib txawv loj xws li hauv paus, qia, ceg, twigs, thiab nplooj, thiab lwm yam. Woody ib feem ntawm tsob ntoo muaj cov ntaub so ntswg xylem thaum cov tawv ntoo muaj phloem cov ntaub so ntswg. Lub hav zoov los yog copse yog ib pawg me me ntawm cov ntoo thaum lub hav zoov yog ib qho toj roob hauv pes uas npog los ntawm ib pawg ntoo loj. Kev tsim cov ntoo yog qhov tseem ceeb ntawm kev siv ntoo. Tsis tas li ntawd, lawv muab zaub mov, taws, tshuaj thiab lwm yam.

tsob nroj yog dab tsi?

Lo lus cog muaj ob lub ntsiab lus sib txawv; nws txhais tau tias ib tug tswv cuab ntawm Kingdom Plantae. Qhov thib ob, nws tuaj yeem siv dav los xa cov tswv cuab ntawm Kingdom Plantae uas me dua cov ntoo lossis tsob ntoo. Cov pab pawg ntawm cov nroj tsuag muaj xws li Bryophytes, Ferns, Conifers, thiab flowering nroj tsuag.

Ntxiv mus, cov nroj tsuag yog autotrophic eukaryotes, uas tau yoog rau lub neej hauv thaj av. Lub hauv paus ntawm lub zog ntawm cov nroj tsuag yog hnub ci, thiab lawv tuaj yeem tsim cov khoom noj los ntawm cov khoom siv tsis zoo ntawm cov pa roj carbon. Yog li ntawd, lawv yog cov kab mob photoautotrophic. Photosynthesis yog cov txheej txheem uas lawv ua los tsim lawv tus kheej cov zaub mov. Muaj txog 315,000 ntawm cov nroj tsuag uas tuaj yeem pom, thiab tawm ntawm qhov ntawd, nyob ib ncig ntawm 85% yog cov paj ntoo. Cov nroj tsuag tseem ceeb heev vim lawv muab zaub mov, tshuaj, muaj txiaj ntsig zoo nkauj thiab kev xav tau ntawm kev tshawb fawb thiab kab lis kev cai, thiab lwm yam.

  • Tsob ntoo thiab tsob ntoo belongs rau lub nceeg vaj Plantae.
  • Lawv yog multicellular eukaryotes.
  • Tsis tas li ntawd, lawv yog cov kab mob photosynthetic. Li no, lawv yog photoautotrophs.
  • Kuj, ob leeg tshwm hauv xim ntsuab.
  • Ntxiv mus, ob qho tib si muaj chloroplasts thiab chlorophylls.
  • Lawv yog cov kab mob tsis txav chaw.
  • Ob tsob ntoo thiab tsob ntoo yog yoog rau lub neej ntawm thaj av.

Txiv ntoo thiab tsob ntoo yog dab tsi?

tsob ntoo yog tsob ntoo muaj xyoob ntoo uas muaj lub cev ncaj. Yog li ntawd, ntoo yog ib pawg ntawm cov nroj tsuag. Ntawm qhov tod tes, ib tsob nroj yog ib tug tswv cuab ntawm lub nceeg vaj Plantae. Yog li ntawd, qhov no yog qhov sib txawv tseem ceeb ntawm tsob ntoo thiab tsob ntoo. Tsis tas li ntawd, ntau haiv neeg ntawm cov nroj tsuag yog sib piv siab dua cov ntoo. Yog li, nws yog lwm qhov sib txawv ntawm tsob ntoo thiab tsob ntoo. Tsis tas li ntawd, tsob ntoo yeej ib txwm muaj ib lub cev ntoo thaum cov nroj tsuag tuaj yeem muaj cov kab ntoo, cov stems los yog pseudostem, thiab ib qia los yog ntau cov qauv qia. Yog li, qhov no yog lwm qhov sib txawv ntawm tsob ntoo thiab tsob ntoo.

Feem ntau, cov ntoo muaj rau conifers lossis paj paj pawg, thiab lawv yog autotrophic. Tab sis qee cov nroj tsuag yog heterotrophic. Cuscuta yog ib qho piv txwv rau cov nroj tsuag heterotrophic. Nroj tsuag loj hlob thoob plaws cheeb tsam ntawm lub ntiaj teb no. Tab sis cov ntoo tsuas yog loj hlob nyob rau hauv cheeb tsam tropical.

Tsis tas li ntawd, cov nroj tsuag tuaj yeem yog tsob ntoo, moss, fern, ntoo, thiab lwm yam. Tab sis, tsob ntoo belongs rau ib pawg ntawm cov nroj tsuag. Li no, piv rau cov ntoo, cov nroj tsuag muaj ntau haiv neeg. Tag nrho cov ntoo yog photosynthetic li no photoautotrophs, thaum qee cov nroj tsuag yog heterotrophic. Yog li, qhov no yog qhov txawv ntawm tsob ntoo thiab tsob ntoo.
