Qhov sib txawv tseem ceeb ntawm bryophytes thiab tracheophytes yog tias bryophytes yog cov nroj tsuag uas tsis muaj hlab ntsha; Yog li ntawd, tsis txhob muaj cov kab mob vascular thaum tracheophytes yog cov nroj tsuag vascular, yog li muaj cov kab mob vascular zoo.
Nroj tsuag yog cov kab mob uas tsis yog-motile eukaryotic uas tshwm hauv cov xim ntsuab. Lawv yog photoautotrophs uas tsim cov khoom noj los ntawm photosynthesis. Cov nroj tsuag belongs rau Kingdom Plantae. Kingdom Plantae muaj ob pawg tseem ceeb ntawm cov nroj tsuag raws li qhov muaj thiab tsis muaj vascular system. Lawv yog cov nroj tsuag tsis-vascular lossis bryophytes thiab vascular nroj tsuag lossis tracheophytes. Bryophytes thiab tracheophytes txawv ntawm ib leeg los ntawm ntau yam ntxwv raws li tau hais hauv kab lus no.
YBryophytes yog dab tsi?
Bryophytes yog cov nroj tsuag keeb kwm av. Structurally, lawv yog cov nroj tsuag uas tsis yog vascular. Yog li lawv tsis muaj vascular system. Tsis tas li ntawd, lawv yog cov nroj tsuag me me uas nyob hauv qhov chaw moist thiab shady. Lwm tus yam ntxwv tseem ceeb ntawm bryophytes yog kev hloov ntawm tiam. Lawv lub cim tseem ceeb yog tiam haploid gametophytic. Yog li ntawd, lawv tiam sporophytic tsis tshua muaj meej.
Daim duab 01: Bryophytes – Mosses
Tsis tas li ntawd, bryophytes tsis muaj lub cev cog sib txawv. Yog li ntawd, lawv tsis muaj cov cag, qia thiab nplooj. Lawv lub cev cog feem ntau yog nplooj los yog thalloid. Hloov cov hauv paus hniav, lawv muaj cov hauv paus zoo li cov qauv hu ua rhizoids rau qhov txuas. Txij li thaum lawv tsis muaj vascular system, lawv nqus dej los ntawm nplooj. Bryophytes tsim kev sib deev los ntawm kev tsim archegonia thiab antheridia. Muaj peb hom nroj tsuag tuaj hauv qab bryophytes xws li mosses, liverworts thiab hornwort.
YDab tsi yog Tracheophytes?
Tracheophytes yog cov nroj tsuag vascular av uas muaj cov kab mob vascular zoo (xylem thiab phloem). Tsis tas li ntawd, tracheophytes muaj cov nroj tsuag sib txawv. Yog li ntawd, lawv muaj cov hauv paus hniav, qia thiab nplooj. Raws li txoj cai, tracheophytes yog cov nroj tsuag loj dua hloov mus rau qhov sib txawv ib puag ncig, tsis zoo li bryophytes. Lawv muaj stomata thiab tuab tuab waxy cuticle los tswj thiab tiv thaiv dej poob raws.
Daim duab 02: Tracheophytes – Fern
Qee tracheophytes rov tsim dua los ntawm cov noob thaum qee cov tracheophytes rov tsim dua los ntawm spores. Lwm tus cwj pwm tseem ceeb ntawm tracheophytes yog qhov tseem ceeb sporophyte tiam. Lawv lub cim gametophytic tsis tshua muaj. Ferns, horsetails, angiosperms thiab gymnosperms belongs rau cov nroj tsuag no.
Dab tsi yog qhov zoo sib xws ntawm Bryophytes thiab Tracheophytes?
- Bryophytes thiab Tracheophytes yog ob pawg nroj tsuag uas zwm rau Kingdom Plantae.
- Lawv yog multicellular eukaryotes.
- Tsis tas li, ob leeg muaj xim ntsuab yog li lawv muaj peev xwm ntawm photosynthesizing.
- Ntxiv mus, ob qho tib si yog photoautotrophs.
- Tsis tas li ntawd, lawv yog cov kab mob tsis muaj zog.
- Thiab, ob leeg yug los ntawm kev sib deev thiab kev sib deev.
Qhov txawv ntawm Bryophytes thiab Tracheophytes yog dab tsi?
Bryophytes yog cov nroj tsuag tsis-vascular thaj av txwv rau qhov chaw ntub dej thiab ntxoov ntxoo thaum tracheophytes yog cov nroj tsuag av vascular hloov mus rau qhov sib txawv ib puag ncig. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm bryophytes thiab tracheophytes. Tsis tas li ntawd, qhov sib txawv tseem ceeb ntawm bryophytes thiab tracheophytes yog tias bryophytes feem ntau yog nplooj los yog thalloid thiab cov nroj tsuag me me thaum tracheophytes yog cov nroj tsuag loj sib txawv.
Lwm qhov txawv ntawm bryophytes thiab tracheophytes yog tias bryophytes muaj lub cim gametophytic tseem ceeb thaum tracheophytes muaj lub cim tseem ceeb sporophyte. Mosses, liverworts thiab hornworts yog bryophytes thaum ferns, gymnosperms thiab angiosperms yog tracheophytes.
Summary – Bryophytes vs Tracheophytes
Cov nroj tsuag uas tsis yog vascular lossis bryophytes tsis muaj cov hlab ntsha. Yog li ntawd, lawv yog cov nroj tsuag me me uas txwv rau qhov chaw noo thiab shady ib puag ncig. Ntawm qhov tod tes, cov nroj tsuag vascular lossis tracheophytes muaj cov kab mob vascular zoo uas suav nrog xylem thiab phloem. Yog li ntawd, lawv nyob hauv ntau qhov chaw. Ntxiv mus, lawv yog cov nroj tsuag siab dua xws li angiosperms thiab gymnosperms. Hauv qhov sib piv, bryophytes yog cov nroj tsuag qub xws li mosses, liverworts thiab hornworts. Qhov no yog qhov txawv ntawm bryophytes thiab tracheophytes.
