Qhov sib txawv tseem ceeb ntawm mosses thiab ferns yog tias mosses yog cov kab me me uas tsim cov nroj tsuag uas tsis muaj kab mob, thaum ferns yog cov nroj tsuag tsim cov kab mob vascular.
Ntau ntau hom nroj tsuag nyob rau hauv peb ib puag ncig. Qee cov nroj tsuag yog ntoo thaum qee cov tshuaj ntsuab, bushes, creepers, thiab lwm yam. Yog tias peb xav paub txog cov nroj tsuag thiab lawv cov yam ntxwv, nws yog ib qho tsim nyog yuav tsum nkag siab txog kev faib cov nroj tsuag. Kingdom Plantae yog ib qho ntawm tsib lub nceeg vaj ntawm Whittaker qhov kev faib tawm. Kingdom Plantae tuaj yeem muab faib ua Thallophyta, Bryophyta, Pteridophyta, Gymnosperms thiab Angiosperms los ntawm kev xav txog lawv cov yam ntxwv tshwj xeeb thiab tshwj xeeb. Bryophytes yog cov nroj tsuag me me uas tsis muaj vascular loj hlob hauv qhov chaw noo thiab ntxoov ntxoo. Mosses thiab liverworts yog bryophytes. Pteridophytes yog thawj cov nroj tsuag vascular. Ferns belongs rau Pteridophyta. Ob lub mosses thiab ferns tsis tsim noob lossis paj. Ntxiv mus, ob qho tib si mosses thiab ferns yog cov nroj tsuag qub, tsis zoo li gymnosperms thiab angiosperms.
Mosses yog dab tsi?
Mosses yog bryophytes; Cov nroj tsuag me me uas tsis yog vascular thiab zoo li lichens. Lawv yog cov nroj tsuag primitive uas loj hlob hauv qhov chaw ntub dej thiab shady. Tsis tas li ntawd, lawv yog cov nroj tsuag photosynthetic, thiab muaj ntau ntau hom moss (tsawg kawg 12,000 hom).
Hais txog lawv kev yug me nyuam, mosses reproduces ntawm spores, thiab lawv xav tau dej rau kev yug me nyuam. Lawv tsis tsim noob lossis paj. Tsis tas li ntawd, mosses qhia alternation ntawm tiam. Qhov tseem ceeb theem yog gametophyte tiam. Tsis tas li ntawd, lawv tsis muaj tseeb stems, nplooj los yog cag. Tab sis, lawv muaj rhizoids es tsis yog cov hauv paus hniav.
Daim duab 01: Mosses
Mosses ua lub luag haujlwm tseem ceeb hauv kev tswj hwm ecosystems. Lawv muab cov txheej txheem tsis tseem ceeb rau lwm cov nroj tsuag. Lawv kuj yog qhov qhia tau zoo heev ntawm thaj chaw zoo. Ntxiv mus, lawv tuaj yeem tswj cov av noo. Ntxiv rau qhov ntawd, lawv pab rov ua dua cov khoom noj hauv hav zoov.
Ferns yog dab tsi?
Ferns yog cov nroj tsuag vascular teej tug mus rau pawg Pteridophyta. Tab sis, tsis zoo li lwm cov nroj tsuag vascular, ferns tsis tsim noob lossis paj. Ferns tsim spores thiaj li yuav yug me nyuam. Ferns muaj tseeb stems, nplooj thiab keeb kwm. Ntxiv mus, lawv qhia alternation ntawm tiam. Tab sis qhov tseem ceeb theem ntawm lub neej voj voog yog lub tiam diploid sporophyte. Gametophyte yog ib tug prothallus uas yog dawb-nyob, multicellular thiab photosynthetic. Qee cov ferns muaj saum toj-hauv av erect semi-woody trunks thaum qee cov ferns muaj saum av creeping stolons. Ib qho tshwj xeeb ntawm ferns yog tias lawv qhia circinate vernation.
Daim duab 02: Ferns
Ferns yog zus raws li cov nroj tsuag ornamental nyob rau hauv domestic ib puag ncig. Lawv kuj muaj txiaj ntsig zoo li tshuaj, biofertilizers thiab kho cov kab mob sib kis.
Qhov Zoo sib xws ntawm Mosses thiab Ferns yog dab tsi?
- Ob lub mosses thiab ferns yog cov nroj tsuag nrog keeb kwm keeb kwm.
- Lawv tsim spores hloov cov noob.
- Lawv loj hlob zoo nyob rau hauv qhov chaw noo, shady.
- Ntau mosses thiab ferns tuaj yeem loj hlob rau lwm cov nroj tsuag xws li ntoo.
- Ob leeg mosses thiab ferns qhia alternation ntawm tiam.
- Lawv nyob ntawm dej rau kev yug me nyuam.
- Lawv tsis tsim paj thiab.
Qhov txawv ntawm Mosses thiab Ferns yog dab tsi?
Mosses yog cov nroj tsuag me me uas tsis muaj kab mob hauv av, thaum ferns yog thawj cov nroj tsuag hauv av. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm mosses thiab ferns. Mosses belongs rau phylum Bryophyta, thaum ferns belongs rau phylum Pteridophyta.
Ntxiv mus, mosses tsis qhia qhov sib txawv ntawm cov nroj tsuag lub cev, thaum ferns qhia qhov sib txawv uas muaj tseeb stems, nplooj thiab cov hauv paus hniav nyob rau hauv cov nroj tsuag lub cev. Tsis tas li ntawd, ob qho tib si mosses thiab ferns qhia alternation ntawm tiam. Tab sis, cov theem tseem ceeb ntawm lub neej voj voog ntawm mosses yog tiam haploid gametophyte, thaum lub sij hawm tseem ceeb ntawm lub neej voj voog ntawm ferns yog tiam diploid sporophyte. Yog li ntawd, qhov no yog lwm qhov sib txawv tseem ceeb ntawm mosses thiab ferns.
Cov duab hauv qab no qhia txog qhov sib txawv ntawm mosses thiab ferns.
Summary – Mosses vs Ferns
Mosses yog cov kab me me uas tsim cov nroj tsuag uas tsis yog hlab ntsha, thaum ferns yog cov nroj tsuag vascular. Tsis tas li ntawd, mosses tsis muaj tseeb stems, nplooj thiab cov hauv paus hniav, thaum ferns muaj ib tug txawv nroj tsuag lub cev rau hauv tseeb qia, nplooj thiab keeb kwm. Tsis tas li ntawd, ferns qhia circinate vernation, tsis zoo li mosses. Tsis tas li ntawd, gametophyte yog lub cim tseem ceeb hauv mosses, thaum sporophyte yog lub cim tseem ceeb hauv ferns.
