Qhov sib txawv tseem ceeb ntawm eudicots thiab monocots yog tias eudicots yog cov nroj tsuag dicot uas muaj peb lub furrows lossis pores (tricolpate) hauv lawv cov paj ntoos thaum monocots yog cov nroj tsuag uas muaj ib qhov pore lossis furrow (monosulcates) hauv lawv cov paj ntoos..
Paj paj lossis angiosperms yog cov nroj tsuag uas tsim paj kom ua tiav kev sib deev. Muaj ob pawg tseem ceeb ntawm angiosperms li eudicotyledons (eudicots) thiab monocotyledons (monocots). Eudicotyledons muaj ob lub cotyledons thaum monocotyledons lossis monocots tsuas muaj ib cotyledon xwb. Ntxiv mus, eudicots muaj peb qhov pores hauv lawv cov paj ntoos thaum monocots tsuas muaj ib qhov pore hauv lawv cov paj ntoos.
Eudicots yog dab tsi?
Eudicots yog pawg loj tshaj plaws ntawm cov paj ntoo thiab suav nrog li peb feem peb ntawm cov paj ntoo. Lawv kuj tseem hu ua tricolpates cov nroj tsuag vim lawv muaj peb lub apertures lossis pores hauv lawv cov paj ntoos. Yog li ntawd, lawv dais tricolpate pollens, tsis zoo li monocots. Ntxiv mus, eudicots tsim ob cotyledons thaum lawv cov noob germinate. Tsis tas li ntawd, eudicots qhia kev loj hlob theem nrab. Lawv nplooj muaj ib tug netlike venation qauv. Qhov tseem ceeb tshaj plaws, lawv cov paj muaj plaub lossis tsib qhov paj. Lwm qhov tshwj xeeb ntawm eudicots yog tias lawv cov khoom sieve muaj plastids uas muaj cov hmoov txhuv nplej siab. Ntxiv rau cov no, eudicots muaj lub hauv paus kais, tsis zoo li monocots.
Daim duab 01: Eudicots
Ntau tsev neeg eudicot yog buxaceae, didymelaceae, ceratophyllaceae, nelumbonaceae, platanaceae, proteaceae, sabiaceae, berberidaceae, circaeasteraceae, eupteleaceae, thiab trochodendraceae.
Monocots yog dab tsi?
Zoo ib yam li eudicots, monocots kuj yog ib pawg ntawm angiosperms. Txawm li cas los xij, lawv suav txog tsuas yog ib feem peb ntawm cov paj ntoo. Lawv tsuas muaj ib qho aperture hauv lawv cov paj ntoos. Tsis tas li ntawd, lawv tsim ib cotyledon nyob rau hauv yub thaum lub sij hawm noob germination. Lawv cov paj yog ntau yam ntawm peb. Cov nplooj Monocot qhia ib qho piv txwv venation qauv thiab lawv cov nplooj tsis qhia qhov sib txawv rau hauv nplooj nplooj thiab petiole. Hauv ntu ntu ntawm cov qia, cov kab mob vascular tau tawg.
Daim duab 02: Monocots
Monocot cov tsev neeg muaj xws li poaceae (cov nyom tiag), orchidaceae (orchids), liliaceae (lilies), arecaceae (palms), musaceae, zingiberaceae, asparagaceae, bromeliaceae, cyperaceae thiab iridaceae (irises).
Dab tsi yog qhov zoo sib xws ntawm Eudicots thiab Monocots?
- Eudicots thiab monocots yog ob pawg zoo ntawm cov paj ntoo lossis angiosperms.
- Lawv yog pawg monophyletic.
- Ntxiv mus, lawv tsim paj thiab noob.
Qhov txawv ntawm Eudicots thiab Monocots yog dab tsi?
Eudicots tsim cov paj ntoo tricolpate nrog peb lub qhov hws thaum monocots tsim cov paj ntoo monosulcate nrog ib lub qhov pore. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm eudicots thiab monocots. Ntxiv mus, eudicots tsim ob cotyledons hauv lawv cov yub thaum monocots tsim ib cotyledon hauv lawv cov yub. Yog li ntawd, peb tuaj yeem xav txog qhov no yog qhov sib txawv tseem ceeb ntawm eudicots thiab monocots.
Tsis tas li ntawd, cov paj ntawm eudicots yog plaub lossis tsib thaum paj ntawm monocots yog ntau ntawm peb. Tsis tas li ntawd, venation yog lwm qhov sib txawv ntawm eudicots thiab monocots. Reticulate venation qauv tuaj yeem pom nyob rau hauv nplooj ntawm eudicots thaum cov qauv venation sib npaug tuaj yeem pom ntawm nplooj ntawm monocots.
Cov hauv qab no qhia txog qhov sib txawv ntawm eudicots thiab monocots.
Summary – Eudicots vs Monocots
Eudicots account rau peb-quarters ntawm flowering nroj tsuag thaum monocots account rau ib feem peb ntawm flowering nroj tsuag. Qhov sib txawv tseem ceeb ntawm eudicot thiab monocots yog nyob ntawm tus naj npawb ntawm apertures hauv lawv cov paj ntoos. Eudicots muaj peb qhov apertures hauv paj ntoos thaum monocots muaj ib qho aperture hauv paj ntoos. Ntxiv mus, eudicots tsim ob cotyledons hauv lawv cov yub thaum monocots tsim ib cotyledon hauv lawv cov yub. Tsis tas li ntawd, eudicots muaj plaub lossis tsib qhov paj thaum monocots muaj ntau ntawm peb qhov paj.
