Qhov sib txawv tseem ceeb ntawm monocolpate thiab tricolpate yog tias monocolpate pollens muaj ib qho furrow ntawm ib sab thaum tricolpate pollens muaj peb meridionally tso furrows. Lwm qhov sib txawv tseem ceeb ntawm monocolpate thiab tricolpate yog tias monocolpate pollens yog yam ntxwv rau monocotyledons thaum tricolpate pollens yog yam ntxwv rau dicotyledons.
Pollen nplej yog txiv neej microgametophytes ntawm cov noob nroj tsuag. Lawv tsim txiv neej gametes lossis phev. Colpus yog ib qho aperture nyob rau hauv paj paj noob hlis ntawm angiosperms. Nws yog ib tug ntev furrow-zoo li aperture. Cov paj ntoos uas muaj xws li apertures (colpi) yog hu ua colpate pollens. Hauv angiosperms, muaj ob hom colpate pollen nplej. Lawv yog monocolpate pollen nplej thiab tricolpate pollens nplej. Monocolpate pollens tsuas muaj ib qho furrow ntawm ib sab. Tricolpate pollens muaj peb meridionally tso furrows. Nyob rau hauv cov xwm, monocot nroj tsuag dais monocolpate pollens thaum dicot nroj tsuag muaj tricolpate pollens.
Monocolpate yog dab tsi?
Monocolpate pollens yog paj ntoos nplej uas muaj ib qho furrow ntawm ib sab. Cov paj ntoo no yog cov yam ntxwv ntawm cov nroj tsuag monocot. Cov nroj tsuag uas muaj nyob rau Liliaceae, Arecaceae, Asparagaceae thiab Ginkgoaceae muaj cov kab mob monocolpate. Yog li ntawd, cycads thiab Ginko feem ntau tsim cov paj ntoo monocolpate. Lawv muaj ib tug tsis tu ncua thiab paub colpus nyob rau hauv lawv pollens. Feem ntau, monocolpate pollens muaj qhov ntev tshaj plaws ntawm 40 micrometers lossis tsawg dua. Txawm li cas los xij, muaj cov paj ntoo monocolpate uas muaj qhov ntev tshaj 40 micrometers.

Tricolpate yog dab tsi?
Pollen nplej uas muaj peb lub furrows hu ua tricolpate pollens. Feem ntau cov nroj tsuag dicot dais tricolpate pollens. Txawm li cas los xij, tsis yog txhua tus dicots muaj tricolpate pollens. Vim cov colpi no, tricolpate pollens muaj cov duab. Tsev neeg Acanthaceae muaj cov yam ntxwv ntawm tricolpate pollens. Cerocarpus ledifolius, uas belongs rau tsev neeg Rosaceae, thiab Quercus agrifolia, uas belongs rau tsev neeg Fagaceae tsim tricolpate pollens.

Eudicots kuj tau hu ua tricolpates ua ntej. Muaj peb lub colpi paralleling lub polar axis ntawm paj ntoos yog qhov txawv ntawm qhov tseeb dicotyledons.
Dab tsi yog qhov zoo sib xws ntawm Monocolpate thiab Tricolpate?
- Monocolpate amd tricolpate yog ob hom colpate pollen nplej.
- Monocolpate thiab tricolpate pollen nplej yog yam ntxwv rau angiosperms.
- Lawv muaj elongated furrows nyob rau hauv lawv pollen nplej.
Qhov txawv ntawm Monocolpate thiab Tricolpate yog dab tsi?
Monocolpate thiab tricolpate yog ob pawg tseem ceeb ntawm paj ntoos pom nyob rau hauv angiosperms. Monocolpate pollens tsuas muaj ib qho ntev ntev thaum tricolpate pollens muaj peb qhov ntev ntev. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm monocolpate thiab tricolpate. Qhov tseeb, cov paj ntoo monocolpate raug pom nyob rau hauv monocotyledons thaum cov paj ntoos tricolpate feem ntau pom hauv cov nroj tsuag dicotyledon.
Ntxiv mus, sib nrug los ntawm monocolpate, trichomocolpate, thiab tshwj xeeb inaperturate, yog ob hom apertural hom monocolpate thaum colpate, colporate, porate thiab pororate yog apertural hom tricolpate.
Cov infographic hauv qab no qhia txog qhov sib txawv ntawm monocolpate thiab tricolpate pollen nplej.
Summary – Monocolpate vs Tricolpate
Colpus yog ib qho elongated aperture pom nyob rau hauv paj ntoos nplej. Qee cov paj ntoos muaj tsuas yog ib qho colpus thaum qee cov paj ntoos muaj ntau tshaj ib colpus. Cov paj ntoos uas muaj ib lub furrow hu ua monocolpate pollens, thiab lawv muaj nyob rau hauv cov nroj tsuag monocot. Cov paj ntoos uas muaj peb lub furrows yog hu ua tricolpate pollen nplej, thiab lawv muaj nyob rau hauv feem ntau cov nroj tsuag dicot. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm monocolpate thiab tricolpate.
