Qhov sib txawv tseem ceeb ntawm trichome thiab filament yog tias trichome yog cov plaub hau zoo li cov epidermal outgrowth pom ntawm cov nroj tsuag, thaum lub filament yog lub stalk ntawm paj stamens uas txhawb nqa anther.
Nroj tsuag muaj cov qauv sib txawv uas pab lawv sib txawv. Trichome thiab filament yog ob hom qauv uas muaj txiaj ntsig zoo. Trichome yog ib qho epidermal outgrowth pom ntawm cov nroj tsuag. Nyob rau hauv tas li ntawd, lub filament yog lub slender thiab elongated stalk ntawm stamens, uas bears anther nyob rau saum toj. Trichome tiv thaiv cov nroj tsuag los ntawm ntau yam kev puas tsuaj xws li UV teeb, kab, khov intolerance, transpiration, thiab lwm yam. Qee cov trichomes kuj zais qee qhov secretions tseem ceeb. Filament, ntawm qhov tod tes, nourishes lub anther thiaj li tsim pollens.
Trichome yog dab tsi?
Trichome yog ib qho kev loj hlob ntawm epidermal pom zoo li cov plaub hau me me ntawm cov nroj tsuag qia thiab ceg. Qhov tseeb, lawv zoo li cov nplai muaj nyob rau ntawm tsob ntoo qia. Trichomes feem ntau muab kev tiv thaiv rau cov nroj tsuag tiv thaiv UV teeb, kab, transpiration, thiab khov intolerance.
Daim duab 01: Trichome
Tej zaum yuav muaj ntau hom trichomes xws li cov plaub hau, caj dab plaub hau, nplai, thiab papillae, thiab lwm yam. Cov plaub hau ntau tshaj plaws. Cov plaub hau tuaj yeem yog unicellular lossis multicellular. Lawv tuaj yeem ua tau ceg lossis tsis muaj ceg. Qee qhov trichomes tuaj yeem yog qog. Glandular trichomes secretes secretions xws li metabolites, roj yam tseem ceeb, thiab lwm yam. Non-glandular trichomes tiv thaiv cov nroj tsuag los ntawm UV teeb.
Filament yog dab tsi?
Ib lub filament is the stalk of the stamens of a flower. Structurally, ib tug filament yog ib feem ntawm cov txiv neej lub cev xeeb tub hauv paj. Nws dais anther ntawm nws apex. Yog li ua ke nrog lub anther, filament ua rau cov txiv neej cov kab mob ntawm cov nroj tsuag. Nws yog ib tug elongated stalk. Pollens tsim nyob rau hauv lub anthers. Yog li ntawd, filament txhawb lub anther rau pollen ntau lawm. Nws thauj cov as-ham mus rau anther thiaj li tsim pollens. Ntxiv mus, pollinators nkag mus rau lub anthers nrog kev pab los ntawm filaments.
Daim duab 02: Filaments
Ib lub paj yuav muaj ob peb filaments. Thaum lub paj tawg paj, lub paj yuav ntev dua, thiab peb tuaj yeem pom lawv nyob rau hauv ib lub voj voog nyob ib ncig ntawm qhov nruab nrab ntawm lub paj. Hauv qee lub paj, filaments yog fused, thiab anthers yog dawb. Ntau fused filaments tuaj yeem tsim ib kem hu ua androphore. Tab sis, feem ntau cov paj, filaments yog dawb, thiab anthers yog fused. Lub filament yog tsau rau lub anther nyob rau hauv ob txoj kev: basifixed los yog dorsifixed.
Qhov Zoo sib xws ntawm Trichome thiab Filament yog dab tsi?
- Ob qho tib si trichome thiab filament yog ob lub qauv lossis qhov pom hauv cov nroj tsuag.
- Lawv yog cov qauv siv tau zoo ntawm cov nroj tsuag.
Qhov txawv ntawm Trichome thiab Filament yog dab tsi?
Ib trichome yog cov plaub hau zoo li epidermal outgrowth pom ntawm cov nroj tsuag, thaum lub filament yog lub slender thiab elongated stalk ntawm stamens. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm trichome thiab filament. Tsis tas li ntawd, trichome tiv thaiv cov nroj tsuag los ntawm UV teeb, kab, transpiration thiab freezes intolerance. Nyob rau tib lub sijhawm, cov filament txhawb nqa nws cov anther los ntawm kev muab cov as-ham thiab tuav nws rau pollinators. Yog li, qhov no kuj yog qhov sib txawv tseem ceeb ntawm trichome thiab filament.
Summary – Trichome vs Filament
Ob qho tib si trichome thiab filament yog cov qauv tsim nyog ntawm cov nroj tsuag. Trichome yog ib qho epidermal appendage, uas yog cov plaub hau zoo li cov qauv ntawm cov nroj tsuag. Meanwhile, lub filament yog stalk ntawm stamens uas tuav nws anther. Nws yog ib feem ntawm cov txiv neej reproductive lub cev ntawm cov nroj tsuag. Trichomes pom nyob rau hauv ntau hom nroj tsuag, tab sis ib tug filament yog tshwj xeeb rau flowering nroj tsuag vim nws pom nyob rau hauv lub paj. Yog li, qhov no qhia txog qhov sib txawv ntawm trichome thiab filament.
