Qhov sib txawv tseem ceeb ntawm pollination thiab fertilization yog tias pollination yog hais txog kev hloov paj ntoos ntawm anthers mus rau stigma ntawm paj thaum fertilization yog fusion ntawm txiv neej thiab poj niam gametes thiaj li tsim tau ib tug zygote. Pollination yog ua raws li fertilization nyob rau hauv flowering nroj tsuag.
Pollination thiab fertilization yog ob txoj hauv kev tsim cov xeeb ntxwv, txawm hais tias yav dhau los tsuas yog siv tau rau cov paj ntoo xwb thaum kawg siv tau rau yuav luag txhua yam kab mob hauv ntiaj teb no.
Pom paj yog dab tsi?
Pollination yog txheej txheem ntawm hloov paj ntoos los ntawm anthers mus rau stigma ntawm paj. Cov txheej txheem ntawm pollination tau pom tiag tiag hauv 18th xyoo pua los ntawm Christian Sprengel. Muaj ob hom pollination: self-pollination los yog cross-pollination. Self-pollination tshwm sim nyob rau hauv tib lub paj thaum cross-pollination tshwm sim ntawm ob lub paj ntawm txawv nroj tsuag.
Daim duab 01: pollination
Tus kheej-pollination tsim cov noob caj ces zoo tib yam thaum hla-pollination tsim cov noob caj noob ces. Yog li ntawd, cross-pollination yog nyiam tshaj li tus kheej-pollination. Nroj tsuag qhia kev hloov pauv sib txawv txhawm rau txhawm rau tiv thaiv tus kheej pollination thiab txhim kho cross-pollination. Thaum pollination tshwm sim, cov phev cell mus rau lub qe cell thiab fertilization tshwm sim. Qhov no ua kom tiav kev sib deev ntawm cov paj ntoo.
Fertilization yog dab tsi?
Fertilization yog kev sib koom ua ke ntawm txiv neej thiab poj niam gametes txhawm rau tsim cov xeeb ntxwv. Tus poj niam lub qe yuav fertilized los ntawm ib tug txiv neej phev thiab qhov no yuav ua rau tsim ib tug me nyuam, tsis yog rau tsiaj los yog nroj tsuag.
Daim duab 02: Fertilization
Rau paj, qhov no tsuas yog tshwm sim tom qab ua tiav pollination thiab thaum muaj kev vam meej fusion ntawm txiv neej thiab poj niam gametes. Noob yog tshwm sim ntawm fertilization ntawm cov nroj tsuag. Cov noob ces ua rau cov nroj tsuag tshiab. Fertilization yog txheej txheem sab hauv, tsis zoo li pollination.
Dab tsi zoo sib xws ntawm pollination thiab Fertilization?
- Ob qho tib si pollination thiab fertilization tshwm sim nyob rau hauv flowering nroj tsuag.
- Lawv yog cov txheej txheem tseem ceeb heev nrog rau kev tsim tawm.
Qhov txawv ntawm pollination thiab Fertilization yog dab tsi?
Pollination yog kev hloov ntawm paj ntoos los ntawm anthers rau stigma ntawm paj thaum fertilization yog fusion ntawm txiv neej thiab poj niam gametes hauv kev sib deev. Qhov tseem ceeb tshaj plaws, pollination tsuas yog siv tau rau cov paj ntoo thaum fertilization muaj feem xyuam rau yuav luag txhua yam kab mob nyob hauv lub ntiaj teb no. Nyob rau hauv flowering nroj tsuag, fertilization yog tus txheej txheem ua raws li pollination.
Tsis tas li ntawd, pollination tuaj yeem yog txheej txheem sab nraud thaum fertilization yog ib qho txheej txheem sab hauv. Ntxiv mus, pollination, epically cross-pollination yuav tsum tau pollinators whereas fertilization tsis xav tau pollinators.
Summary – Pollination vs Fertilization
Pollination tsuas yog cov txheej txheem ntawm kev hloov cov paj ntoos mus rau qhov qias neeg. Qhov no tuaj yeem ua tiav los ntawm tus kheej-pollination lossis cross-pollination. Hla-pollination yog thaum muaj cov neeg sawv cev sab nraud xws li tsiaj txhu, tib neeg lossis cua, los pab txhawb kev hloov ntawm paj ntoos mus rau stigma. Thaum pollination tsuas yog siv rau cov paj ntoo, fertilization siv rau yuav luag txhua tus neeg hauv qhov xwm txheej. Qhov tseem ceeb tshaj plaws, yuav tsis muaj fertilization yog tias tsis muaj pollination. Qhov no yog qhov txawv ntawm pollination thiab fertilization.
