Roots ntawm cov nroj tsuag txav mus rau hauv dej, yog li lawv pom zoo hydrotropism. Thaum cov nroj tsuag qhia txog kev txav mus los hauv kev teb rau qhov kov ntawm ib qho khoom, nws hu ua thigmotropism.
Dab tsi ntawm cov nroj tsuag pom zoo phototropism?
Cov kab mob sib txawv ntawm cov nroj tsuag tuaj yeem pom qhov sib txawv ntawm cov duab phototropic rau qhov sib txawv wavelengths ntawm lub teeb. Stem lus qhia pom qhov zoo phototropic tshwm sim rau lub teeb xiav, thaum cov lus qhia hauv paus pom qhov tsis zoo phototropic cuam tshuam rau lub teeb xiav. Ob lub hauv paus cov lus qhia thiab cov lus qhia qia feem ntau pom zoo phototropism rau lub teeb liab.
Cov nroj tsuag twg teb qhov zoo?
Nyob rau hauv cov nroj tsuag, cov lus teb dav dav rau lub ntiajteb txawj nqus yog paub zoo: lawv roots teb zoo, loj hlob, mus rau hauv av, thiab lawv stems teb tsis zoo, loj hlob nce mus txog. tshav ntuj.
4 hom tropism yog dab tsi?
Cov ntaub ntawv ntawm tropism suav nrog phototropism (teb rau lub teeb), geotropism (teb rau lub ntiajteb txawj nqus), chemotropism (teb rau cov tshuaj tshwj xeeb), hydrotropism (teb rau dej), thigmotropism(teb rau mechanical stimulation), traumatotropism (teb rau qhov txhab txhab), thiab galvanotropism, los yog electrotropism (teb …
Peb hom tropism yog dab tsi?
Topisms yog kev loj hlob mus rau lossis deb ntawm kev txhawb nqa. Hom tropisms suav nrog gravitropism (lub ntiajteb txawj nqus), phototropism (lub teeb), thiab thigmotropism (kov).

Thaum twg cov ntaub so ntswg meristematic pom hauv cov nroj tsuag?
Meristematic cov ntaub so ntswg muaj nyob rau hauv ntau qhov chaw, suav nrog ze rau cov lus qhia ntawm cov hauv paus hniav thiab stems (apical meristems), nyob rau hauv lub buds thiab nodes ntawm stems, nyob rau hauv lub cambium ntawm lub xylem thiab phloem nyob rau hauv cov ntoo dicotyledonous thiab shrubs, nyob rau hauv lub epidermis ntawm dicotyledonous ntoo thiab shrubs (cork cambium), thiab nyob rau hauv pericycle ntawm … Vim li cas cov ntaub so ntswg meristematic
Koj yuav pom qhov twg ntau tshaj plaws ntawm cov hlwb tsis sib xws hauv cov nroj tsuag?
Cov qia hlwb yog cov hlwb tsis sib xws nyob hauv cov meristems ntawm cov nroj tsuag . Cov hlwb tsis sib txawv nyob qhov twg hauv cov nroj tsuag? Cov qia hlwb yog innately undifferentiated hlwb nyob rau hauv the meristems ntawm cov nroj tsuag.
Qhov twg ntawm cov nroj tsuag luam yeeb kis los ntawm meloidogyne incognita?
- Meloidogyne incognita kis cov cag ntawm cov nroj tsuag luam yeeb. Cog-parasitic nematodes los ntawm genus Meloidogyne yog cov hauv paus-knot nematodes . Yuav ua li cas cog cov luam yeeb? Cov nplooj tuaj yeem qhuav thiab zom ua tshuaj lom.
Dab tsi ntawm cov hauv qab no yog qhov dav dav ntawm kev sib cuam tshuam ntawm cov nroj tsuag-pollinator?
Teb yog A. Tight one to one co-evolutionary partnership. Cog pollinator kev sib cuam tshuam tau pab ob qho tib si pollinator thiab cov nroj tsuag hloov kho lawv lub cev yam ntxwv kom lawv tuaj yeem cuam tshuam tau zoo los txhawb kev tshwj xeeb ntawm lawv cov kev sib cuam tshuam .
Nitrification los ntawm cov kab mob zoo li cas rau cov nroj tsuag?
Nitrification los ntawm cov kab mob zoo li cas rau cov nroj tsuag? ib. Nws ua cov nitrates rau cov nroj tsuag siv. … Nws tsim cov roj nitrogen rau cog siv . Vim li cas nitrification tseem ceeb rau cov nroj tsuag? Nitrification yog ib qho tseem ceeb heev ntawm lub voj voog nitrogen, vim tias feem ntau cov nroj tsuag nitrate yog cov tshuaj lom neeg nyiam ntawm nitrogen uptake los ntawm av lossis dej Nitrification yog ob kauj ruam txheej txheem.
