Chromoplasts muaj nyob rau hauv txiv hmab txiv ntoo, paj, cov hauv paus hniav, thiab kev ntxhov siab thiab laus nplooj, thiab muaj lub luag haujlwm rau lawv cov xim txawv. Qhov no yeej ib txwm cuam tshuam nrog kev nce loj hauv kev sib sau ntawm carotenoid pigments. Kev hloov pauv ntawm chloroplasts rau chromoplasts hauv ripening yog ib qho piv txwv classic.
Chromoplasts pom nyob rau hauv ib tsob nroj nyob qhov twg?
Chromoplasts yog plastids uas muaj xim vim yog cov xim uas tsim thiab khaws cia rau hauv lawv. Lawv muaj nyob rau hauv txiv hmab txiv ntoo, paj, hauv paus, thiab nplooj senescent. Cov xim ntawm cov nroj tsuag no cuam tshuam nrog cov pigments, sib nrug ntawm chlorophyll.
Chromoplast Class 9 yog dab tsi?
Chromoplasts yog plastids thiab muaj carotenoids. Lawv tsis muaj chlorophyll. Carotenoid pigments yog lub luag hauj lwm rau cov xim sib txawv xws li daj, txiv kab ntxwv thiab xim liab imparted rau txiv hmab txiv ntoo, paj, nplooj qub, cov hauv paus hniav, thiab lwm yam. Chromoplasts yuav tsim los ntawm ntsuab chloroplasts.
Chromoplast nyob qhov twg hauv nplooj?
Hint: Cov hlwb cog muaj chloroplasts, chromoplasts, leucoplasts thiab plastids. chromoplast yog liab thiab daj los yog xim. Lawv pom hauv paj paj thiab txiv hmab txiv ntoo.
Qhov twg ntawm cov nroj tsuag muaj ntau cov chromoplasts?
puv puv pericarp hlwb muaj ntau tus chromoplasts, tshwm li ntsuab vim yogtshwj xeeb fluorescence ntawm GFP thaum tsis muaj chlorophyll (Forth thiab Pyke 2006). Qhov loj ntawm plastid txawv ntawm qhov loj hlob ntsuab mus rau theem puv puv, chromoplasts yog me dua chloroplasts.

Qhov twg hauv qab no yog piv txwv ntawm geotropism hauv cov nroj tsuag?
Lub ntsiab lus ntawm geotropism yog kev loj hlob ntawm cov nroj tsuag lossis tsiaj tsis tuaj yeem teb rau lub zog ntawm lub ntiajteb txawj nqus. Ib qho piv txwv ntawm geotropism yog cov hauv paus hniav ntawm cov nroj tsuag loj hlob mus rau hauv av.
Cov fibers thiab sclereids nyob qhov twg hauv cov nroj tsuag?
Cov fibers no muaj nyob hauv lub cortex, thiab xylem thiab phloem ntawm cov nroj tsuag. Fibers muab cov neeg kho tshuab kev txhawb nqa. Hom sclereids yog Macro, osteo, Astro, Brachy sclereids. fiber ntau pom nyob rau hauv ib tsob nroj nyob qhov twg?
Qhov twg yog qhov tshwm sim tom qab fertilization hauv cov nroj tsuag?
Vim li no cov lus teb yog kev xaiv B, Embryo kev loj hlob . Hauv qab no yog daim duab ntawm embryo tsim embryo tsim Hauv kev loj hlob biology, embryonic kev loj hlob, tseem hu ua embryogenesis, yog kev loj hlob ntawm tus tsiaj lossis cog embryo.
Ntawm twg ntawm cov nroj tsuag muab elaioplast pom?
Lub luag haujlwm tseem ceeb ntawm elaioplasts yog synthesis thiab khaws cia ntawm fatty acids, terpenes, thiab lwm yam lipids, thiab lawv tuaj yeem pom hauv embryonic nplooj ntawm oilseeds, citrus txiv hmab txiv ntoo, raws li zoo li cov anthers ntawm ntau flowering nroj tsuag.
Cov nroj tsuag sab hauv tsev hauv cov nroj tsuag?
Cov nroj tsuag zoo tshaj plaws hauv tsev muaj xws li hauv qab no: Aglaonema - Nws yog qhov txaus nyiam, zam lub teeb qis, thiab tsis loj hlob sai. Aspidistra - Koj yuav tsum tsis txhob muab dej ntau thiab nws yuav ua rau lub teeb qis. … Succulent - Nco ntsoov tias koj muab lub teeb ci rau lawv.
