Assimilates suav nrog sucrose, amino acids raug xa mus rau hauv sieve ntsiab lus ntawm nplooj nthuav dav tawm tsam qhov tseem ceeb concentration thiab electrochemical gradients. Cov txheej txheem no yog hu ua phloem thauj khoom. Kev txav los ntawm cov khoom sieve mus rau cov neeg txais lub dab ntxuav tes yog hu ua phloem unloading.

Ib yam li ntawd, dab tsi yog assimilates hauv cov nroj tsuag?

Cuaj hlis 2015) Nyob rau hauv biology, assimilation (kuj bio-assimilation) yog kev sib txuas ntawm ob txheej txheem los muab cov hlwb nrog cov as-ham. Thawj yog cov txheej txheem ntawm kev nqus cov vitamins, minerals, thiab lwm yam tshuaj los ntawm cov zaub mov hauv plab hnyuv.

Qhov thib ob, dab tsi yog thauj los ntawm phloem? Phloem yog cov ntaub so ntswg vascular lub luag hauj lwm rau lub thauj ntawm cov suab thaj los ntawm cov ntaub so ntswg (ex. photosynthetic nplooj hlwb) mus rau cov ntaub so ntswg (ex. non-photosynthetic cag hlwb los yog tsim paj). Lwm cov molecules xws li cov proteins thiab mRNAs kuj yog thauj thoob plaws hauv cov nroj tsuag via phloem.

Ib tug kuj yuav nug, yuav ua li cas assimilates loaded rau hauv phloem?

Assimilates txav mus los ntawm qhov chaw hauv cov xoob cellulose fibers ntawm phab ntsa ntawm tes, hu ua apoplast. Lawv txav mus hauv phloem ntawm diffusion. Active thauj yog siv los tuav ib tug concentration gradient. Hydrogen ions (H +) nquag tso tawm siv ATP.

xylem thiab phloem yog dab tsi?

Xylem thiab phloem . ! Cov xyem thiab cov phloem tsim cov ntaub so ntswg ntawm cov nroj tsuag thiab thauj dej, suab thaj, thiab lwm yam tseem ceeb nyob ib ncig ntawm tsob ntoo. Xylem cov ntaub so ntswg feem ntau yog siv los thauj cov dej los ntawm cov hauv paus hniav mus rau stems thiab nplooj tab sis kuj thauj lwm cov tshuaj yaj.
