Kev tsim. Primary plasmodesmata yog tsim thaum cov feem ntawm cov endoplasmic reticulum yog daig thoob plaws hauv nruab nrab lamella li cov phab ntsa cell tshiab yog synthesized ntawm ob tug tshiab faib cog hlwb. Cov no nws thiaj li dhau los ua cytoplasmic kev sib txuas ntawm cov hlwb. … Pits ib txwm ua ke ntawm cov hlwb uas nyob ib sab.
Puas yog plasmodesmata tsim thaum lub sijhawm faib cell?
Primary plasmodesmata yog tsim thaum lub sij hawm faib cell, whereas theem nrab plasmodesmata tsim tag nrho de novo nyob rau hauv cov phab ntsa cell uas twb muaj lawm. … Plasmodesmata tuaj yeem tshwm sim los ntawm cov seem ntawm endoplasmic reticulum sab laug nyob rau hauv lub phragmoplast ntawm ib tug faib cell, thiab cov uas tsim txoj kev no hu ua thawj plasmodesmata.
Plasmodesmata yog dab tsi thiab nws txoj haujlwm?
Plasmodesmata yog cov plasma txoj hauv kev nruab nrab ntawm cov hlwb cog uas yog qhov tseem ceeb tshaj plaws rau thauj, kev sib txuas lus thiab kev taw qhia ntawm cov hlwb. Cov nano-channels no yog lub luag haujlwm rau kev sib koom ua ke ntawm cov hlwb hauv cov ntaub so ntswg thiab rau kev faib tawm ntawm cov nroj tsuag lub cev rau hauv kev ua haujlwm symplast units.
Plasmodesmata pom nyob qhov twg hauv cov nroj tsuag?
Plasmodesmata (Pd) yog co-axial membranous channels uas hla phab ntsa ntawm cov nroj tsuag uas nyob ib sab, txuas cov cytoplasm, plasma membranes thiab endoplasmic reticulum (ER) ntawm cov hlwb thiab tso cai ncaj qha. cytoplasmic cell-to-cell kev sib txuas lus ntawm ob qho tib si me me molecules thiab macromolecules (proteins thiab RNA).
Qhov kev txav yog dab tsikoom nrog hauv plasmodesmata?
Qhov no tau tswj hwm los ntawm cov lus teb rau ntau yam kev loj hlob thiab ib puag ncig cov cim thiab tswj cov passive txav ntawm cov molecules los ntawm plasmodesmata. (C) Cov plasmodesmata tshwj xeeb, hu ua pore plasmodesmata, txuas cov hlwb ua ke (CC) rau cov ntsiab lus sieve (SE) hauv phloem.
