Cell kev sib txawv tshwm sim nyob rau thaj tsam ntawm kev loj hlob. Nov yog qhov uas cov hlwb siv tus kheej hais txog dab tsi lawv yuav ua haujlwm nyob rau hauv cov nroj tsuag cov hauv paus hniav. Cov cell dhau los ua parenchyma cells, khaws thiab txav cov as -ham. Los yog, lawv yuav dhau los ua sclerencyma hlwb, uas dhau los ua ib feem ntawm ntawm tes phab ntsa.
Thiaj li, ua li cas hauv thaj tsam ntawm kev loj hlob?
Cov cheeb tsam ntawm elongation yog qhov twg cov cell tsim tshiab tau nce hauv qhov ntev, yog li lengthening hauv paus. Pib ntawm thawj cov hauv paus plaub hau yog qhov cheeb tsam ntawm cell kev loj hlob qhov twg hauv paus hauv paus pib sib txawv ua hom cell tshwj xeeb. Tag nrho peb thaj chaw nyob hauv thawj centimeter lossis li ntawm lub hauv paus ntsis.
Tom qab ntawd, lo lus nug yog, vim li cas cov plaub hau hauv paus tshwm sim hauv thaj tsam ntawm kev loj hlob? Cov cov hauv paus plaub hau yog qhov tsis yooj yim thiab tsuas yog nthuav tawm ntawm cov cell epidermal. Cov thaj tsam ntawm kev loj hlob yog thaj tsam ntawm lub hauv paus qhov twg tag nrho cov hlwb ua haujlwm tau pom. Kev ua haujlwm ntawm hauv paus plaub hau yog kom nce thaj tsam ntawm keeb kwm thiab nqus feem ntau ntawm cov nroj tsuag dej thiab cov as-ham.
Ntxiv mus, thaj tsam ntawm kev sib txawv yog dab tsi?
cheeb tsam ntawm kev sib txawv Thaj chaw hauv cov cag cog uas nyuam qhuav tsim cov cell tsim mus rau ntau hom cell. cheeb tsam ntawm elongation Thaj chaw hauv cov cag cog uas nyuam qhuav tsim cov cell loj tuaj thiab ncua ua ntej kev sib txawv.
Lub hauv paus plaub hau yog dab tsi?
Lub luag haujlwm ntawm cov hauv paus plaub hau yog sau dej thiab cov zaub mov muaj ntxhia uas muaj nyob hauv cov av thiab siv cov tshuaj no los ntawm cov hauv paus hniav mus rau lwm cov nroj tsuag. Raws li cov hauv paus plaub hau plaub hau tsis nqa tawm cov duab hluavtaws lawv tsis muaj chloroplasts.
