Qhov sib txawv tseem ceeb ntawm chlorenchyma thiab aerenchyma yog chlorenchyma yog cov ntaub so ntswg tshwj xeeb parenchyma uas muaj chloroplasts thiab nqa tawm photosynthesis thaum aerenchyma yog cov ntaub so ntswg uas muaj huab cua loj.
Parenchyma cov ntaub so ntswg yog ib qho ntawm peb hom av cov ntaub so ntswg hauv cov nroj tsuag. Parenchyma hlwb yog cov nyob hauv cov hlwb nrog ib tug tseem ceeb nucleus. Lawv muaj cov phab ntsa nyias nyias ua los ntawm cellulose. Tsis tas li ntawd, parenchyma hlwb tsis muaj cov phab ntsa thib ob thiab lignin deposition. Thaum loj hlob, lawv tseem ciaj sia thiab metabolically active. Tsis tas li ntawd, muaj ntau pawg ntawm cov ntaub so ntswg parenchyma. Chlorenchyma thiab aerenchyma yog ob hom ntawm lawv.
Chlorenchyma yog dab tsi?
Chlorenchyma yog ib qho hloov pauv parenchyma cov ntaub so ntswg pom hauv mesophyll cov ntaub so ntswg txheej ntawm nplooj thiab cov xim ntsuab ntawm qee cov nroj tsuag. Cov ntaub so ntswg no muaj ntau chloroplasts, muaj chlorophylls. Yog li, lawv pom muaj xim ntsuab. Txij li thaum lawv muaj chloroplasts, lawv nqa tawm photosynthesis thiab tsim khoom noj rau cov nroj tsuag.
Daim duab 01: Mesophyll Txheej ntawm Nplooj
Ntxiv nrog rau photosynthesis, chlorenchyma cov ntaub so ntswg pab hauv kev khaws cia hauv cov nroj tsuag. Cells ntawm chlorenchyma cov ntaub so ntswg yog isodiametric nyob rau hauv cov duab. Lawv muaj cov phab ntsa nyias nyias thiab tsis ua rau cov thickening theem nrab. Tsis tas li ntawd, lawv muaj qhov chaw nruab nrab ntawm cov hlwb.
Aerenchyma yog dab tsi?
Aerenchyma yog cov ntaub so ntswg uas muaj cov huab cua loj. Piv nrog rau qhov chaw intracellular, cov ntaub so ntswg aerenchyma muaj cov pa loj loj uas tso cai rau lawv txawv ntawm lwm cov ntaub so ntswg. Cov hlwb no muaj nyob rau hauv cov hauv paus hniav thiab stems ntawm wetland nroj tsuag hom. Tsis tas li ntawd, cov ntaub so ntswg aerenchyma muaj ob hom yooj yim: lysigenous aerenchyma thiab schizogenous aerenchyma. Lysigenous aerenchyma loj hlob thaum lub sij hawm cell tuag thaum schizogenous aerenchyma loj hlob thaum lub sij hawm cell sib cais nyob rau hauv wetland nroj tsuag hom.
Daim duab 02: Aerenchyma Tissue
Aerenchyma hlwb yog ib qho tseem ceeb hauv cov qoob loo ciaj sia nyob rau hauv dej-logging tej yam kev mob. Ntxiv mus, cov ntaub so ntswg no muaj txiaj ntsig zoo hauv kev muab cov pa oxygen rau cov cag ntoo.
Dab tsi zoo sib xws ntawm Chlorenchyma thiab Aerenchyma?
- Chlorenchyma thiab aerenchyma yog ob hom parenchyma cov ntaub so ntswg muaj nyob hauv cov nroj tsuag.
- Ob cov ntaub so ntswg tseem ceeb heev rau cov nroj tsuag.
- Ntxiv mus, chloroplasts muaj nyob rau hauv ob daim ntaub so ntswg.
Qhov txawv ntawm Chlorenchyma thiab Aerenchyma yog dab tsi?
Chlorenchyma cov ntaub so ntswg yog hloov pauv cov ntaub so ntswg parenchyma txhawm rau txhawm rau ua kom cov duab ua kom zoo thaum cov ntaub so ntswg aerenchyma yog cov ntaub so ntswg tshwj xeeb uas muaj cov huab cua loj. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm chlorenchyma thiab aerenchyma.
Cov hauv qab no qhia txog qhov sib txawv ntawm chlorenchyma thiab aerenchyma.
Summary – Chlorenchyma vs Aerenchyma
Hauv luv luv, chlorenchyma thiab aerenchyma yog ob hom parenchyma cov ntaub so ntswg uas ua haujlwm tshwj xeeb hauv cov nroj tsuag. Chlorenchyma cov ntaub so ntswg yog cov ntaub so ntswg parenchyma hloov mus ua photosynthesis, thaum cov ntaub so ntswg aerenchyma yog parenchyma cov ntaub so ntswg uas muaj cov huab cua loj. Ntxiv mus, chlorenchyma hlwb muaj ntau nyob rau hauv mesophyll txheej ntawm nplooj thaum aerenchyma hlwb muaj ntau nyob rau hauv cov hauv paus hniav thiab stems ntawm wetland nroj tsuag hom. Yog li, qhov no qhia txog qhov sib txawv ntawm chlorenchyma thiab aerenchyma.
