Qhov sib txawv tseem ceeb ntawm collenchyma thiab chlorenchyma yog tias collenchyma yog ib hom ntawm cov ntaub so ntswg hauv av uas muab kev txhawb zog rau cov nroj tsuag thaum chlorenchyma yog cov ntaub so ntswg hloov pauv uas muaj chloroplasts thiab photosynthetic.
Muaj peb hom ntaub so ntswg hauv av xws li parenchyma, collenchyma, thiab sclerenchyma. Lawv tsis yog dermal lossis vascular. Parenchyma hlwb yog cov nroj tsuag zoo ib yam nrog cov phab ntsa nyias nyias. Lawv tseem ciaj sia txawm tias thaum loj hlob tuaj. Parenchyma hlwb ua raws li cov ntaub so ntswg muab tso rau hauv qhov chaw mos ntawm cov nroj tsuag. Txawm li cas los xij, cov cell collenchyma kuj muaj cov phab ntsa ntawm tes, tab sis lawv muaj cov thickenings theem nrab hauv qee qhov chaw ntawm phab ntsa ntawm tes. Li no, lawv muab kev txhawb nqa txhua yam nrog rau kev txhawb nqa rau cov nroj tsuag. Ntxiv mus, cov hlwb sclerenchyma muaj cov phab ntsa tuab tuab, tab sis cov hlwb no tuag thaum loj hlob. Lawv tsis muaj nucleus thiab cytoplasm nyob rau theem no. Tsis tas li ntawd, lawv yog cov hlwb tseem ceeb uas muab kev txhawb nqa rau cov nroj tsuag. Yog li, chlorenchyma yog ib hom tshwj xeeb ntawm parenchyma cov ntaub so ntswg uas yog photosynthetic.
Collenchyma yog dab tsi?
Collenchyma yog ib qho ntawm peb hom av cov ntaub so ntswg uas muaj nyob hauv cov nroj tsuag. Collenchyma hlwb muaj qhov sib npaug ntawm cov phab ntsa ntawm cov phab ntsa. Lub cell phab ntsa yog tsim los ntawm pectin thiab hemicellulose. Cov hlwb no yog elongated los yog angular nyob rau hauv cov duab nyob rau hauv transverse seem. Cov hlwb no yog cov nyob hauv hlwb txawm tias thaum loj hlob tuaj txawm tias lawv muaj cov phab ntsa ntawm tes. Tsuas muaj qhov chaw me me xwb/tsis muaj qhov chaw nruab nrab ntawm cov hlwb collenchyma.
Daim duab 01: Collenchyma
Feem ntau, cov ntaub so ntswg collenchyma muab kev txhawb zog rau cov nroj tsuag. Epidermal txheej ntawm cov nroj tsuag tsuas yog tsim ntawm collenchymas hlwb. Tsis tas li ntawd, collenchyma hlwb muaj nyob rau hauv nplooj, stems, thiab petioles.
Chlorenchyma yog dab tsi?
Chlorenchyma yog ib qho hloov pauv parenchyma cov ntaub so ntswg tam sim no nyob rau hauv mesophyll cov ntaub so ntswg txheej ntawm nplooj thiab stems ntawm cov nroj tsuag. Cov ntaub so ntswg muaj chloroplasts; Yog li ntawd, nws yog photosynthetic. Nws kuj ua haujlwm cia hauv cov nroj tsuag. Cells ntawm cov ntaub so ntswg chlorenchyma yog isodiametric nyob rau hauv cov duab.
Daim duab 02: Chlorenchyma hauv nplooj nplooj
Cells muaj cov phab ntsa nyias nyias. Lawv tsis dhau cov thickenings theem nrab, tsis zoo li collenchyma hlwb. Tsis tas li ntawd, lawv muaj qhov chaw nruab nrab ntawm cov hlwb, tsis zoo li cov hlwb collenchyma.
Dab tsi yog qhov zoo sib xws ntawm Collenchyma thiab Chlorenchyma?
- Ob leeg collenchyma thiab chlorenchyma hlwb yog cov hlwb nyob.
- Kuj, ob qho tib si yog cov noob qoob loo.
- Tsis tas li ntawd, ob leeg muaj lub nucleus thiab cytoplasm.
- Thiab, lawv yog cov ntaub so ntswg yooj yim.
Qhov txawv ntawm Collenchyma thiab Chlorenchyma yog dab tsi?
Collenchyma cov ntaub so ntswg yog ib hom ntawm cov ntaub so ntswg hauv av uas muaj cov hlwb tsis sib luag thaum chlorenchyma yog cov ntaub so ntswg hloov pauv uas muaj chloroplasts thiab photosynthetic. Yog li, peb tuaj yeem xav txog qhov no yog qhov sib txawv tseem ceeb ntawm collenchyma thiab chlorenchyma. Tsis tas li ntawd, cov ntaub so ntswg collenchyma muab txhua yam thiab kev txhawb nqa rau cov nroj tsuag thaum chlorenchyma cov ntaub so ntswg pab hauv photosynthesis thiab cia. Li no, qhov no yog qhov sib txawv ntawm collenchyma thiab chlorenchyma.
Tsis tas li ntawd, cov cell collenchyma muaj cov phab ntsa tuab tuab tsis sib xws thaum cov phab ntsa ntawm cov chlorenchyma hlwb tsis sib xws. Tsis tas li ntawd, cov ces kaum ntawm collenchyma hlwb raug cuam tshuam thaum qhov kev cuam tshuam no tsis pom hauv chlorenchyma hlwb. Yog li, qhov no yog qhov sib txawv ntawm cov collenchyma thiab chlorenchyma hlwb.
Cov ntawv qhia hauv qab no qhia ntau ntxiv txog qhov sib txawv ntawm collenchyma thiab chlorenchyma.
Summary – Collenchyma vs Chlorenchyma
Nyob rau hauv kev qhia txog qhov sib txawv ntawm collenchyma thiab chlorenchyma, lub collenchyma yog cov ntaub so ntswg hauv av uas muaj cov hlwb tsis sib xws. Hauv qhov sib piv, chlorenchyma yog cov ntaub so ntswg tshwj xeeb parenchyma rau photosynthesis. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm collenchyma thiab chlorenchyma. Tsis tas li ntawd, cov cell collenchyma muab cov khoom siv thiab cov qauv kev txhawb nqa rau cov nroj tsuag thaum chlorenchyma hlwb nqa tawm photosynthesis thiab cia ua haujlwm. Ntxiv mus, collenchyma hlwb yog elongated los yog angular hlwb thaum chlorenchyma hlwb yog isodiametric nyob rau hauv cov duab. Collenchyma hlwb yuav lossis tsis muaj chloroplasts thaum chlorenchyma hlwb muaj ntau dua chloroplasts.
