Tus qauv ntawm cov nroj tsuag cell

Tus qauv ntawm cov nroj tsuag cell yog ib tug me ntsis txawv los ntawm lub cellular lug ntawm cov tsiaj. Qhov no yog feem ntau vim rau txoj kev uas lub neej nyob rau hauv ib tug tshwj xeeb txoj kev nroj tsuag thiab lub hwj chim - nrog ib tug ob peb yam xwb tag nrho cov zaub cov kab mob no yog autotrophs, thiab muaj peev xwm ntawm txoj kev lawv tus kheej organic teeb meem los ntawm inorganic. Nyob rau hauv feem ntau qhov organic ntsiab yog tsim los ntawm photosynthesis. Interestingly, lub secreted xwb oxygen yog ib tug byproduct ntawm photosynthetic tshua.

Cov nroj tsuag cell: cov qauv ntawm cov plhaub

Muaj ib cov khoom cell phab ntsa - qhov no yog ib tug ntawm cov yam ntxwv ntawm cog hlwb. Yog li ntawd xav txog cov qauv ntawm cov nroj hlwb yog tsim nyog nrog rau qhov no kev tivthaiv. Qhov no qauv tsim ib cov neeg kho tshuab kev tiv thaiv ib ncig ntawm lub protoplast. Tsis tas li ntawd, cov phab ntsa yog ib hom ntawm ion qhov twg los, thiab ib tug tua teeb meem. Peb tsuas thawj plhaub tsim tau cai cov tub ntxhais hlwb. Lub ntsiab Cheebtsam ntawm cov qauv yog cellulose fibers, hemicellulose thiab pectin. Raws li rau lub thickness, nyob rau hauv hom sib txawv, qhov no daim duab yuav sib txawv.

Nyob rau hauv tus txheej txheem ntawm tseem ceeb heev cell phab ntsa yuav nkoog. theem nrab thiab tertiary phab ntsa tsim tshwm sim los ntawm kev thov successive khaubncaws sab nraud povtseg mus rau lub thawj plhaub. Heev feem ntau, muaj yog deposition ntawm lignin los yog suberin nyob rau hauv kab noj hniav ntawm cellulose fibers - yog li lub cell yuav tsis loj hlob los yog nthuav.

Tus qauv ntawm cov nroj tsuag cell: lub yooj yim hais txog qhov protoplast

Protoplast cell muaj ib tug nucleus, lub cytoplasm, thiab lwm yam organelles. Nws yuav tsum tau muab sau tseg tias cell organelles yuav tau muab faib mus rau hauv daim nyias nyias thiab uas tsis yog-daim nyias nyias.

Lub cytoplasm yog ib tug multicomponent system nyob rau hauv uas muaj cov yooj yim cov kauj ruam metabolism thiab thauj. Lub cytoplasm muaj ib yam khoom uas microfilament network - nyias fibrous cov nqaijrog, uas ua rau lub zog ntawm lug. Ntawm no muaj microtubules thiab centrioles, uas yog muab kev koom tes nyob rau hauv mitotic cell division.

Lwm pab pawg neeg ntawm ib qho tseem ceeb organelles - ib tug ribosome, uas yog ib tug uas tsis yog-daim nyias nyias qauv. Txhua ribosome muaj me me thiab cov loj loj subunits. By thiab loj, cov organelles yog tsis muaj dab tsi lwm tus tshaj ib tug complex protein cov ntsiab thiab tej ribosomal RNA. Tej lug yog muab kev koom tes nyob rau hauv protein synthesis.

Tus qauv ntawm cog hlwb: characterization ntawm daim nyias nyias organelles

Feem ntau ntawm cov Cheebtsam ntawm cov nroj tsuag cell muaj ib tug membrane.

Core - me me kheej kheej los yog elongated chaw uas muaj xws li cov nucleolus, nucleoplasm, chromatin thiab lub nuclear lub hnab ntawv. Lub ntsiab muaj nuj nqi ntawm lub nucleus - cov kev hloov ntawm caj ces, thiab RNA synthesis.

Endoplasmic reticulum yog ib tug system ntawm canals thiab tso tsheb hlau luam. Muaj granular EPS (nws saum npoo yog them nrog ribosomes) thiab tus EPS. Cov kev ua ntawm no organelle yog heev ntau haiv neeg. Yog tsim rau ribosomes protein Cheebtsam uas tau ces kuaj nyob rau hauv ib tug kev hloov kho ntawm twb Eps tso tsheb hlau luam. Tsis tas li ntawd, tus qauv luag hauj lwm rau cov thauj ntawm tshuaj.

Vacuole - daim nyias nyias qauv uas muaj cell kua ntoo. Qhov no organelle koom tes rau osmotic tshuav nyiaj li cas thiab muab cov cell turgor. Ntxiv mus, nyob rau hauv lub vacuole sau ruaj tshuaj uas ces ntawm lub tsim ntawm bubbles yog ntiab tawm rau sab nraum. Tej zaum nyob rau hauv lub cell kua ntoo yaj tshuaj pab tau hloov.

Plastids - ib feem ntawm cov nroj tsuag ntawm tes. Nyob rau hauv feem ntau tus neeg mob, lawv uas hais chloroplasts. Plastids muaj ob tus neeg zoo li, lub puab protrusion txoj kev - thylakoids. Nws muaj lub teeb-sensitive pigments. Nws yog nyob rau hauv lub chloroplasts ua li ib qho tseem ceeb dab ntawm photosynthesis.

Cov nroj tsuag cell organelles muaj lwm yam - yog mitochondria (lub luag hauj lwm rau cellular ua pa), Golgi apparatus (muab redistribution thiab thauj tej nyob rau hauv lub hlwb).

Txawm li cas los, lub ntsiab nta ntawm cov nroj tsuag cell qauv pom - nws muaj ib tug muaj zog cell phab ntsa, vacuole thiab plastids system.
