Avilable columnar ntaub so ntswg: kev sib raug zoo ntawm cov qauv thiab muaj nuj nqi

Avilable columnar nplooj cov ntaub so ntswg yog lub luag hauj lwm rau qhov kev siv ntawm nws ib qho tseem ceeb functions. Nrog rau qhov no ua txhua yam tseem ceeb heev functions ntawm cov nroj tsuag kab mob. Nyob rau hauv no tsab xov xwm peb yuav saib yus nta ntawm lub cev thiab tej hlab ntshav ntawm cov ntaub so ntswg columnar.

Nta ntawm lub internal qauv ntawm nplooj

Cov nroj tsuag yog nyob rau hauv ib lub bar ntaub ntawv. Yuav ua li cas yog lub cev? Los ntawm cov sab nraum nws yog them nrog daim tawv nqaij. Qhov no zoo ntawm cover ntaub muaj nruj nreem packed nyob hlwb, cov uas lub stomata muaj nyob rau. Vim cov ntaub ntawv lug muab lub allergic ntawm gaseous molecules: pa - mus rau hauv ib tsob nroj, thiab cov pa roj carbon dioxide thiab dej vapor - nyob rau hauv kev coj rov qab.

Nyob rau hauv daim tawv nqaij nyob ntsiab photosynthetic cov ntaub so ntswg hlwb. Lawv yog cov loj, dim de txheej txheem, yog li ntawd lub hauv paus ntawm daim ntawv. Thiab ib tug conductive kev pab txhawb nqa kev ua yog ua hlab ntsha - ib tug txheej ntawm conductive ntsiab thiab cov neeg kho tshuab cov ntaub so ntswg. Ua ke lawv tsim fibrovascular bundles.

Lub hom nplooj cov ntaub so ntswg

Lub ntsiab ntaub muaj ob cell hom: columnar thiab li ntaub nqus dej. Cov yav tas muaj ib lub voj qe, thiab nyob rau hauv lub Team sib nruab nrab ntawm lawv yog cov intercellular qhov chaw. Cov lug coj tau ib tug peb lub hlis twg ntawm daim ntawv. Hais ntawm lub hauv paus ntaub nrog intercellular qhov chaw ua lub hauv paus ntawm daim ntawv lub khw li ntau yam tshuaj muab kev koom tes nyob rau hauv roj pauv. Nta ntawm cov qauv ntawm cov columnar cov ntaub so ntswg ua rau nws lub ntsiab qauv ntawm cov photosynthetic nplooj.

Xam columnar hlwb ntawm nplooj nqaij thiab tshwj xeeb qhia txog nws qhov chaw nyob. Nws yog nyob ncaj qha nyob rau hauv daim tawv nqaij nyob rau hauv sab saum ntawm cov nplooj. Lub hlwb ntawm cov ntaub so ntswg, yeej reminiscent ntawm cov tuav, yuav tsum muab tso rau hauv ib los yog ntau tshaj kab. Qhov no arrangement yog vim nws yooj yim zog - photosynthesis. Nws yog qhov zoo rau qhov haum ntawm cov pa thiab tshav ntuj.

Lub Khoos Loos Tsev nta ntawm cov ntaub so ntswg columnar

Lub bar yog ib hom ntawm cov ntsiab ntaub so ntswg ntawm cov nroj tsuag. Nws hlwb yog cylindrical rau hauv cov duab, positioned mas thiab zoo nyob ib sab mus rau txhua lwm yam. Cov nab npawb ntawm cov khaubncaws sab nraud povtseg ntawm columnar cov ntaub so ntswg nyob rau hauv lub khov ntawm cov hnub ci tawg. Piv txwv li, nyob rau hauv lub nplooj ntawm cov nroj tsuag uas loj hlob nyob rau hauv lub teeb, tej zaum yuav muaj ob peb. Ib tug ntxoov ntxoo-thaiv tsiaj nyob rau hauv no cov ntaub so ntswg yog tsis zoo tsim.

Xam columnar hlwb ntawm nplooj ntawv so ntswg qhia tau hais tias nws yooj yim qauv. Qhov no nyias plhaub, lub nucleus, mitochondria, Golgi complex, EPS. Lub hauv paus txoj hauj lwm thiab lub ib thooj ntawm cov cell vacuole occupies. Qhov no kab noj hniav yog sau nrog tus cell kua txiv, nws yog ib yam ntawm cov reservoir rau cov dej thiab tshuaj yaj nyob rau hauv nws. Vim muaj cov chloroplasts, lub columnar hlwb cov ntaub so ntswg yog ntsuab, muab rau nws thiab rau tag nrho cov daim ntawv.

Photosynthetic tej zaum yuav txawv qhov chaw ntawm cov nroj tsuag. Piv txwv li, lub cactus, cov nplooj uas yog txo nyob rau hauv cov pos, qhov no feature muab ib tug fleshy soj caum. Peev xwm ntawm photosynthesis, thiab ntau tus hluas-celled kab mob: chlamydomonas, euglena ntsuab, cyanobacteria.

Columnar hlwb muaj coob coob ntawm chloroplasts nyob rau hauv kev sib piv nrog rau lwm cov ntsiab ntawm lub hauv paus ntaub. Yog li ntawd, lawv lub ntsiab muaj nuj nqi - photosynthesis. Nws tseem ceeb yuav tsis yog yuav overestimated, ces nws tau txais yog feem ntau hu ua planetary.

Qhov no photochemical txheej txheem tshwm sim nyob rau hauv lub puab chloroplast membrane kawm rau cov nyob rau ntawm tshav ntuj, carbon dioxide thiab dej. Cov khoom ntawm tshuaj tiv thaiv no, qabzib yog ib tug monosaccharide. Nws cog yog siv raws li ib tug lub zog qhov chaw uas yuav tsum tau rau nws txoj kev loj hlob thiab kev loj hlob. Chained, qabzib ntaub ntawv ib tug complex carbohydrate cov hmoov txhuv nplej. Nws granules yog tso rau hauv cia nyob rau hauv lub cytoplasm nyob rau hauv daim ntawv ntawm cov inclusions.

Qhov thib ob cov tshuaj tiv thaiv cov khoom ntawm photosynthesis yog oxygen. Qhov no roj - ib tug prerequisite aerobic ua pa, uas yog lub ntsiab feature ntawm tag nrho lub neej nyob rau hauv lub ntiaj teb. Lub essence ntawm no yog cov oxidation uas muaj organic tshuaj nrog ib tug tso tawm ntawm lub zog ntawm tshuaj bonds. Lub Khoos Loos Tsev nta ntawm cov ntaub so ntswg thiab muab ib tug columnar orientation ntawm lub chloroplasts, uas tso cai rau lawv mus tshav ntuj yuav tau yuav nraaj.

Yog li ntawd columnar cov ntaub so ntswg yog ib yam ntawm cov yooj yim. Nws hlwb elongated cylindrical zoo thiab pov tseg mas hauv qab no lub sab saum toj daim tawv nqaij daim ntawv. Tso cai columnar cov ntaub so ntswg vim yam ntxwv nta: nws hlwb muaj chloroplasts plastids ntawm ntsuab thiab muab txaus photosynthesis. Tus txheej txheem ntawm planetary qhov tseem ceeb qhia txog lub ntsiab tej yam kev mob ntawm lub neej. Raws li ib tug tshwm sim ntawm nws cov nroj tsuag muab organic teeb meem, vim uas yog tej yam ua kua, thiab tag nrho lwm cov kab mob - oxygen uas yuav tsum tau rau respiration.
