Vacuole - qhov no kab noj hniav uas muaj cov cell kua ntoo

Niaj hnub no peb paub nrog koj, hais tias yog ib tug kab noj hniav uas muaj cov cell kua ntoo. Hais tias yog, peb yuav xav txog lub sij hawm teem ntawm lub cev vacuole. Raws li yog lub npe hu, lub cell - yog qhov yooj yim ntxwv chav tsev ntawm tag nrho cov uas nyob ib ncig peb. Tab sis nws muaj ib tug loj tus naj npawb ntawm organelles. Ib tug ntawm lawv zoo li ib tug kab noj hniav uas muaj cov cell kua ntoo, thiab nws muaj lub npe ntawm tus vacuole.

Lub zog ntawm cov organelles yog heev ntau haiv neeg, peb yuav nco ntsoov them sai sai no lub npe. Tam sim no koj yuav tsum to taub hais tias cell vim nws organelles, nws muaj peev xwm sawv ntawm ywj siab hav zoov. Cov me me hais tsis tas ua ke nyob rau hauv tej complexly qauv. Nws muaj ib tug xov tooj ntawm thaj chaw uas tso cai rau nws nyob ua ib ke ntawm nws tus kheej. Tam sim no cia peb kawm txog ib ntawm lub qhov chaw, ua ib qho tseem ceeb luag hauj lwm nyob rau hauv tus txheej txheem ntawm cell kev ua si.

vacuole

Yog li ntawd peb tau hais tias cov kab noj hniav uas muaj cov cell kua ntoo, yog hu ua cov vacuole. Qhov no organelle yog lawm ua tus sau nrog ib tug aqueous tov ntawm ntau yam tshuaj, cov uas peb yuav nrhiav tau ob qho tib si organic thiab inorganic. koj yuav tsum tau los tsim vacuoles:

• EPS.
• Golgi apparatus.

Peb pib nrog lub fact tias tag nrho cov cog hlwb muaj organelles cov ntaub ntawv, tsuas yog nyob rau hauv lub tub ntxhais hluas yog ntau npaum li cas. Yog vim li cas yog no mas? Raws li ib tug tshwm sim ntawm lawv fusion txoj kev loj hlob tshwm sim, uas ua nyob rau hauv lub tsim ntawm lub hauv paus vacuole. Nws yog ib qho tseem ceeb yuav tau nco ntsoov hais tias tus paub tab cog ntawm tes yog yuav luag tag lawm ua tus sau nrog rau qhov no vacuole (tshaj 90 feem pua). Nyob rau tib lub sij hawm tag nrho cov lwm yam organelles thiab lub nucleus ntawm lub cell txav mus rau lub plhaub.

Vacuole limited tonoplast thiaj hu ua daim nyias nyias ntawm cov nroj tsuag cell organelle. Uas kua uas yog nyob rau hauv lub vacuole - qhov no cell kua ntoo.

Yog li, cov kab noj hniav uas muaj cov cell kua ntoo thiab muaj qhov ntev ntau dua 90 feem pua ntawm tag nrho cell kab noj hniav, - ib tug central vacuole. Muaj pes tsawg leeg ntawm no kua txiv xws li ib tug heev loj tus naj npawb ntawm tshuaj, xws li:

• ntsev;
• monosaccharides;
• disaccharides;
• amino acids;
• glycosides;
• alkaloids;
• anthocyanins, thiab hais txog.

zog

Kab noj hniav hlwb lawm ua tus sau nrog cell kua ntoo, muaj ib lub npe - tus vacuole. Nws ua ntau txawv zog. peb qhia rau xav txog lawv tam sim no. Yuav pib, koj muab lawv nyob rau hauv ib daim ntawv teev:

• dej haum. Dej yog qhov tseem ceeb rau tus txij nkawm ntawm cov nroj tsuag thiab cog lub neej. Tsis tas li ntawd H2O molecules yuav tsum tau kev cog photosynthesis.
• Coloring nroj tsuag. Qhov no yuav tau vim lub xub ntiag ntawm anthocyanins tshuaj. Lawv muaj peev xwm mus rau xim lub cev ntawm cov nroj tsuag (txiv hmab txiv ntoo, paj, nplooj).
• Xaus ntawm tej yam tshuaj lom. Nyob rau hauv lub vacuoles tshwm sim shelving oxalate muaju. Ib txhia theem nrab metabolites muaj zoo (pab) zog, piv txwv li, muab cov nroj tsuag ib tug iab saj, thiab txuag lawv los ntawm kev noj mov.
• Mov cov as-ham. Lub cell yuav optionally coj kom zoo dua ntawm stocks vacuoles, raws li nws stores ib tug xov tooj uas pab tau tshuaj rau lub hlwb.
• Splitting lub qub qhov chaw ntawm lub cell los ntawm kev ua cov yas latex.

Vacuoles nyob rau hauv cov tsiaj hlwb

Peb twb hais tias cov kab noj hniav nyob rau hauv lub cytoplasm, uas muaj cov cell kua ntoo - yog lub vacuole. Tab sis ua ntej uas seem twb hais tsuas hais txog cov nroj tsuag hlwb. Tam sim no peb mam li saib cov zog ntawm qhov no organelle nyob rau hauv cov tsiaj.

Vacuoles yog tam sim no nyob rau hauv feem ntau ntawm cov nyuaj kab mob. Yog li ntawd, piv txwv li, yog pulsating nyob rau hauv dej tsis qab ntsev thiab yog siv rau cov osmotic kev cai. Ib txhia unicellular multicellular vertebrate thiab muaj digestive vacuoles, uas muaj loj nyiaj ntawm cov sib txawv enzymes. Nws yog ib qho tseem ceeb kom paub tias kuj hais tias tus siab tsiaj ntaub ntawv organelles tsim nyob rau hauv phagocytes.

Qhov txawv ntawm nroj tsuag thiab tsiaj hlwb

Peb twb hais tias cov organelles, uas yog muaj kab noj hniav uas muaj cov cell kua ntoo, pom ob leeg nyob rau nroj tsuag thiab nyob rau hauv cov tsiaj hlwb. Yuav ua li cas yog qhov txawv ntawm lawv? Nws yog ib qho tseem ceeb kom to taub tias nyob rau hauv lub cell lawv tsis nyob rau hauv ib kom muaj nuj nqis. Cov nroj tsuag lawv tuav 95 ib xees, thiab nyob rau hauv tus tsiaj - tsuas yog 5 feem pua.
