Leucoplasts basa. Avilable leucoplasts

Mumwe zviratidzo vamiririri chirimwa umambo huri pamberi mumasero avo anokosha hurongwa - plastids. Vanosanganisira chloroplasts, chromoplasts uye leucoplasts, marongerwo uye mashandiro izvo ichakurukurwa munyaya yedu.

Chii plastids

Organelles anonzi plastids zvirimwa masero, notumwe uye vamwe majemusi. mhuru iyi vakagumisa zvitarisiko kuti vane Semi-zvionera marongerwo. Vanokwanisa interconvert mumwe nomumwe. Somuenzaniso, leucoplasts, marongerwo uye mashandiro iro kuchinja pasi pokudzora zvakananga chezuva vari dzikwanise chloroplasts. Vakawanda vakaona kuti mbatatisi tubers zeleneeyut. Ndiro mugumisiro kunoshamisa yakadaro. Asi kushandisa chigadzirwa yakadai zvokudya hakusi zviripo. Pamwe chete chloroplasts mu tubers zvakachengetwa muchetura - the alkaloid solanine. Kunogona kukonzera chakakomba chikafu chepfu uye kunyanya ngozi vana.

Panguva ichiibvira michero nemiriwo uyewo kunoitika interconversion pamusoro plastids. Chete muchiitiko ichi vari aumba kubva leucoplasts chromoplasts kuziva noruvara siyana dzenyika chirimwa: yero, tsvuku, pink, nezvishava, uye zvichingodaro ..

marudzi plastids

Leucoplasts plastids chromoplasts, chloroplasts zvisingapindirani zvose nemamiriro uye mabasa anoitwa. Asi ivo vose kutamba anokosha uye irreplaceable basa. Kugona kupa ruvara kuti dzakasiyana-siyana chirimwa nokuti kuti chromoplasts ane pigments siyana - colorants.

Corolla inopenya petals zvinomera vakawanda - hwokufananidzira uchapupu kuti. ruvara akadaro seruva munhuhwi chinokwezva nezvipembenene pollination uye muchangosangana izvo kunotangira paumbwe zvibereko.

Green plastids ane ruvara chlorophyll, iyo anosarudza ruvara rwayo. Kuvapo ichi zvinhu (pamwe carbon dioxide, mvura uye chiedza chezuva) ndiye chinodiwa kuti kuerera kubva photosynthesis kwacho. In vadzore zvinomera anoumba makabhohaidhiretsi uye oxygen. Chokutanga ndechokuti kwavari kunobva muviri, kukura. A gasi okisijeni zvose zvipenyu, kubva utachiona vanhu, anoshandiswa kufema.

mamiriro leucoplasts

Leucoplasts vari Hauoneki organelles. Vane idenderedzwa chimiro. Kamudzira wemuTesitamende dzakabudirira asi zvakaneta. Chimiro anogona siyana zvakaipa chete kana ari cytoplasm dzavo kutanga kuumba zvakakwana guru starch mbeu. Leucoplasts plastids zviri stocking kukwira huru chirimwa tishu. Anoumba hwaro okunatsiridza kuti nhungirwa - tubers, Mabumba, rhizomes. leucoplasts nerevane kunorondedzerwa vakadaro zvinoitwa maumbirwo yavo. In organelles izvi mhango anogona kuunganidza zvokudya zvinokosha zvakawanda. Leucoplasts sezvo plastids zvose organelles dvuhmembrannymi. Zvisinei, yomukati goko asingadi kuumba vakasiyana miganhu mukati chivako.

Leucoplasts - masero eukaryotic. Izvi zvinoreva kuti kwavo cytoplasm DNA molecules kuti takura mashoko majini huri wakashongedzwa core.

leucoplasts basa

plastids ava unyanzvi. Zvichienderana mhando, vanokwanisa kuunganidza uye synthesize nekuve Organic zvinhu. Somuenzaniso, carbohydrate starch ane amyloplasts. Izvi zvinhu ndizvo zvinomera zvose, sezvo aumba kubva shuga, yaunganidzwa photosynthesis. Oleoplasty zvibereko uye chitoro mafuta. Liquid mafuta vari rinowanikwawo dzimwe chirimwa masero uye vanonzi nemafuta. Proteinoplast ane mapurotini. Inokonzera basa ndehwevakadai mamiriro leucoplasts. Uyezve mhango waida kuti hunde uye kuchengetera siyana zvinhu zvine makemikari. Izvi zvoutachiona catalysts vanokwanisa mhanyisa dzinongoitika nemakemikari, asi havasi zvigadzirwa zvavo. Nokupesvedzera Somuenzaniso, zviri nyore carbohydrate shuga polysaccharide starch aumbwa. Kana mamiriro ezvinhu simuka izvo vanoshorwa nekuda aibuda photosynthesis, iye zvakare unodokwairira monomers uye kushandiswa pezvakaitwa chirimwa upenyu.

vari leucoplasts Where

Sezvo mukuru basa leucoplasts - ndiko kuunganidza zvinhu, organelles izvi huri thickened uye nenhengo dzine nyama zvinomera. Zvikurukuru akapfuma mbatatisi tubers. mudzidzi mumwe nomumwe anokwanisa kuitisa Qualitative kwomusikirwo starch kuti zviri muna leucoplasts ayo. Kuti aite izvi, unotofanira kupfeka itsva bande ane madonhwe ayodhini mhinduro shoma. Under nawo iyi Hauoneki plastids kuwana munhu mupfumi mushava ruvara. Vanogona kuonekwa pasi maikorosikopu kunyange panguva yakaderera magnification.

Girobhu racho pamusoro chirimwa ndiwo leucoplasts zhinji. Nokuda huru wemvura uye makabhohaidhiretsi midzi zvakadaro vanokwanisa tama pevhu vanoshorwa nguva kwemvura, chando uye nokupisa. Panguva iyoyo akakwidziridza chiduku chikamu chirimwa anofa uye dzakachinjwa kupukunyuka anoramba chine musoro. Somuenzaniso, tulips vari vaviri mavhiki nguva kukura uye ottsvesti. Uye ipapo girobhu racho yavo kuunganidza makabhohaidhiretsi kuumbwa panguva photosynthesis nyoro zvikamu remvura zvinomera.

Havasi Kunze uye rhizomes. Munhu wose anoziva kuti zvakaoma sei kubvisa sora. Havatombonetseki kutya kukuru kwemvura, mashizha uye dzumbunuka pamusoro pasi. The ndechokuti chirimwa pachayo anova pasi pasi ari muchimiro thickened dzakachinjwa kupukunyutsa pamwe elongated internodes. Rine inokosha mari leucoplasts, uye nokudaro nerubatsiro zvinhu.

The endosperm mbeu, fungal spores, OVA dzakakwirira zvinomera kuita mabasa avo akafanirwa pakuvapo plastids mashoko.

Origin leucoplasts

Kuvapo leucoplasts mu embryonic zvinyama zvirimwa zvinenge sabatsira achiri. Ivo akaumba anonzi proplastids. zvivako Ndivo Precursors pamusoro organelles izvi zvose. Pakutanga, vakanga dziri muna meristem - yedzidzo jira miti. Proplastids corpuscles vari nemaziso pakukura kusvika 1 micron. Ndicho yose cheni yacho interconversion izvi organel chirimwa masero inotanga navo.

Saka, mukuru basa iri leucoplasts kwetunhu, kuwanda uye kuchengetera rakasiyana-siyana Organic zvinhu zvakakodzera kuvapo zvipenyu.
