Yintoni ukubaleka? isakhiwo ukubaleka

inxalenye kwakufa kwisityalo ekuthiwa elithi "ukubaleka". Ubume kungenxa imisebenzi eyenziwa. Kakade ke, onke amalungu buyafuneka kwaye imisela ithuba ubukho lweentlobo. Imisebenzi ye isondlo, iinkqubo ukukhula, ukuze zikwazi ukumelana - ezi nje ezinye weyona misebenzi ibaluleke inxalenye ebonakalayo eziphilayo zezityalo.

Biology: Ulwakhiwo ukubaleka

Le morphology ukwahlula iinxalenye yezihlunu kwaye zisecaleni umzimba: isiqu namagqabi. Indlela esakhiwe ngayo esi sityalo emahlamvini awo aphezulu eyenza nezinto: ukusuka duckweed obungabonakaliyo machibi ukuba kwihlathi umsequoia. Kungenxa isakhiwo eyahlukileyo amacandelo inxalenye zasemoyeni, enxulumene iimpawu kokusingqongileyo kunye neemeko zemozulu. Kukho kwakhona asisifutshane amahlumelo osandul - nezintso.

Kuqhotyoshelwe iphepha ukubeka isahlulo shaft kuthiwa udumbo, kwaye angle oluthi luqokelelane phakathi kwabo, - esifubeni. Kukho kuye ezizodwa kidney, akha amagqabi okanye iintyatyambo. Umgama phakathi kweendawo ezimbini igqabi attachment ekuthiwa Embi.

stem

Ulwakhiwo ukubaleka kuqala kuxhomekeka kwicala lokukhula kunye nendawo esithubeni isiqu. Kuxhomekeka ezi mpawu Ukwahlula nkqo, kuse ezinambuzaneni, ukukhasa, ukucaca sibambelele iintlobo. Iziqu kunye nohlobo olwahlukeneyo kumphezulu. Kunokuba ze okanye iinkqubo, kakuhle okanye rough. Ukuba uthe wagawulwa likhaba crosswise, kunokwenzeka ukuba ukujonga imilo: ngeenxa zonke, exabe, kunye nenani ubuso okanye atshabalalisa.

Ukuba intshebe amaqunube nawo ubalekayo, ukuba internodes iyanqanyulwa.

Kuxhomekeka kuhlobo lobomi ukwahlula herbaceous kunye enemithi iziqu. Eyokuqala ayinayo cambium - icala yemeko lemfundo. Kwiminyaka yokuqala yobomi ayafana ukubonakala amahlumelo amatsha kwemithi namatyholo. Bona eluhlaza ngebala kwaye ezinako photosynthesis. Ekubeni kokuba lignified ngokuhamba kwexesha, ngokuya ixesha elide ngakumbi. Bona bayakwazi babambelele iziqhamo ezinkulu ukumelana zemimoya olomeleleyo umoya.

types of olubangelwa

Kuxhomekeka iimpawu zomjikelo uphuhliso kwisityalo ibe ngabo-, iimo, kwaye ixesha elide. Umzekelo, Aster kubunela ekwindla, emva koko afe ngokupheleleyo. Ngamanye asakhasayo iminqathe kunye beetroot. Kunyaka wabo wokuqala bezelwe, bakha iingcambu, leyo imizimba igcinwe izondlo. Xa ekwindla le iyafa esiqwini. Kodwa ke isityalo iluhlobo lwe isiqu iguqulwe kancinane. Xa kuqala iimeko ezithandwa ukubaleka ukhula umva. Kulo mzekelo, ngomnyaka wesibini kobomi kwakheka ngenxa imbewu eneentyatyambo, leyo ekhuthazwa izityalo.

Umjikelo wobomi izityalo ingaphelelwayo, cinga ukuhlolisisa iimpawu noshowo Conifers emthini. Le ityholwana okanye umthi kunye stem ngamandla single - buti. uphuhliso yawo luqala nokuntshula kwembewu. kwakhiwa isithombo, yaye, emva kokuba ngenxa yayo lokukhula - izityalo abadala. Igcina umjikelo wobomi ingaphelelwayo izityalo yokufa. Conifers zithathwa ukuba babe ngabantu bokwenene. Umzekelo, nompleyini ubomi iminyaka malunga 400, nespruce - phezulu ukuya 500, yaye konwele - njengoko 1000!

sheet

Inxalenye zisecaleni ihlumelo ubuncinane obusebenzayo nezahlukeneyo. Inika umoya enikwe, transpiration - komphunga amanzi avela kumphezulu andise kwezityalo. Balekela, ogama Isakhiwo obuslovlovleno imisebenzi eyenziwa, esibonakala ezahlukeneyo amagqabi.

Cactus iinaliti kufuneka ukunciphisa isixa ukufuma ngumphunga. A palmate zivuleke nezompleyini ihashe, phezu koko, ukunyusa umthamo wayo.

Ihamba nge plate mnye kuthiwa elula, kodwa ambalwa ibekwe kwi petiole enye - ezintsonkothileyo. Xa ucinga, kusenokwenzeka ukuba nawe ubona indlela ethile. Idala yegazi. Oku iinyanda fibrovascular of ilaphu conductive. Bubunjani venation umahluko amagqabi kunye enemingxuma (maple, apile), enxuseneyo (ingqolowa, irye) kunye arc (ngeplantain lily) mibala.

Phyllotaxy

Balekela, isakhiwo apho ixhomekeke kwinani amandla elanga ezifunyenweyo, ebonakala ngu ilungiselelo ezahlukahlukeneyo amagqabi esiqwini. Kwimeko ilungiselelo ezijikeleze ibunjiwe elandelayo, kwaye ukuba isangqa - esahlukileyo, okanye verticillate.

Endalweni akukho kwizityalo ukubuyekeza njengamagqabi. It licwangcisa kunye nompleyini zemisipres. Ukususela kokuwa, hayi onke amagqabi kwangoko, akukho mntu izaziso.

kokulungiswa ukubaleka

Xa ufuna ukwenza imisebenzi eyongezelelweyo luphinde ludubuleke kunye namacandelo zabo ilungiswe. Amagqabi zitshintshwe zibe ameva okanye isikali. I ezizingelayo zezityalo, bayakwazi ukubamba ukwetyisa izinambuzane ezincinane.

Iimpawu lwesakhiwo ukubaleka ngazo mzekelo kwezibane. stem yakhe caba kancincane ngokuba "ipleyiti Uhlobo Lokuqala". It has eziliqela iindidi amagqabi: zimnandi - okugcina amanzi kunye nezondlo, owomileyo - ukuze sikhuseleke. Ngaphezu koko, izintso phambi amanzi awaneleyo ukukhula amagqabi abaselula eluhlaza. Ukususela stem kwakhona ikhula iingcambu ezinezikhondo.

Le amatswele of artichoke iYerusalem, ekwabizwa ngokuba artichoke lwakha ukuguqulwa ukubaleka - le tuber. On anquma ehlangeni nenyama zizinto amathupha rubtsevidnye, ukusuka apho kukhula emthini.

Zaphantsi komhlaba iziqu kunye internodes obude rhizomes. Bafana isabhokhwe, ziye ephuhliswe kakuhle ilaphu ngoomatshini kunye conductive. Kidney ekwikhompyutha enabayo kwasekwa amagqabi. Abo ezintsha iimpawu noshowo le rhizomes, kholwani ukuba balahle amagqabi, yonke isityalo uyafa. Kodwa lo mbono nto eziphosakeleyo, kuba kwindawo engundoqo ye kwisityalo lukhuselwe kwaye phantsi komhlaba.

Ukuzalana isakhiwo kunye nemisebenzi

Ulwakhiwo ukubaleka kuxhomekeke imisebenzi eyenziwa. Oku icikidwa ngokuqwalasela iziqalelo ubume iinxalenye zayo. Eli phepha isale izihlunu abahlala ngaphandle yesikhumba esikhoyo kuyo kukho imingxunyana - yokondliwa. Kuba iyimfuneko ukhuselo nokutshintshiselana sukube. Le internals wetshati amelwe lelonani kunye yiklorofili inyama leyo ajongene nokondliwa autotrophic yonke isityalo. Elements of conductive kunye zomzimba mechanical, imithambo ukwakha, zezona isiseko ukuthutha yonke uluhlu izondlo eziyimfuneko.

amalungu zezityalo kwezityalo uyingcambu (inxalenye komhlaba kuyo) kunye ubaleka. Ubume bale amalungu okuzala akavumi ukuba enze imisebenzi enjalo. Abawenza inkqubo ukuzala izityalo andise. Kodwa imbali ukuqulunqa esiqwini, nangenxa nophuhliso kwakhe izinto eziyimfuneko zemvelo kwasekwa emagqabini.

Oku kunokwenziwa isigqibo sokuba isityalo luyinto eyodwa, iindawo asebenza kuzo ezihambelanayo.
