Ukuguqulwa amahlamvu isitshalo

Njalo ingxenye isitshalo ukugcwalisa imisebenzi yayo eziyisisekelo esekelwe izici oyiyo. Kodwa ukuguqulwa amaqabunga, kanye neminye imigwamanda efanele, siyivumele ukuba ukuthenga more and more. Ngokuvamile bathembele isimo sezulu kanye nemibandela ezikhulayo.

Ukuguqulwa amahlamvu tropical

Izitshalo ezinomswakama amahlathi enkabazwe ufunde silula - kusukela ukuma alandisa Usayizi izindwani leaf. Esikhathini tropical sezulu zone amafomu ukhuni anesikhundla evelele, okwenza ukuthi kungenzeka ukuba uphile nezihlahla kuphela umthunzi-ukubekezela utshani. Iqabunga ngemicu izitshalo ezinkulu futhi ububanzi ngokungavamile. Indlela ukuchaza isakhiwo esinjalo? Into wukuthi omunye imisebenzi le ngxenye, kungaba ukuqala transpiration. Le nqubo yamanzi ukuhwamuka ebusweni ishidi. I emikhulu blade endaweni, bazolokhu exchange gaseous nge imvelo. Ezimweni ezimanzi kumane nje ezidingekile ukuze uvimbele inqubo ukuwohloka.

ameva

Namakhakhasi - liphinde ukuguqulwa amaqabunga simila. Ziyakwazi salabo ezimila Isomiso nethafa. Wonke umuntu wabona ameva a cactus. Lena amaqabunga awo. Ukuswelakala kokusebenza ngokuhlanganyela izimo umswakama lapho inqubo transpiration kumele zincishiswe, kuba kudivayisi ekahle. Njengoba indawo lamina amancane amanzi iyasha kancane kakhulu.

Nokho, ameva a cactus lomtholo - ukushintshashintsha ezahlukene amaqabunga. Uyini umehluko? Thina ngomuthi, hawthorn, blackthorn, Barberry, nezinye izitshalo ezifanayo ameva kuthiwa Ushintshe stipules, hhayi amarekhodi. Umsebenzi wawo oyinhloko ukuvikela izimbali elimnandi kanye izithelo amnandi ukudla ezihlukahlukene izilwane.

izinaliti

Ukuguqulwa amaqabunga izinaliti yikho konke abamele uMnyango gymnosperms. Wonke umuntu uyakhumbula imfumbe yezingane mayelana noboya-isihlahla - ". Ebusika kanye nasehlobo elilodwa umbala" Futhi zonke siluhlaza AmaConifers abangazazi sibonga nokulungiswa nobuntu amahlamvu. Ingxenye evundlile banalo round noma ukuma ribbed. amashidi ezinjalo endaweni encane, njenge cactus ameva. stomata yabo, lapho negesi lokushintshisana senzeka, afakwa enamathela futhi ingxenye enkulu yomsebenzi ishidi. Lokhu kunciphisa izinga lamanzi ukuhwamuka. Ebusika, lezi zokwakheka ngokuphelele uphawu ngemakhilayoni, okuyinto kunciphisa transpiration cishe zero. Ngakho-ke, ngesikhathi lapho zonke angiosperms bechitha amaqabunga awo ebusika, zezihlahla nezihlahla kungaba ozibongayo aluhlaza umhlobiso oluhlaza.

Ihamba izimila zasogwadule

Survive e Isomiso izitshalo nzima. Nokulungiswa kubangelwa amaqabunga lezi zitshalo? Badinga ukuba izici ezifana kwesakhiwo ukuthi abayosinda okusheshayo okushisa nokuntuleka umswakama. Ngakho amaqabunga ngokuvamile embozwe ungqimba obukhulu izinwele noma wax enamathela. Zivikela izitshalo kusuka ngokweqile umswakama ukulahleka. Kukhona kwenye idivayisi. izinhlobo eziningi kweMvelo dryland buthelela amanzi kule ewugqinsi amahlamvu esinamanzi. Isibonelo ukuguqulwa enjalo ingaba njengendlela Aloe, okuyinto evame buhlanjululwe njengoba unesitshalo, kokuba okwelapha.

izimpondo

Ukuze sicabangele izici izindikimba ezilandelayo, masikhumbule ukuthi ukushintshwa leaf ezitholakala imidumba. Kuphendula ningi of them are eside futhi mncane, futhi izithelo uma sesivuthiwe zithole mass, okuyinto ayikuvumeli ukuba igcinwe sesimweni uqotho. Kodwa kuzuzisa kakhulu photosynthesis elikhiqizayo. Noma yikuphi ukulungiswa ishidi ezitholakala uphizi? Yiqiniso, lokhu amadevu. Ngakho Ushintshe platelet ngazinye ishidi oluyinhlanganisela. Ngosizo lwabo isitshalo linamathela a ukwesekwa, futhi ngenxa yalokho stem ababuthakathaka futhi mncane Itholakala isikhundla oyifunayo.

Ukuze uqonde ukuthi kungani izinso esikalini kuyinto ukuguqulwa ishidi, kubalulekile ukubhekana isakhiwo isibani. Sibheka yona esiku Ngokwesibonelo amalikhi. Isibani wayo, naphezu kweqiniso lokuthi itholakala ngaphansi komhlaba, kuyinto ukuguqulwa ingxenye zasemoyeni simila - Ukuphunyuka. Kulula ukufakazela. Escape siqukethe isihloko sesiqu, amaqabunga efihlekile. Izingxenye ezifanayo futhi babe ama. Isiqu yayo ubizwa ngokuthi i-basal ipuleti flat. Down kuwo eshiya kweqembu izimpande adventitious. Kutholwe phezu ezimbalwa izinhlobo amahlamvu. Young ahlaza begodu ukukhula kusuka efihlekile esisogwini collum. amahlamvu Juicy futhi esinamanzi uthole lolu hlobo ukuze sigcine umswakama. Ngosizo izitshalo kwakhiwa lapho isibani, komhlaba ukubekezelela nesomiso, izinga lokushisa ongaphakeme kanye nezinye izenzakalo okungekuhle. A bavikelekile umonakalo mechanical okuqukethwe kwangaphakathi ezomile isibani izikali nayo ukuguqulwa amahlamvu.

amahlamvu okuzingela

Ukuguqulwa amaqabunga futhi kuyingozi kakhulu kwezinye izidalwa. Kukhona lonke iqembu Izitshalo ezidla. Ziyakwazi, futhi ukuqaliswa inqubo ye-photosynthesis, t. E. Ingabe autotrophs. Kodwa uma izimo ukuba kwenzeke lapho, baya endleleni heterotrophic ukudla. Ngosizo amaqabunga Ushintshe Babamba izinambuzane futhi kugayeke lezo zinto. Ngokwesibonelo, isitshalo tropical Sarracenia Amaqabunga uphondo ukuthi nezinsimbi le nectaries elimnandi. Bona izinambuzane. Sasondela, isisulu iqala kwislaydi kanye emaphethelweni emgodini futhi ngivalelekile. Ngaphezu kwalokho, amaqabunga futhi ukukhiqiza imithi ekhethekile, isinambuzane Ubopha bonke osayizi. Ngenhla uphondo ishidi curled ngesimo a kwenzakalani. Le thebhu akuvumeli imvula ukuze uthole ngaphakathi, exutshwe ama-enzyme.

Ngu nokulungiswa amaqabunga lihamba ihambe futhi sundew, esemgwaqweni enisemikhawulweni goo. It ihehe izinambuzane, okuyinto ukuzitika on zwe futhi sihlupheka.

yamaqabunga efihlekile

Zonke amahlamvu kukhona izitho vegetative. Ngosizo lwabo, asexual ukukhiqizwa kabusha inqubo wenziwa. Ngokwesibonelo, uma ehlukene Ipheshana violets kusukela isitshalo omdala futhi ibekwe endaweni esitsheni yamanzi, ngemva kwesikhathi esithile, it yakha impande. Kodwa eziningi inqubo isitshalo esiphelweni lihlukile. Ngakho, ngo-Kalanchoe zasendlini kanye onqenqemeni iqabunga blade kukhona izinso, zazo amahlumela self-athuthukile. Basuke kwakhiwa cishe busuke sebukhule ngokuphelele: bubangelwe amancane amahlamvu. Imfucumfucu, bona sikhule amandla efanayo esimila omdala. inqubo enjalo yaziwa nangokuthi self-ukufanisana.

Okusho ukulungiswa isitshalo ishiya enkulu. Lezi amadivayisi ukwandisa ukusebenza futhi lula inqubo yokufunda ukuphila nesimo esithile. Ngenxa ukulungiswa ishiya izitshalo eliwumhlaba bakwazi balukhulume ezihlukahlukene sezulu esihlukahlukene, amazinga ehlukene umswakama, izinga lokushisa nomhlabathi izakhiwo. Ngaphezu kwe-photosynthesis, transpiration nokuphefumula kwezimila yeselula, leaf ukulungiswa ziwenza akwazi ukuthola ukuthi enze neminye imisebenzi ebalulekile: kuba Ukuvikelwa ezilwaneni eziyingozi futhi umonakalo mechanical, ukulawulwa negesi lokushintshisana kanye namazinga amanzi ukuhwamuka kanye nokudla heterotrophic.
