Root: mudzi mamiriro. Types mumidzi (zvipenyu)

Chimwe chezvinhu zvinokosha zvikamu chirimwa ndiwo mudzi. It kunovimbisa muupenyu inoshanda miti, rekushongedzesa, nemiti uye kunyange hwemvura Maruva. Kazhinji aboveground chikamu miti - kunongova muromo iceberg. Vakawanda rinogona riri pasi pasi. No masanga kuti midzi kwazvo nokuti basa rakakosha chaizvo basa. Ngatitorei Ukanyatsotarisa zvinoshamisa zviri muti nyika.

nemidzi

Midzi neimwe chirimwa aite zvakawanda mabasa, izvo dzinosiyana mhando nemhando, asi kazhinji kacho mabasa aya saizvozvo miti uye nokuda vazvo duku. Midzi miti uye zvimwe aboveground muti kuvabvumira kuti kuchengetwa akarurama nzvimbo kukurira mhepo nemhuka. Izvi ndezvechokwadi kunyanya miti makuru nokuda kwavo uremu uye kukwirira. The mudzi Tsika hwemvura miti kunovabatsira kuomerera nechepasi, uye kunotadzisa kuti rollover vamwe vavo.

Chimwe Zvaiitwa midzi - zvokudya. Ivo Sechipanji mvura uye zvicherwa kubva ivhu uye zvokufambisa mugwara akakwirira. Ivowo synthesize vamwe amino acids, alkaloids, uye zvimwe zvinhu zvinodiwa miti. Vamwe nemiti zvavo kuunganidza zvinovaka muviri zvakananga midzi (kunyanya starch uye dzimwe makabhohaidhiretsi). Uyewo usakanganwa zvinhu zvakadai mycorrhiza - chirimwa symbiosis pamwe notumwe. Kukosha pakutibatsira mariri midzi. The nemamiriro mudzi ndechokuti vamwe zvirimwa bereka nayo - mudzi suckers.

marudzi Midzi

Zvichienderana nemamiriro basa, izvo basa navo, pane mhando dzakasiyana pamidzi. Chokutanga - huru. Inokura zvakananga kubva mbeu kana kumera, kuti tava chikuru akabatana yose midzi. Kuwedzera huru mudzi panewo omurume. Vari aumba kubva siyana nzvimbo - pamusoro madzinde, dzimwe nguva mashizha, uye mune zvimwe zviitiko kunyange mavara. Mumwe maonero - lateral midzi. Ivo kuonekwa munzvimbo huru kana adventitious nemidzi uye mapazi kune mativi, pova itsva uye matsva matavi.

The mudzi hurongwa

All midzi, iyo ine chirimwa kuumba midzi. Zvichienderana soMupi yakasiyana midzi muupenyu wehondo yavo, pane mhando mbiri hurongwa - panozogadzirika uye fibrous. Wokutanga ine simbisa huru mudzi inokura zvikuru kuzviita. In kwakadai makirisito shamhu hwapedyo yekudyidzana zvikuru kupfuura lateral. Zvisinei, musiyano uyu unogona kuonekwa kunyanya kutanga kwekupwanyiwa kukura. Nokufamba kwenguva, mukuru lateral Midzi kutanga zvisingadzoreki kuti zvokubata chikuru ishamwari kwayo, apo zvirimwa vakuru kupfuura huru. Chinoumba Hurongwa kunoratidzwa zvikurukuru dicotyledonous zvinomera.

Chechipiri mhando iri musiyano kunyanya pakatarisana tsvimbo mudzi. gadziriro yakadaro inonzi fibrous. Zviri kwese kuti monocots uye kusiyanisa clauses yaro zhinji uye divi mapazi, ichizadza nzvimbo pazasi chirimwa. Panyaya iyi, chikuru mudzi Kazhinji underdeveloped kana husingakuvadzi undeveloped.

Root. The nemamiriro mudzi

mudzi Mumwe iri kuva zvikamu zvakawanda, chimwe nechimwe chiri kukonzera vayo nemamwe zvinhu. Chimwe chezvinhu zvinokosha nzvimbo - vachigoverana nzvimbo. It riri muromo mumwe mudzi uye anokonzera kukura kwayo pakureba. Pano kugara bereka ari zviuru masero duku. Akadaro kwacho kunoita kuti chikamu mudzi riite hapana nyore basa. Asi kugovera nzvimbo maturo pasina mudzi chivharo, riri panoperera nomumwe nomuzongoza. It chinhu intergrown akaturikidzana masero Vakagovana masero kuti kudzivirira zvokuimba kukuvara. Mukuwedzera, mudzi chivharo chinosiyanisa rudzi nebhitumini kunoita midzi muvhu.

Next mudzi chidimbu - ndichisveerera mapazi. Riri kunze nzvimbo kupesana uye kunoratidzwa muna kuti masero awo tichingotarisira kukura, kunyange zvazvo vanenge zvachose vasipo fission rikurumidze. Zvadaro pane kubvisa mapazi - nzvimbo mvura wavhomorwa kubva ivhu uye chicherwa zvinhu. Izvi nokuda vadzidzisi zvuru gumi tuduku bvudzi kuti kufukidza nzvimbo iyi. Ivo yekudyidzana kuwedzera nhamba Absorção de Água nzvimbo. Muchiitiko chino, bvudzi rimwe anoita somunhu pombi, yakayamwa ivhu zvose zvakafanira. Zvadaro pane ive nzvimbo, ndiye anokonzera chokufambisa kwemvura zvicherwa kumusoro. Uyewo, kubva pano aburuke zvinhu anokonzera rinokosha basa midzi. Chikamu ichi chakasimba zvikuru uye yakanga kubva kwaari kukura lateral midzi.

Cross chikamu

Kana iwe kucheka mudzi, unogona kuona akaturikidzana nazvo rinoumbwa. Kunotanga svuura upamhi foni imwe chete. Pasi payo unogona kuona mujinga mudzi - the parenchyma. Zviri kuburikidza zvinyama mvura yake anongoremberera pamwe zvicherwa nechikoro kuti humburumbira akabatana. Unoitisa perikamby - yedzidzo chirimwa rinenge izvo kazhinji runopoteredza conductive jira. Around ari conductive humburumbira akaronga dzine serried endoderm masero. Vane isapinda, izvo zvinoita mvura inopa upenyu pamwe zvicherwa kwira. Asi sei, zvino, nemvura anowana mukati? Izvi imhaka munhu kuburikidza mumasero anokosha riri endoderm. Kazhinji, kwakabva rekushongedzesa, miti, nemiti nourongwa hwakadaro, kunyange dzimwe nguva pane misiyano.

mycorrhizae

Kazhinji midzi miti ndiyo nzvimbo symbiosis yavo zvimwe zvipenyu. The kupfuura kakawanda vadyidzani zvinomera zviri notumwe.

Fani iyi inonzi mycorrhiza, iro rinomirira "gribokoren". Zvakaoma kutenda, asi akawanda miti kunotsamira pane kubatana mycelium rinobereka. Familiar kwatiri birches, maples uye miouki akabvisa zvakawanda zvinobatsira kubva symbiosis ichi.

Kana kuwadzana midzi mycelium iri vakatsinhanisa, sezvamakaropafadzwa mycelium anopa muti kuchikosha zvicherwa, makabhohaidhiretsi mu kudzoka. mberi ichi shanduka kwakabvumira mhando dzakawanda zvinomera vanogara ezvinhu kukodzera nokuda mhuka dzavo. Uyezve, vamwe nemiti havana kuvapo zvachose dai zvisina mycorrhiza. Kuwedzera symbiosis pamwe notumwe vane pamwe chete utachiona, iyo inoshandisa mudzi rinobatsira. mudzi mamiriro hazvisi akasiyana dzose isu. On zvichibvira kuona nodules inogarwa utachiona chinokosha kuti kupa muti mumhepo senitrogen.

mhedziso

Chimwe chezvinhu zvinokosha zvikamu chero chirimwa ndiwo mudzi. mudzi mamiriro iri Zvakanakisa wakanyatsokodzera nokuda mabasa kuti anoita. The midzi - zvinoshamisa nomazviri kudyisa zvinomera. Pasina siyana tiwane dzenzvimbo vanodavira kuti muti anosanganisa mauto okudenga napasi. Ake zvemuchadenga chikamu absorbs chezuva uye midzi kuwana zvinovaka muviri kubva muvhu. Kukosha mudzi hurongwa haisi pachena, sezvo pfungwa Anobata aboveground chikamu chirimwa: mashizha, hunde, ruva, hunde. Root panguva anoramba mumimvuri, nokuzvininipisa kuzadzikisa kwavo basa unokudzwa.
