Ndezvipi vegetative nhengo zvinomera

Kukwidziridzwa zvinomera panyika pamwe nhamba aromorphoses (Qualitative shanduka kuchinja), mumwe wakanga ari kwaita kusiyaniswa nhengo - nhungirwa mudzi. Izvi vegetative nhengo zvinomera zvinobatanidzwa zvose zvinokosha dzinotsanagura zvimwe pane zvepabonde kubereka (anokonzera nayo rokubereka nhengo) muviri anokosha. Chavainyanya mabasa vari kudya kunovaka uye muviri pamwe kunze nyika. Plant upenyu panguva imwe chete munharaunda mbiri - mhepo uye lithosphere - chokuita kudikanwa kutanga, uye ivhu, uye mhepo. Mumwe nomumwe vezvenhau ava anosangana chaidzo nhengo.

Vegetative nhengo kuvakuru zvinomera zviri rakakamurwa pachivande (midzi) uye aboveground (matavi). With chirimwa mudzi yakatarwa muvhu, tibatsirwe unyoro uye zvinovaka muviri pauri, kuunganidza navo uye zvifambiswe kutiza, uye mune zvimwe zviitiko akaita vegetative kupararira. Modified midzi mudzi tubers (Jerusalem artichoke, Dahlia), mudzi zvirimwa (beets, makarotsi), negadziriro yeparutivi-mudzi (pandanus, banyan), zvemuchadenga Midzi (orkideat), kufema Midzi (taksodium), Kuziva Midzi (Ivy). Pakutanga, izvi vegetative nhengo vakasikwa kuti chicherwa muviri, asi mune zvimwe zviitiko yavanobata zvikuru kujairika zvinhu. Aerial midzi vamwe orkideat kuunganidza mumhepo mwando, apo taksodiuma kuita kufema ushande. epiphytes zhinji vanorembera mudenga, nemhaka kuvapo chlorophyll vane mutema ruvara uye urimowo photosynthesis.

The chikuru kushanda kupukunyuka - kabhoni simba. Kusiyana mudzi, ndiko kunzwisisa nhengo ina yoga interconnected zvikamu - hunde, mashizha uye atwo. Maererano yokutiza uyu dzimwe nguva sechinhu chinokosha gadziriro dzine kuparadzana asi dyidzana zvikamu. Mune dzimwe manyuko unogona kunyange kusangana kutaura kuti hunde, mashizha uye atwo - ichi ndiko vegetative zvomukati zvinomera. Matavi vari vegetative (vachiwaridza) uye rokubereka (akatakura mashizha, maruva nemichero).

Kupukunyuka muzasi ndiyo hunde, iyo anoita kubatana pakati nemidzi uye mashizha, inotsigira kuti rokubereka zvomukati uye anoita chokufambisa mvura ukaparadzawo muviri. Dzimwe nguva nhengo rinobatanidzwa vegetative kubereka, uye pane muduku - uye photosynthesis. The jira kushanda sezvo photosynthesis, transpiration, gasi Exchange, kuchengeta zvinhu uye micropropagation. Itsvo - iri wokugaya retsono.

Panguva ontogeny (munhu kukura) vegetative chirimwa nhengo anogona kumbotambudzika vachinje marongerwo (metamorphosis). Izvi zvingava nokuda chaizvo okunze zvinhu vapone umo dzimwe nzvimbo miti vachinje yapakuvamba mabasa. Somuenzaniso, muna dzisinganayi nzvimbo kwemarudzi mazhinji ezvinhu mashizha tinoshandurirwa minzwa kana chikero kuderedza kwemvura pamusoro. At hunde Succulents (African Euphorbia, cacti) dzinde dzine - nayo vodozapasayuschy uye photosynthetic nhengo, iyo iri axils mashizha undeveloped kukura mapfupi nhungirwa vane Masvinga yeminzwa. Mbeswa dzinobata nekudya tupembenene (drosophyllum, Pinguicula, sundew) mashizha dzikwanise misungo chaiye, izvo pusa kana kushingaira nzira kunombata nezvipembenene. Vamwe Mizambiringa (Passiflora, mazambiringa) zvemuchadenga awo tinoshandurirwa vaikwira nhengo (tunonzwa) - iri rine metamorphosis.

Vegetative nhengo zvinomera zvinobatanidzwa asexual kubereka, inova paumbwe wechidiki muviri kubva chero chikamu mubereki. nzira iyi kupararira kuri ubiquitous musango uye ari kushingaira kushandiswa chirimwa. Muchiitiko chino, kushandiswa se specialized nhengo (midzi, Mabumba, tubers uye stolons) uye choruzhinji (madzinde, mashizha).

In nechepasi miti vegetative nhengo ndiwo muviri wavo wose, somuenzaniso, kuti mycelium yacho chakuvhe.
