Chii pamudzi chirimwa?

Chii mudzi? Chinhu chakakosha zvikuru chirimwa nhengo kuti rinopa kukura kwayo uye basa. The chidzoke womuviri uyu ave chokuita padariro kukura nemiti pepasi.

Root - chikamu pevhu pamusoro chirimwa, chine apical kukura uye ane TOUR marongerwo.

Huru mudzi mabasa vari:

• chinotsigisa - kureva, bata muti muvhu;
• rokutora uye - kugamuchira kubva pasi mvura uye zvicherwa zvinhu zvifambiswe kuburikidza xylem (mvura kuitisa zvinyama) vose aboveground chirimwa pagondobwe kugadzirwa pakunyudutsa photosynthesis.

Also synthesized mune zvemuchadenga zvikamu chirimwa Organic zvinhu, uyewo pamudzi mahormone, amino acids, alkaloids, et unto., -wedzera mairi uye kugoverwa muviri. The mudzi ndeimwe nhengo vegetative Mashoko zvinomera.

Pamwe tsanangudzo chii mudzi, nguva dzose rinowanika pfungwa yacho midzi, iyo chakaumbwa zvose midzi nezvinomera uwandu hwezvinhu zvose zvabatanidzwa.. Kusiyanisa chikuru, adventitious uye lateral midzi.

Huru (kana chikuru) mudzi unowana zvayo budiriro iri richiri embryonic midzi. In maruva zvinomera gymnosperms chikuru mudzi ndiwo mukuru, ane rwakakura kukura uye zvakanaka geotropism (kureva kupa yakarurama nokuda kukura zvinomera).

Adventitious midzi chesekondari uye kukura kubva madzinde vakwegura midzi, kana mashizha.

Lateral nemidzi kukura kubva huru uye chishongedzo.

The Mudzi mhando mamiriro vari chinoumba kana fibrous. At chinoumba mudzi ezvinhu chikuru mudzi kunoratidzirwa zvakasimba. Kwakadaro hurongwa vane vakawanda dicotyledonous zvirimwa (semuenzaniso makarotsi, voikukkien, visi, sunflower). Kana fibrous midzi kukura huru mudzi akaratidza zvishoma, hazvina kumira pakati adventitious midzi (semuenzaniso, valerian mudzi, psyllium, rye). Ichi midzi kwese zvikurukuru monocots.

The womukati nemamiriro midzi

Chii mudzi, kubva nemaonero ayo womukati mamiriro? At payo ari kuitisa midzi zvinosanganisira nomusero sepombi uye nemidziyo. Huchaunza mvura chokufambisa midziyo pamwe chete ichiputswa zvinovaka muviri kune zvemuchadenga nhengo bvudzi midzi. Nesefa sepombi, nekusiyana, iri kuendeswa kubva Organic mhinduro nemiviri yenyika kuti masero mudzi. Masero edzidzo mudzi munyama (cambium) iri akaramba yakakamurwa uye anopa ichi mudzi kukura ukobvu.

Chii mudzi, uye zvose zvayo chikuru mapazi zviri pachena kuoneka longitudinal chikamu.

Mudzi chivharo chakaumbwa yokunamisa jira uye zvinovhara mudzi chakaderedzwa mutengo, kudzivirira nayo sezvo chivharo kubva kukuvadza-siyana. vamwe basa racho kusimudzira mberi midzi muvhu.

panoparadzana mapazi iri pakarepo pazasi mudzi chivharo uye ine masero zviduku Micheka zvedzidzo kuti zvinopa zvavo zvachose panoparadzana mudzi kukura.

Munotatamura mapazi aumbwa chete kukura masero vaduku chaizvo, akatambanudza muna longitudinal negwara uye nokudaro achiita mudzi kukura pakureba.

Kana muti nokungwarira kuchera, unogona kuona kuti midzi entwine ivhu nezvimedu, chikamu ichi anonzi kubvisa nzvimbo. Zvinonzi nokufukidzwa mudzi vhudzi, ane basa iri muchayamwa mvura pamwe muviri. Nebvudzi zviri nebhitumini pemvura.

Pamusoro kubvisa kunzvimbo mapazi chakaumbwa imwe Mucheka conductive uye anoumba dzakawanda mudzi urefu. For midziyo Ungadzura mudenga achitevedza hunde uchifamba mvura uye zvicherwa, izvo yakanyauka zvakananga mazviri.

Vamwe midzi miti inogona kuchinjwa nokuda chidzoke kumuvengi ezvinhu nokuda kwekuwedzera zvinomera uye kupa pekugara kwavari.
