Mudzi vhudzi - nayo ... rutina pamudzi vhudzi

Complex metabolic kuchaita miti anotsanangura rinokosha maumbirwo dzavo nhengo dzomuviri: mudzi, hunde, shizha, inonzi vegetative dzomuviri. Ivo ndivo photosynthesis, transpiration, osmosis. In neKwayedza tikadzidza marongerwo uye mashandiro miti yakadaro zvinhu sezvo mudzi vhudzi. Ava zvivako zvinokosha kuti tizive kuti Absorção de Água nemvura chicherwa munyu kubva muvhu.

Root - the vegetative muviri mbeu miti

The pevhu Chikamu gymnosperms uye maruva miti chinomiririrwa mhando mbiri pamudzi maitiro: Musimboti uye fibrous. Zvinosanganisira huru, divi, paranasal (mu monocots) pamidzi uye vakawanda zvivako zviduku pamwe zita - mudzi vhudzi.

It outgrowths rhizodermis (rizodermy) hunomiririrwa masero kuroorwa. Vari kunzi "trihoblasty". Kutsigira uye achiita mashandiro dzekuchengeta Organic zvinhu, Absorção de Água uye chokuwanziridza (anonzi suckers vane Cherry, the willow), mudzi uye zvisina kunanga mumabasa metabolic pezvakaitwa akadai transpiration, afemeruke, photosynthesis.

kubvisa mapazi

Huru mudzi ane kunzwisisa anatomical chimiro, uye zvikamu zvaro siyana mabasa akawanda mabasa. Panyaya iyi, dzinonzi zvikamu. Pahwaro mashandiro mudzi vhudzi (yepamusoro tensile mugove vanobatanidzwa kukura mapazi) uye nesumbu protuberances kufukidza jira. Nzvimbo iyi inonzi kubvisa nzvimbo. It yemakomo rimwe kusvika kumatatu masendimita. Munharaunda iyi ingabva 200 kusvika 1500 uye vakawanda elongated rhizodermis masero. Vane pfupi-akararama: kubva maawa mashoma mazuva 20, uye ipapo akafa. Panguva iyoyo pakati rizodermy zvivako zvitsva zviri aumba. Keji midzi bvudzi neVadzidzi pasi, anokwanisa Absorção de Água mvura mamorekuru uye ichiputswa munyu muchimiro yavaibvisa, kuiisa chlorine, magnesium, nitrate anions, nitrite uye iine acid phosphate.

Rhizodermis nemamiriro ayo mamiriro

Izvi chirimwa rinenge rinoreva boka chikuru meristems. Nechekuita fission masero zvinopa kwayo nokuumba zvinhu zvakadai mudzi vhudzi. Izvi zvinoitika muna rokunze rukoko pamusoro jira dzidzo pamudzi - fellogene. Akaumba munguva kukura mwaka rizoderma anofa. Munzvimbo yayo vakaumba masero vaduku periderm - yechipiri unhani jira kuti haakwanisi kubvisa ivhu mhinduro. New bvudzi mudzi, mashandiro iyo - the Absorção de Água nemvura chicherwa munyu, aumba kubva overlying mugove rhizodermis.

Mashandiro anoita mudzi vhudzi

zvivako izvi vari aumba kubva miganhu rizodermy uye vanomirira chimwe chikuru meristem masero vanokwanisa Absorção de Água ivhu mhinduro. Nokufamba kwenguva, vanokweverwa, uye sero Kamudzira anova anokwanisa inoyerera mukati zvose hypotonic uye zvikuru kuramba munyu mhinduro. Paaiita fetiraiza, zvakadai senitrogen uye potassium muvhu kunowedzera wevasungwa pamusoro Ammonium ions, potassium nitrate Ion. Richiwanika muchirimo, sezvo yava yakanakisisa nguva kushanda fetiraiza kwakadai. Soil mhinduro chine mhando pamusoro Vakaverengwa ions vari cytoplasm trihoblasta chinopinda nokuda pusa diffusion.

Autumn phosphorus fertilization, zvinotora nguva yakareba wokuparadza, kukonzera Absorção de Água pamudzi bvudzi Ion phosphate anions uye metaphosphoric acid. Pachatanga muto kuyerera mukupera February - mangwanani March, rinenge vhoriyamu rose masero rizodermy vakazadzwa vacuoles, musimboti zvava pamusoro mudzi vhudzi. The chaizvo chete Sero anokwanisa secreting mamorekuru ose Organic acids: oxalic, malic. Ivo ichiputswa manyowa nezvimedu, kuwedzera Absorção de Água rikurumidze. Nezvekugadzirwa mudzi vhudzi nokukurumidza zvakakwana. Pasinei pfupi upenyu, vanokwanisa kupinza yakawanda ivhu mhinduro. Somuenzaniso, Woody chirimwa kubvisa nzvimbo anenge 120 kusvika 640 mamita ^2.

Chii trihoblasty

Kare, takadzidza marongerwo uye zvinhu zvikuru mashandiro anoita chirimwa tishu machira. Inoitwa chete rukoko masero anonzi rhizodermis, avete wechiduku lateral midzi, kukura kubva huru kana adventitious midzi. Root vhudzi - ichi zvinyama outgrowths yokunamisa anomiririra zvikuru elongated marongerwo. Tinofanira kurangarira kuti zvose masero rhizodermis - pluripotent, kuti anokwanisa rokuumba mudzi vhudzi. Asi ivo vari aumba chete kubva trihoblastov - rhizodermis miganhu vane chimiro nemaziso anorovera.

Bemhapemha zvinyama mhosva paumbwe trihoblastov ane cytologic zvechiratidzo chacho, mumasero yayo havana cuticle uye gobvu rusvingo cellulose. The cytoplasm rine vakawanda organelles kuti synthesize ATP mamorekuru - the mitochondria. Ndivo zvakakodzera nokuti Absorção de Água nemvura chicherwa munyu kunoda simba. Trihoblasty dzinewo stomata - kufukidza zvinyama zvinhu anokonzera pezvakaitwa kufema zvinomera uye transpiration - mvura kwemvura.

Sezvo munyu zvinogadzirisa zvinopfuura chirimwa Midzi

Trihoblast uye zvichiitika pauri bvudzi mudzi, inova Zvaiitwa - the Absorção de Água nemvura chicherwa munyu kubva muvhu, anogona kunzi sechinhu osmotic hurongwa. Kushaya yakaoma muchitokisi rusvingo uye Kamudzira elasticity hwezvekukurukurirana chokufambisa pamusoro mamorekuru kubva kwokunze ezvinhu mukati cytoplasm. In dzakananga organelles mudzi bvudzi - vacuoles kuunganidza hypertonic zvinogadzirisa kuti shuga, fructose, malic, cucumber uye oxalic acids.

Uye Kamudzira uye tonoplast masero vari zvokusarudza semipermeable. Naizvozvo, ivhu mhinduro, kunyange zvishoma pfungwa yokushanda pane muchitokisi muto, maererano nemitemo osmosis chinopinda mudzi vhudzi. Water zvinogona zvingaitwa kuuya kubva muvhu kupfuura mufananidzo uyu tonoplast, uye osmotic zvinogona pazasi. Water uye chicherwa munyu trasportiruyutsya masero ari bvudzi mudzi xylem. Izvi Mucheka conductive dzichiumbwa chirimwa midziyo - kana trachea tracheids. Maererano ivhu mhinduro chinofamba vakasimudza hunde kune mashizha nezvimwe chirimwa zvikamu.

Swordplay uye kukosha kwayo

Kuwedzera kubvisa nzvimbo midzi, unofanira kuita kuti kuwedzera uwandu lateral midzi. rhizodermis dzavo rine trihoblasty uye vaunze imwe mudzi vhudzi. Kushandisa ichi zvokuimba nzira proschipyvaniya mudzi chakaderedzwa mutengo achiparadza kugovera mapazi yaiva pamusoro mudzi chivharo. Zvakanyorwa kunzi sparring. nzira iyi kunomutsa kukura divi zvikamu, iyo anovandudza vakawanda mudzi vhudzi. Kukura huru mudzi pakureba hunoguma. Most nzvimbo kubvisa mapazi kunobatsirawo pamusoro chirimwa kukura, ichiwedzera ayo yauinayo uye chinhanho.

Munyaya ino isu akaongorora STRUCTURAL zviri Absorção de Água mapazi pamudzi angiosperms uye akaziva chii mashandiro mudzi vhudzi, kukura kubva rhizodermis.
