Annual zvindori - nayo cambium? mamiriro fukntsii

Cambium - a rejira, riri pakati matanda uye phloem. Ndepapi parinotaura zvinobva? It unovapo kubva procambium - vascular mwanda. Inowanika madzinde, midzi zvinomera.

Pakutanga, cambium zvinomera vakawana chete vascular mwanda. Izvi mhando inonzi chisote. Zvadaro, zvinyama anoumba marongera pakati medullary mwaranzi, akaronga pakati matanda. Izvi rworudzi danda inonzi cambium.

The akaturikidzana vanoumba remubatanidzwa cambium danda, pova chete-rukoko mhete. With kukura zvinomera anoumba matanda itsva uye axial zvomukati vanotanga kukura ukobvu, zvichiumba akaturikidzana itsva huni. Ndiro huru kushanda cambium. Irreplaceable.

In yechando cambium avete, saka kukura zvinomera zviri ukobvu panguva kutonhora hakuitiki. Nokuda kuchinja kuitika hunde yacho chirimwa uye nguva dormancy munguva yechando pagore zvindori vari aumba.

Basa, mamiriro

Cambium - uyu rejira inokosha, pasina iro kukura muti ukobvu hazvibviri. masero Its - prozenhimnye. Vane elongated chimiro uye bevelled kumugumo. Prozenhimnyh kureba kwazvo upamhi sero kakawanda. In longitudinal muchinjikwa-sectional rectangular chimiro ari kuchengetwa.

Cambium - ndivo masero kuti vane kunzwisisa maumbirwo. Vari chiri mukati musimboti, cytoplasm uye organelles. The chinoshamisa ndechokuti anononoka kufamba kuitika munyika cytoplasm. Nokukurumidza kunobva mwaka. Nechepakati chikamu sero ndiwo musimboti. Zvinonzi ichazivikanwa noku elongated chimiro. Masero vaigona kudya chirimwa zvakachengetwa muviri. Vanopinda muchitokisi plasma.

kupatsanurana

Rinotevera nguva. Cambium - kamuri aigona kugovera. Zvichiitika nokuda cytoplasm.

cambium masero vanokwanisa kugoverana chete polar. Rimwe divi - kuumba matanda, uye kuno rumwe - the omuti hwomuti. Hazvibetseri fission kunoitika disproportionately. Naizvozvo, muti omuti rine zvishoma pane huni. Kana sero nekupesana akaenda proportionally, pashure unonyatsoruramisa huni nemakwati uye vaizova zvakaenzana.

Munguva weboka rimwe sero rinokamukana kupinda maviri. Ipapo mumwe mutsva zvinhu anova mubereki muchitokisi, uye mumwe - zvakare chakakamurwa nepakati, akatendeuka ari phloem kana huni. Kwokupedzisira Kuchinja kunoenderana chikamu ripi chirimwa pedyo divisible masero.

Munguva weboka huni rakachengetedzwa kurutivi muzinda pabazi. A Cork - kusvikira kumucheto.

shanda

Zvino vamwe kuita. Zvinowanikwa iri hunde cambium anoita basa rokudzidzisa. kugona ichi rinobva yakasiyana nemamiriro rukoko. elongated masero vake matete anoshongwa kunogona kugovera uye kukura. Nemhaka iyi hunde chirimwa richikora.

zvindori pagore

Munhu wose anoziva kuti miti vane zvindori wepagore. Kwavari iwe unogona kusarudza makore vangani chirimwa. Mugore rimwe denderedzwa kuumbwa, kureva. E. Annual mhete. Zvinonzi akaumba cambium iyo kunopa fission hunde kukura ukobvu.

Miti muchikura okunze, weboka masero ayo kunotanga mangwanani chitubu uye inoguma vari kuwa. Uchimuka, muti anotanga kukura nokushingaira. Panguva ino, iyo cambium ane masero guru, iro pakasvika kupera kwechirimo kuva yakatetepa, asi chiine nevamwe. Somugumisiro weboka iri paumbwe rin'i gore negore. Kuburikidza Ukobvu anogona kutongwa pamusoro kukura wamatanda pagore. Mumwe mhete wepagore chinosanganisira zhizha nechando rukoko. Vari kusiyaniswa ruvara: rinobwinya - ichi zhizha, uye rima - muchando.

Kana vachigoverana cambium masero vanoumba matanda omuti. Wokutanga anoita mashandiro stocking uye nemakwati - anodzivirira. zvikamu izvi zviri chirimwa zvakaitwa kubva mamwe marudzi masero. Munguva Mwaka wokukura nechimwe chine maatomu akafanana anozadzisa yaro chaiyo muchinangwa kukura chirimwa.

Muchidimbu, cambium kunokosha chirimwa tishu. Vanenge havana kunge zvaiitikawo pasina iye.
