Unoda here kuziva kuti ndeapi mativi edanda remuti? Pasina kupokana, zvinonakidza kwazvo kuziva zvakawanda nezvezvirimwa izvi, zvinovimba nenhamba huru yemhuka - kusanganisira isu vanhu. Pamwe dai isu tese takadzidza zvikamu uye mashandiro ezvirimwa, nyika yaizosiyana, asi uyu ndiwo mumwe musoro watisingabate pano.
Tevere ini ndichaenda kunotsanangura izvo chimwe nechimwe chezvikamu zvacho, uye kuti zvinobatsira sei pamiti.
Chii chinonzi muti?
Mutsva wakamera. Iwo ma cotyledon maviri (akazara, mashizha akapusa) anogona kusiananiswa.
Muti Ihwo huni huni hunosvika hushoma hwemamita mashanu pakureba (vamwe vanoti 5 kana 6), uye iwo matavi kubva kune mamwe mamita pamusoro pevhu. Mashizha anogona kuve anodonha; ndiko kuti, vanowira pane imwe nguva yegore (zhizha kana matsutso / nguva yechando), inogara (zvinoreva kuti vanowa asi zvishoma nezvishoma mukati megore), kana semi-kupera, ndiko kuti, vanowira zvishoma.
Kune michero yakawanda yakaita semuti asi isiri iyo.. Muenzaniso wakajeka miti yemichindwe. Kazhinji, kunyangwe mumabhuku egadheni, ivo vanokuudza kuti iyi miti zvakare, asi ivo havana kana basa nazvo, nekuda kwechikonzero "chakareruka" chekuti ivo monokoti, kwete madiki. Mashoko iwayo anorevei? Mabvazuva:
- Monocots: painenge ichikura, mbesa dzine rimwe cotyledon kana shizha rechinyakare. Zvimwe kunze kweizvozvo, ivo havana cambium, zvinoreva kuti havagone kuramba vachikura mukukora. Mienzaniso: Asparagus, Pandanus, Pa, bulbous, uye zvese chanza, pakati pevamwe.
- Dicotyledons: ndeaya anoti kana uchimera une maviri kana anopfuura macotyledon kana mapepa echinyakare. Vane cambium, saka hunde dzavo dzinogona kusvika pa… tsime, kudzamara geneti rikavaudza 🙂. Mienzaniso: yese miti, shrub, maruva emvura, Ceratophyllum, Amborella, nezvimwe.
Ndezvipi zvikamu zvehunde yemuti?

Zvino zvatave kuziva zvishoma pamusoro pemapoka makuru maviri ezvirimwa uye nehunhu hwavo, inguva yekudzidza zvakawanda nezve miti. Zvikamu zvehunde yawo ndeinotevera:
- Cortex: iyo yakatenderera, uye kunyangwe iri yakaoma, iri zvakare yakaoma. Inoumbwa nechikamu chemukati chakagadzirwa nemasero mapenyu, uye rukoko rwekunze rwakagadzirwa nemasero akafa.
- Cambium: iyo yakatetepa nhete panogadzirwa maseru matsva, ayo anotendera kuti muti ukure nekukura kubva pagore kusvika pagore.
- Xylem: inozivikanwa sesapwood. Iyo dura inoumbwa netiweki yemasero ane basa rekutakura mvura uye zvinovaka muviri kubva mumidzi midzi kusvika kumatavi nemashizha. Iyo huni diki, yakanyanya, uye zvakare yakapfava.
- Mwoyo: Inoumbwa neakafa xylem, ndiko kuti, nemasero akafa ayo akamboumba xylem. Iyi huni ndiyo yakaoma kwazvo, uye nekudaro inopa rutsigiro uye simba.
- Marrow: inzvimbo diki yemasero mapenyu ari pakati petrunk. Kubudikidza naro, izvo zvakakosha zvinovaka muviri zvinotakurwa. Inodzivirirwa nehuni hwakaoma kwazvo.
- Medullary mwaranzi: iwo mwaranzi iyo inobuda mukati meiyo pith, uye kuburikidza iyo sosi inotakurwa.
Ndinovimba zvanga zvichikufadzai 🙂.
