Vakuru, vachipinda mumatambudziko ezuva nezuva, vanorega kuteerera nyika yose, asi vana zuva nezuva vanoshamiswa nemamiriro avo. Uye inoshanda sei? Uye nei? Uye nei? Uye saka zvakakosha? Izvozvo chete hazvifariri zviduku zvishoma! Uye kana iwe ukapfeka zita rinozvikudza raamai kana baba, nokukurumidza kana kuti gare gare iwe unenge uchinyatsonzwa mubvunzo uyu: "Sei mashizha achiita zhizha mukuwa?" Sezvo mubvunzo pachawo usina kunyanya kuoma, ndicho chimwe chezviratidzo zvekuvhura , asi zvinenge zvichireva Zvimwe, izvo zvinofanira kupindurwa zvakadzama uye zvinonzwisisika. Zvakanaka, ngatiedzei kuzviita!
Uye nei mashizha achichinja?
Mumazuva echando uye zhizha mumapepanhi ose pigment chlorophyll inorarama, iyo ine ruvara rwemavara. Iyo yakawanda yeklorophyll inogadzira mashizha pamiti yakasvibirira. Iyi pigment inodiwa nemuti kwete kungofadza chete, asi kune zvokudya zvinonaka, nokuti chlorophyll inogona kushandisa masikati kuti ichinje carbon dioxide nemvura muzvinhu zvinovaka. Saka, nokuda kworuva ruvara rwechando rwechando, muti unokura uye unowedzera. Asi pane nguva inouya apo zvisikwa zvinogadzirira nguva yechando, apo basa rayo rinokosha rinomiswa, mashizha achiita zhizha - izvi zvinoitika muvhu. Mashizha ari kuwana mvura shomanana, chlorophyll inoparadzwa zvishoma nezvishoma, uye mbeu dzinorasikirwa nemaruva avo. Zvinonakidza kuti chlorophyll inonyanya kuparadzwa nezuva, saka nguva iyo mashizha anotanga kuchinja masikati mukuwa hakuiti nguva dzose panguva imwe chete. Mumvura yakaoma, yakajeka yekupera, mashizha anochinja mavara nekukurumidza, uye mumvura yekuvhuvhuta inonaya vanogara vemavara kwenguva yakareba.
Uye nei avo vane ruzha, uye avo vatsvuku?
Mwana anonyatsoteerera anozobvunza kuti nei mamwe mashizha mumiti achiita zhizha, vamwe vatsva, uye vamwe vachibva vadzoka. Mhinduro yacho iri nyore. Ichokwadi ndechokuti kuwedzera kune chlorophyll, mashizha emiti anosanganisira mamwe mavara, asi nekuda kwegorosi rinowanzosaoneki. Sezvo chinyorwa chlorophyll chichidzoka, mamwe mavara anoonekwa:
- mashizha matsvuku anowana ruvara rwavo semugumisiro we "basa" yemurimi pigment xanthophyll;
- mashizha emaruva akaisa pamapfekete avo ekuvhura, apo iyo pigment carotene inowoneka, iyo, nenzira, inozivikanwa kune wese nemuchena wakachena wearroti;
- Mashizha matsvuku akawana ruvara urwu rusina kutarisirwa nekuda kwezvimoto Anthocyanins;
- mashizha mashoma - uyu hausi kuiswa kwevhudzi, asi ruvara rwemajeri masvingo egashizha, rinowanikwa apo mamwe mavara aripo anoonekwa aripo.
Uye nei mashizha achiwa?
Kana tichitaura pamusoro pekugadzirwa kwemashizha, ipapo inogadziriswa yakajeka - muvhuvhu, kana mashizha achiita zhizha, kuparadzanisa kwemajeri kuno rumwe rutivi rwemashizha, izvo zvinonzi cork layer. Zvishoma nezvishoma, kupatsanurana uku kunokonzera kubatana pakati pemuti uye mashizha. Rinoramba richimirira kuti mhepo ibuze uye pepa iri pasi. Pabazi riri munzvimbo yemasasa rinosiya ruvara ruduku runopfurikidza chidziviriro chekuchengetedza cork, zvinoreva kuti pamuti ndiyo nguva isingarwadzi. Kana iwe uchizvibvunza kuti nei mashizha achiita zhizha ndokuwa,
