Muenzaniso wehunde yemuti une dicotyledonous

Tsananguro pfupi:

• Kushandisa: Yakakodzera chero ani zvake anofarira anatomiyumu, ukoti, physiology. Nzwisisa nhengo dzakasiyana dzemuviri wemunhu nenzvimbo dzadzo. Yakakodzera kwazvo kudzidziswa kwevana, chipo chakakwana chevana.
• Masero e epidermal akazara uye akaumbwa ne keratin, uye masero e cortical ane nyanga dzakakora pedyo ne epidermis uye akaita semadziro. Mitsempha yeropa inoratidza phloem fibers, primary phloem, formation uye primary phloem, formation uye primary xylem. Inzira isingawanzo shandiswa yekudzidzisa biology.
• Muenzaniso uyu wakatorwa kubva kudivi resunflower rine tsinde remiti rakasiyana. Muenzaniso uyu wakachekwa zvakareba uye zvakachinjika, uye chikamu chawo chakachinjika chingangoita 2/3 yetsinde. Rutivi rumwe rwechikamu chakachinjika runopfuura nepakati pemwaranzi yemedullary uye rumwe rutivi runopfuura nepakati petsinga. Zvinokutendera kuti unyatsobatanidza dzidziso nemaitiro ekudzidzisa kuti unzwisise.
• Modhi iyi yakagadzirwa nepurasitiki yepolyvinyl chloride (PVC), inodzivirira ngura, yakareruka, uye yakasimba. Yakanaka pakudzidzisa kuchikoro, pakuratidza zvinhu zvekudzidza, uye pakuunganidza zvinhu, uye ichavewo chinhu chakanaka pakushandisa murabhoritari.
