Imodeli yesiqu sesityalo esinee-dicotyledonous

Inkcazo emfutshane:

• Ukusetyenziswa: Ifanelekile kuye nabani na onomdla kwi-anatomy, ukonga, i-physiology. Qonda amalungu ahlukeneyo omzimba womntu kunye nezikhundla zawo. Ifanelekile kakhulu kwimfundo yabantwana, isipho esigqibeleleyo kubantwana.
• Iiseli ze-epidermal zixinene kwaye zifakwe i-keratin, kwaye iiseli ze-cortical zineempondo eziqinileyo kufutshane ne-epidermis kwaye zimile njengodonga. Ii-vascular bundles zibonisa ii-phloem fibers, i-primary phloem, ukwakheka kunye ne-primary phloem, ukwakheka kunye ne-primary xylem. Sisixhobo sokufundisa i-biology esingaqhelekanga
• Le modeli ithathwe kwisiqu se-sunflower esine-dicotyledonous herb. Le modeli isikwe ngokwe-longitudinal nangoku-cross, kwaye icandelo layo eli-cross limalunga ne-2/3 yesiqu. Icala elinye lecandelo eli-longitudinal lidlula kwi-medullary rays kwaye elinye icala lidlula kwi-vascular bundle. Ikuvumela ukuba udibanise ngokufanelekileyo ithiyori kunye nokuziqhelanisa ukukhuthaza ukuqonda.
• Le modeli yenziwe ngeplastiki ye-polyvinyl chloride (PVC), ekwaziyo ukumelana nokugqwala, ilula, kwaye inamandla aphezulu. Ilungele izixhobo zokufundisa zesikolo, isibonisi sokufunda, kunye nezinto eziqokelelweyo, kwaye iya kuba longezo oluhle kakhulu kwizinto zakho zelebhu.
