Imodeli ye-Dicotyyeledonous stem stem

Incazelo emfushane:

• Isicelo: Kufanelekile kunoma ngubani onentshisekelo ku-anatomy, ubuhlengikazi, physiology. Qondisisa izinhlaka ezahlukahlukene zomzimba womuntu nezikhundla zazo ezihlobene. Ilungele kakhulu imfundo yezingane, isipho esiphelele sezingane.
• Amangqamuzana e-epidermal agcwele kakhulu futhi aqokiwe, futhi amaseli we-cortical anezimpondo ezinophondo eduze kwe-epidermis kanye nodonga olubunjiwe. Izinqwaba zemithambo zibonisa i-phloem fibers, i-phloem eyisisekelo, ukwakheka kanye ne-phloem eyisisekelo, ukwakheka kanye ne-xylem eyinhloko. Ingabe usizo olungavamile lwe-biology lokufundisa
• Imodeli ithathwe kwi-dicotyledononuus herb squem sunflower. Imodeli isikwa yinde futhi iguqukile, futhi isigaba sayo esiguqukayo sicishe sibe ngu-2/3 weStem.One eceleni kwesigaba eside esidlula emisebeni ye-medullary futhi uhlangothi olulodwa ludlula esixukwini semivimbo. Ikuvumela ukuthi uhlanganise ngempumelelo i-Theory ye-Workory ngokuthuthukisa ukuqonda
• Imodeli yenziwe nge-polyvinyl chloride (PVC) yeplastiki, okuyi-cororious engamelana nokukhulisa, futhi inamandla aphezulu.
