2026 biology talkshow:植物根部中柱構造的奧秘 (選修生物II)

將植物根部的中柱（Stele）喻為精密的「地下物流總部」，詳盡解析維管植物如何透過這套核心構造在陸地環境中生存。首先探討由內皮層與卡氏帶組成的安全過濾系統，解釋植物如何利用木栓質的物理特性來篩選養分並產生根壓。接著分析具備強大分生能力的周鞘，以及木質部與韌皮部在單、雙子葉植物中截然不同的排列策略，展現演化在運輸效率與力學支撐間的權衡。最後介紹維管形成層如何驅動次生生長，說明這套沈默的工程學奇蹟是如何支撐起生命結構的擴張與延續。聽完後可以自主進行線上測驗，檢視學習成效喔~(需要登入gemini) 測驗網址  https://gemini.google.com/share/2684ab5b7823 Powered by Firstory Hosting
