2026 biology talkshow:頭化演化與極簡生存之道-扁形動物門 (國中生物 單元九)

from 雷比特生物空中講 · host 雷比特老師

深入介紹扁形動物門在生物演化史上的關鍵地位,強調其作為首批發展出兩側對稱與三胚層構造的先驅。由於缺乏循環與呼吸系統,牠們透過扁平的身體極大化表面積,以維持生存所需的氣體擴散效率。詳細剖析三大類群:具備驚人再生能力的渦蟲、擁有複雜多宿主生活史的吸蟲,以及完全捨棄消化系統的極簡寄生大師絛蟲。 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/f2897ccbec1e Powered by Firstory Hosting
