2026 選修生物II CH1-2 細胞的演化歷程
from 雷比特生物空中講 · host 雷比特老師
概述細胞演化的四次偉大飛躍，追溯生命從原始地球湯中誕生到形成複雜多細胞生物的壯闊史詩。首先描述生命從依賴環境有機物的異營生物轉變為能利用陽光自行生產食物的自營生物，即第一次飛躍。接著，第二次飛躍是應對光合作用產生的致命氧氣，生命從低效的無氧呼吸進化到高效的有氧呼吸，極大地增加了能量預算。第三次飛躍標誌著細胞結構從簡單的原核細胞升級為具備細胞核和內膜系統的真核細胞，這主要透過膜系統內陷和吞噬細菌形成粒線體和葉綠體的內共生假說完成。最後，第四次飛躍是從獨立的單細胞轉變為具備分工合作能力的多細胞生命，最終催生地球上所有複雜的生物形態。 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://g.co/gemini/share/9bdd23792de6 Powered by Firstory Hosting
