2026 biology talkshow:種子裡的糧倉博弈：子葉與胚乳 (選修生物II)
from 雷比特生物空中講 · host 雷比特老師
詳細介紹被子植物種子中胚乳與子葉之間的演化策略與營養競合關係。透過雙重受精的生物學背景，解釋三倍體胚乳作為能量倉庫與環境感應器的關鍵角色。對比兩大生存流派：單子葉植物如水稻保留胚乳作為行動便當，待萌發時再逐步吸收；而雙子葉植物如豆類則由子葉提前掏空並繼承胚乳養分。這種養分轉移透過精密的分子運輸機制達成，確保種子在不同環境下擁有最佳的生存競爭力。 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/9c423ed710cd Powered by Firstory Hosting
