[問題] 維管束的發育
我想請問
(1)植物維管束的發育過程包括從種子發芽到成為完整植株
以及
(2)根和莖的交接 維管束是有怎麼樣的變化(根的維管束外側木質部;內側韌皮部/莖
的維管束內側木質部;外側韌皮部-這兩者之間怎麼接起來)
可能是我查詢的方式不對 我查不太到資訊
最多就只能查到「原形成層先向內分化出原生木質部,再向外分化出原生韌皮部,最後再
生成後生木質部及後生韌皮部......」這樣的資訊
能不能告訴我答案或者是要怎麼樣搜尋才能得到我想要的答案

好像有懂一點點
其實困惑的說看一篇文章說(作者應該是我們學校教授):
初生形成層向內分化出初生木質部後向外分化出初生韌皮部吧啦吧啦的 但很懷疑那根怎
麼辦

我說的那一篇網址
你給的連結我也看過但...有看沒有懂
有看過根部切片了(實驗課有玻片
但問題是在於「如何how」 不是觀察到的現象

好像可以理解 但為什麼會扭轉 為什麼「要」扭轉 是什麼機制讓維管束扭轉的?

意思是每一個維管束都像緞帶一樣 然後各自扭轉嗎?
那扭轉的地方......切面長怎樣啊? 像骨牌一樣只是一個木質部一個韌皮部 是類似這樣的
感覺嗎?
