txreformer 10 Posted October 14, 2009 Author Report Share Posted October 14, 2009 1應該是D吧2應該是BCDE吧厚角細胞 死細胞其它應該都可3我覺得是CE皮孔只有木本才有維管束形成層多年生才有木材只有木本才有請各位指教謝謝 Link to post Share on other sites
月殘追風 10 Posted October 15, 2009 Report Share Posted October 15, 2009 第三題...莖應該不會出現內皮吧.....而且莖木質化過後中間的細胞應該不能稱為"髓"吧....?(個人淺見....突然覺得自己好弱....) Link to post Share on other sites
