【問題】植物有無細胞自殺機制

[neptune36221 10]

在查閱campbell時,

知道動物有溶體裡頭含有酵素可行細胞自殺

促使舊細胞死亡

但植物沒有溶體,其細胞大多木質化累積成為木材

但在觀察植物細胞時,大多謹可發現細胞璧.

胞器大多消失,令我困惑不已

希望諸位高手能解答,越詳細越好.Thanks

Campbell翻到植物激素那章，講乙烯的地方有提到植物細胞自殺。

apoptosis is a crucial mechanism for all multiple cell organisms...

a very common way is the disturbance of balance between Bax and Bcl which eventually leads to the expose of cytochrome C into cytoplasm and activate the caspase complex. Such pathway should exist in plants as well.
