So woody tissues seems to have first appeared as  an adaptation for keeping plants hydrated.

因此，木质组织最初似乎是作为一种让植物保持水分的适应性组织出现的。

Woody tissue, like the kind found in tree trunks, give the Saguaro its height, but the Saguaro survives with way less water than most trees.

木质组织，就像在树干里见到的一样，成就了树形仙人掌的身高，但它们依靠着比大多树少得多的水生存着。

And at the same time as plants  were developing woody tissues, they were also making a few more modifications.

在植物发育木质组织的同时，它们也在进行更多的修饰。

And unlike those plants found at Gilboa  that were originally mistaken for " trees, " even though they didn't have true woody  tissue, Archaeopteris was full of the stuff.

与在 Gilboa 发现的那些最初被误认为是“树” 的植物不同，即使它们没有真正的木质组织，Archaeopteris 也充满了这种东西。
