Through that space stretches the vascular bundle, with xylem to transport water and phloem which transport sugars after photosynthesis.

通过这个空间，延伸出维管束，木质部负责运输水，韧皮部负责光合作用后运输糖。

Look at how the vascular bundle spreads out in the leaf to form veins so that it can spread water throughout.

看维管束是如何中展开形脉的，这能把水传遍整个片。

So, could we use the asparagus and its vascular bundles to repair a spinal cord?

那么，我们能否利用芦笋及其维管束来修复脊髓？

Water comes up through the roots and stem and enters the leaf through a vascular bundle, which contains a hollow tube for water transport called the Xylem.

水从根部和茎部上来，通过维管束进入，维管束包含一个空心管，用于运输水，称为木质部。

So not too long after these discoveries were taking place, I was at home cooking asparagus for dinner, and after cutting the ends off, I was noticing that the stalks were full of these microchanneled vascular bundles.

所以，这些发现公布不久后，我家做饭， 准备晚餐用的芦笋。 切掉两端后，我注意到茎里充满了这些带有微通道的维管束。
