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，韧皮部负责在光合作用后运输。

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

看维管束是如何在叶子中展形成叶脉的，这样它就能把水传遍整个叶。

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

那么，我们可以用芦笋及其维管束来修复脊髓吗？

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，通过维管束进入叶子，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.

所以在这些发现发后不久，我正在家里做芦笋当晚餐， 切掉末端后，我注意到茎上充满了这些微通道维管束。
