This had similar mercury levels to the phloem.

树皮的汞含量与韧皮相近。

The companion cells are the little guys scattered throughout the larger phloem cells.

伴生细胞是分散在较大韧皮细胞的小细胞。

The two more distant trees had 2.9 and 2.0 respectively.

另外两棵较远的树的韧皮千克汞含量分别为2.9及2.0。

Phloem from the tree at the eruption site had 9.5 micrograms of the metal per kilogram.

位于喷发点的树上的韧皮千克含有9.5毫克汞。

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，延伸维管束，木质负责水，韧皮负责在光合作用后。

Carbon travels through the phloem into the branches, down the tree trunk and even all the way down to the soil.

碳通过韧皮传到树枝，沿着树干甚至一路传到土壤。

And there are two main types of cells that make up that vascular tissue: xylem and phloem.

构成维管组织的细胞主要有两种：木质和韧皮。

Phloem cells, on the other hand, transport stuff mostly in the opposite direction as xylem cells.

另一方面，韧皮细胞与木质细胞的方向相反。

Right beside the phloem is the tree’s other tissue type: the xylem.

韧皮旁边是树的另一种组织类型：木质。

And if we zoom in, we'll notice its xylem and phloem cells snuggled together, just like they were in the stem.

如果我们放大，我们会注意到它的木质和韧皮细胞依偎在一起，就像它们在茎一样。

Mercury is carried there by the phloem and selectively deposited in it, rather than in the plants' more permanent parts.

汞通过韧皮被转到树皮，有选择性地在其沉积，而非在自己不易更新的位沉积。

Carbon and water, more than 1,000 liters of water, in fact, flow freely through the phloem and xylem tubes carry it along.

碳和水，实际上超过 1000 升的水，自由流动于韧皮和木质的管道。

A second set of channels, the phloem, found just under a tree's bark, carries the products of photosynthesis to the roots.

第二组通道叫韧皮，就长在树皮之下，它将光合作用的产物送到树的根。

Xylem and phloem are bundled together to form the veins of a plant — the subway map that connects the leaves, stem, and roots.

木质和韧皮捆绑在一起形成植物的脉络——连接叶子、茎和根的地铁地图。

The pith is encircled by a ring of xylem, and xylem is encircled by a ring of phloem… phloem, and pith growth is usually pale in color.

髓被一圈木质包围，木质又被一圈韧皮… … 韧皮包围，髓生长通常呈浅色。

So the xylem cells are transporting nutrients from the roots to the leaf, and the phloem are taking the freshly made sugar from the leaf to the rest of the plant.

所以木质细胞将营养物质从根送到叶，韧皮将新鲜的从叶送到植物的其他分。

The xylem cells, which are moving water and nutrients up through the stem, are clumped toward the inside of the bundle, and the phloem, which is transporting sugars down through the plant, is clustered toward the outside.

木质细胞负责将水分和营养物质通过茎向上送，它们向束的内聚集，韧皮负责将分向下送，它们向束的外聚集。

The ability to perceive the world through the eyes and ears of other beings, through the phloem and xylem of trees, even reconnects us, humans, to the fantasticand richly diverse network of organisms that make up our shared Earth.

通过其他生物的眼睛和耳朵、树木的韧皮和木质来感知世界的能力，甚至将我们人类与构成我们共同地球的奇妙而丰富多样的生物体网络重新连接起来。
