One toxin coronatine makes plants' stomata open up, allowing bacteria to enter more freely.

一旦毒素冠菌素打开了植株的孔，细菌入侵就更畅通无阻了。

Space around the lower epidermis and cuticle are the stomata, with guard cells on either side.

下层表皮和角质层周围的间是孔，两边是保卫细胞。

But they can also close the stomata to prevent other things like water from escaping.

但它们也可以关闭孔，以防止水等其他东西逸出。

Plants get their oxygen from the air through the stomata.

植通过孔从获取氧。

Reich notes that stomata also play a role in a plant's slow adaptation to wind.

再者，赖希认为，孔对于植缓慢适应风力也极为重要。

Even movement of the plant, whether from wind or something else, affects how reactive stomata are.

如植有所移动，那么无论是因为风还是其他什么原因而发生的移动，都会影响孔的响应方式。

And personally, I love that stomata look like creepy little mouths.

就我个人而言，我喜欢那些看起来像令人毛骨悚然的小嘴的孔。

Every few cells, there are huge openings called stomata, like mouths, sucking in air and blowing out oxygen.

每隔几个细胞，你看到被称为孔的巨大开口正如嘴巴般吸入，并吐出氧。

It's got these little pores called stomata, which open up so carbon dioxide can diffuse into the leaf.

叶子底部有些被称为孔的小孔，孔打开后，二氧化碳可以扩散到叶子里。

Tiny openings in the epidermis of leaves, called stomata, let in carbon dioxide gas, a key part of photosynthesis.

即叶子表皮上的小孔，称为孔，可以让二氧化碳体进入，这是光合作用的关键部分。

And we'll find those funky little stomata on the underside of the leaf.

我们会在叶子的背面找到那些时髦的小孔。

Leaves provide food for the plant through a process called photosynthesis and breathe in air through pores called stomata.

叶子通过称为光合作用的过程为植提供食, 并通过称为孔的孔隙吸入。

Meanwhile, the stomata — tiny holes that allow the exchange of gases that enable photosynthesis — remain firmly closed until night when they open.

与此同时，孔——允许促成光合作用的体交换的小孔——在夜晚开启前紧紧地保持关闭。

After water flows from the roots to the leaves through the xylem, it can exit the plant through the tiny stomata mouths.

水通过木质部从根流向叶后，再通过细小的孔口排出植株。

From the 1940s through the 1970s, the trees closed the tiny holes in their leaves known as stomata to protect themselves from acid rain.

从上世纪40年代到70年代，红杉树关闭了叶子上的小孔来保护自己免受酸雨侵袭。

When a plant isn't getting enough to drink, for example, tiny openings on its leaves called stomata start to close up to conserve water.

例如，当植没有足够的水喝时，叶子上被称为孔的小开口就会开始关闭以保存水分。

Signals about their stressed state can pass to any neighboring plants that touch roots, so those plants know to prepare for drought by closing their stomata, too.

关于它们的压力状态的信号可以传递给任何接触根部的邻近植，所以这些植也知道通过关闭孔来为干旱做准备。

The cuticle seals up the leaf, so that the only way in and out is through the stomata, which are regulated by the guard cells.

角质层将叶片密封起来，因此进出的唯一途径是通过孔，孔由保卫细胞调节。

Then, in 1982 or so, about 10 years after passage of the Clean Air Act that cut back on such pollution, the stomata began to reopen.

之后，在1982年左右即削减这类污染的《清洁法案》通过后10年，红杉叶孔开始重新打开。

Stop me if you've heard this before but plants need water, sunlight,   and carbon dioxide to photosynthesize, and they absorb that carbon dioxide  through pores called stomata.

如你以前听过这个，请打断我，但植需要水、阳光和二氧化碳来进行光合作用，它们通过孔吸收二氧化碳。
