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气，细菌入侵就更畅通无阻了。

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

再者，赖希认为，气对于植缓慢适应风力也极为重要。

Plants get their oxygen from the air through the stomata.

植通过气从空气中获取氧气。

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

但它们也可以关闭气，以防止水等其他东西逸出。

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小嘴气。

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

果植有所移动，那么无论是因为风还是其他什么原因而发生移动，都会影响气响应方式。

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

每隔几个细胞，你看到被称为气大开口正嘴巴般吸入空气，并吐出氧气。

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空间是气，两边是保卫细胞。

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

即叶子表皮上小，称为气，可以让二氧化碳气体进入，这是光合作用关键部分。

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气小，气打开后，二氧化碳可以扩散到叶子里。

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过程为植提供食, 并通过称为气隙吸入空气。

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，再通过细小气口排出植株。

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，气——允许促成光合作用气体交换小——在夜晚开启前紧紧地保持关闭。

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小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，当植没有足够水喝时，叶子上被称为气小开口就会开始关闭以保存水分。

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《空气清洁法案》通过后10年，红杉叶开始重新打开。

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，因此进出唯一途径是通过气，气由保卫细胞调节。

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

我们会在叶子背面找到那些时髦小气。

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.

关于它们压力状态信号可以传递给任何接触根部邻近植，所以这些植也知道通过关闭气来为干旱做准备。

Since water escapes the plant through the stomata, it's best for the plant to have them on the side of the leaf that does not get blasted by the sun all day.

由于水分通过气从植中逸出，所以最好将气长在叶子一侧，以免整天被太阳晒伤。
