Do you know the difference between lower plants and higher plants?

你知道低等植物和高等植物的区别吗？

The Arbuscular fungus had formed the symbiont with the ancient land lower plants before the appearance of the higher plant.

菌根真菌早在高等植物出现以前，就已经同古老的陆生低等植物形成了共生体。

Microalgae are a group of lower plants with the capacity of photosynthesis, widely distributed in marine, freshwater, soil and other environments.

微藻是一类能够进行光合作用的低等植物，广泛分布在海水、淡水、土壤等环境中。

Chitin fiber: chitin, also known as chitin, chitin, shell protein from crustacean shells and fungi, algae and other lower plants of the cell wall extract of a positively charged cellulose animals.

甲壳素纤维：甲壳素又称甲壳质、几丁质、壳蛋白，是从甲壳动物外壳及真菌、藻类等低等植物的细胞壁中提取的一种带正电荷的动物纤维素。

The protein content of shade-grown vegetation, for example, was much lower than that for plants grown in clearings.

例如，遮荫种植的植物中，蛋白质含量会远低于空地种植的植物。

Equally crucial is lower-tech research into basics such as crop rotation and mixed farming of animals and plants on small farms.

同样重要的是，开展对基础知识的低端技术研究，如庄稼轮作，在小型农场中发展动植物混养。

It follows that melon plants have a lower-than-usual rate of photosynthesis when their roots are in rain-soaked soil.

因此，当瓜类植物的根在雨水浸湿的土壤中时，它们的光合作用率低于通常水平。

The areas that are now desert were, like all arid regions, very susceptible to cycles of higher and lower levels of rainfall, resulting in major, sudden changes in distributions of plants and animals.

那片现在是沙漠的地区和所有干旱地区一样，对降雨量相对更大或更小的周期极为敏感，因此那里的动植物分布发生了巨大且迅速的变化。

Equipped with a pair of lower jaw buckteeth it used to dig for food, the RatCroc lived on plants and grubs.

鼠鳄拥有一幅较短的配有像山羊牙齿般的吻部，用于挖掘寻找食物，它依靠植物和蛴螬为生。

Many manufacturers in industries like carmaking prefer to build plants overseas, where costs are lower or markets are expanding.

许多制造商，比如汽车行业更的愿意在海外建厂，因为那里成本低廉，市场广阔。

He provided the dynamos, generators and power plants without which the bulbs were insubstantial baubles, and lit up lower Manhattan with them.

他提供了发电机、发生器和发电厂，没有这些，灯泡就是个没用的玩意。它们点亮了下曼哈顿。

Ideally, that demonstration facility would hit a cost of 5 cents or lower per kilowatt, giving coal-fired plants a run for their money.

设想中，该演示设备能让每千瓦电成本降到5美分活或者更低，这让燃煤发电厂的日子很不好过。

Warming is also reinforced when shrubs move northward and replace lower tundra plants.

气候变暖的另一铁证是灌木北移取代了苔原植物。

Strictly speaking, the decision applies only to emissions from vehicles, but another, similar case involving coal-fired power plants is pending in a lower court.

严格说来，该裁决仅适用于交通工具排放的气体，但是另一个类似的、涉及火力发电厂的案件正在低一级法庭等待宣判。

Because biodiesels can be made from materials derived from plants, which use carbon dioxide to grow, they potentially have a much lower carbon footprint than petroleum-based fuels.

由于生物柴油的原料都是来自与植物，而植物本身就会转化为二氧化碳，所以这样的话使用生物燃料的碳排放相对来讲比使用化石燃料的碳排放要小。

Lower nutrient levels in plants have implications for humans, as food derived from these crops can have reduced nutritional value.

植物中较低的养分水平对人类意味着负面作用，因为来自这样的作物的食品有降低了的营养水平。

The critical question is whether soils release more CO2 because faster-growing plants pump more in, or if soils release CO2 that would have stayed in the ground at lower temperatures.

关键的问题是，土壤释放出更多二氧化碳，是否因为植物生长更快，从而吸收了更多二氧化碳；是否因为土壤释放了应该在低温下保留在土壤里的二氧化碳。

关键的问题是，土壤释放出更多二氧化碳，是否因为植物生长更快，从而吸收了更多二氧化碳；是否因为土壤释放了应该在低温下保留在土壤里的二氧化碳。

Plants have at least two names - a genus name, which is general and capitalised, and a lower-case species name that is more specific, for example, the Jerusalem artichoke is Helianthus tuberosus.

植物至少有两个学名———一个属名，是总称，用大写，另一个是小写字母的种名，更加专属，比如，洋姜jerusalem artichoke就是向日葵属菊芋helianthus tuberosus。

Place them near your computer. Studies find that plants significantly lower workplace stress and enhance productivity.

将花花草草放在电脑边。研究发现，植物会大幅度降低工作压力并提高工作效率。
