硅藻土是由蜂窝状的细胞壁形成的。
归有五个界：动物界、植物界、真菌界、茸鞭生物界——包括单细胞植物，如硅藻——和原生动物界，或单细胞生物体。
There are five kingdoms: animals, plants, fungi, chromists—including one-celled plants such as diatoms—and protozoa, or one-celled organisms.
再想想，这种单细胞的硅藻(网状硅藻属的硅藻)，是一种类型的海藻，放大了40倍后，显示了像“彩虹”那样的错综复杂五彩缤纷排列。
Think again. This unicellular diatom (diatom Arachnoidiscus), a type of algae, reveals an intricate rainbow pattern under 40x magnification.
相比之下，水母的碳含量为体重的10%，而硅藻(是单细胞海藻，属常见的浮游生物)则为20%。
Jellyfish, by comparison, are 10% carbon, and diatoms (single-celled algae that are common in plankton) 20%.
硅藻已经通过胞外分泌二氧化硅，这是细胞直接把物质分泌出细胞壁的一个生物过程。
Diatoms already secrete silica by exocytosis-a biological process by which cells direct secreted material outside the cell walls.
它的五颜六色效果是由于硅藻的像玻璃外壳包围着机体的二氧化硅细胞壁。
The colorful effect is due to the diatom's silica cell wall, which encases the organism like a glassy shell.
上图就是旧金山海湾的一个浮游生物网内聚集的单细胞植物硅藻——这种藻类在世界各大海洋都广泛分布。
The single-celled diatoms below—the likes of which are found in oceans worldwide—were collected with a plankton net in San Francisco Bay.
硅藻土(下文简称DE)是一种被称为硅藻的石化单细胞海藻。
Diatomaceous earth (which we shall hereby call DE because it's a lot easier to type) is the fossilized remains of single-celled algae called diatoms.
硅藻类的营养细胞是二倍体，它是由配子融合直接产生的。
In diatoms the vegetative cells are diploid, and are formed directly by the fusion of gametes.
在二维和三维的几何结构有大量的自然世界，从复杂的晶体形状海星，硅藻的单细胞有机体，像。
Geometric structures in two and three dimensions abound in the natural world, from complex crystal shapes to starfish, and unicellular organisms like diatoms.
硅藻一种由两个互联对称瓣构成硅细胞壁的、硅藻纲类的微小单细胞或群体的细胞藻。
Any of various microscopicone-celled or colonial algae of the class bacillariophyceae having cell walls of silica consisting of two interlocking symmetrical valves.
结果表明，光暗周期对硅藻胞外多糖生产的影响具有种间特异性，且与细胞生长周期有关。
The results showed that the influences of light-dark cycle on production of extracellular polysaccharide were species specific, and dependent on the growth phase.
一些藻类的细胞壁的化学成分有所不同，例如硅藻属的细胞壁含有硅化物，石灰质藻类的细胞壁含有钙。
The walls of some algae differ, e. g. the silica boxes enclosing diatoms, and the calcareous layer on the cell walls of calcareous algae.
瓣硅藻的两片硅化的细胞壁之一。
One of the two silicified halves of the cell wall of a diatom.
长链似乎降低了细胞的下沉速率，有助于硅藻生活在理化条件都比较适合生长的水体上层。
Longer chains affect sinking rates and thus likely help the diatom remain suspended in the upper part of the water column where physical and chemical parameters are more favorable for growth.
长链似乎降低了细胞的下沉速率，有助于硅藻生活在理化条件都比较适合生长的水体上层。
Longer chains affect sinking rates and thus likely help the diatom remain suspended in the upper part of the water column where physical and chemical parameters are more favorable for growth.
