1.Others have only one flagellum. The flagella rotate, pushing the bacteria through the water.

而有的细菌只有根鞭毛。鞭毛的旋转可以推动细菌在水中行进。

2.They can also have flagella which are long, whip-like protrusions that allow the bacteria to move.

细菌表面也有类似鞭子的突出物，称为鞭毛，它们参与协助细菌动。

3.Leptospira is also a motile bacteria because it has flagella that help it move around.

钩端螺旋体也能动菌，因为它有可以帮助动的鞭毛。

4.As in modern specimens, the fossil sperm lacked a flagellum, or tail.

与现代标本，石精子没有鞭毛或尾巴。机翻

5.The cells use rotating flagella to propel towards the surface of the rock, which they attach to with the help of sticky appendages.

细胞利用旋转的鞭毛游向石头的表面，然后利用富有粘性的附属物附着于石头上。

6.It has pili and a single polar flagellum, kind of like a tail, at one end which it uses for movement through the gastrointestinal tract.

它含有菌毛和条像尾巴的鞭毛；鞭毛可以移动，使其能在胃肠道中移动。

7.Over billions of years of evolution, nature has come up with lots of molecular machines, from whip-like flagella that help cells move, to enzymes that catalyze chemical reactions.

在几十亿年的进过程中，大自然产生了许多分子机器，从帮助细胞动的鞭状鞭毛体到催生学反应的酶。

8.Matrix producers pump out the extracellular goo, swimmers assemble flagella and are free to move about or migrate, and spore-formers produce dormant, tough endospores that survive starvation, temperature extremes, and harmful radiation.

基质制造者能够分泌细胞外粘性物质，鞭毛可以自由活动和迁移，芽孢菌生产休眠、坚硬的孢子内壁，孢子内壁能够在饥饿、极端温度、以及有害射线下生存。

9.And when blue light shines onto the eyespot of an algae cell, a channel opens, sending an electrical signal that makes little flagella flap and propels the algae towards sunlight.

当蓝光照射到藻类细胞的眼点上时， 个通道打开，发出电信号， 使小鞭毛拍打并推动藻类朝向阳光。机翻
