With bacterial cgc as main subject , the tests had been done to elucidate mechanism of self - organization for macroscopic rhythmic structure . the dynamics of cgc forming was observed by special techniques of waving culture and microscopic culture ; the differences in outer structure of cell wall and flagella number had been observed by atomic force microscope scanning ; integrity of cell wall was examined under tem ; outer membrane protein was analysed by sds - page and various substance and factors for cgc formation were determined 采用特殊的波動培養和顯微培養技術觀察潛生體形成動態;應用原子力顯微鏡掃描,比較細菌潛生體與繁殖體在細胞壁外層結構和鞭毛數量的差別;用透射電鏡觀察細胞壁完整性,以十二烷基硫酸鈉?聚丙烯酰胺凝膠電泳分析外膜蛋白的改變,并通過實驗分析多種物質和因素對潛生體形成的影響。

5 . the morphology of the two strains also shows that the flagella of ss - ori are around the cells , whilst the strain yz - ii6 has only a single flagellum grown at the polar of cells besides the different of cell size , though they both are bacillus and gram - negative 形態和生理生化特征也表明, ss - ori菌周生鞭毛,革蘭氏反應呈陰性, yz - 6菌為極生單根鞭毛,革蘭氏反應呈陰性。

From the view of bionics to imitate biology motion in the nature , this dissertation is devoted to study and design micro mobile robot in liquid by the help of propulsion mechanism of fish and flagella protozoa 本論文從模擬自然界生物運動仿生學的角度出發,主要借鑒魚類和鞭毛原生動物的推進機理,致力于研究與設計在液體中運動的微機器人。

Actin and myoglobulin are the compositions building muscles ' stretching function . microtubulin is the basic substance which provides the flagellum and cilium the function of movement 肌動蛋白及肌球蛋白乃是構成肌肉伸縮機構的組成部分,微管蛋白是賦予鞭毛及纖毛能動的基本物質。

An adult volvox consists of around 2 , 000 body cells , whose job is to move the organism around using their flagella , and 16 cells capable of reproducing 一個成年的團藻有大約2000個體細胞,它們的功能是控制自己的鞭毛來讓整個生物體運動起來,而另有16個細胞是有生殖能力的。

Using special stains , one can see that some bacteria have attached to them wavy - looking “ hairs ” called flagella . others have only one flagellum 用專用的污跡來觀察,你能見到一些細菌身上附著許多看似波浪狀的“頭發”稱之為鞭毛。另外一些(細菌)只有一個鞭毛。

Many bacteria lack flagella and cannot move about by their own power , while others can glide along over surfaces by some little - understood mechanism 好多細菌沒有鞭毛也沒法靠自己的力量運動,同時還有一些細菌可以通過一些尚不確知的機制在水面滑行。

An adult volvox consists of around 2 , 000 body cells , whose job is to move the organism around using their flagella , and 16 cells capable of reproducing 一株成年團藻由大約2000個體細胞組成,它們用它們的鞭毛移動整個團藻,而16個細胞具有繁殖功能。

Flagellum ( pl . flagella ) a whiplike extension of prokaryote cells , with a basal body at its base , whose beat causes locomotion of the cell 鞭毛:原核細胞的鞭狀延長部分,基部有基體,當鞭毛進行揮鞭式運動時可以促使細胞移動。

An axial filament , with a similar structure to a bacterial flagellum , is spirally wound about the protoplast inside the cell wall 在細胞壁內部,和細菌鞭毛有相同結構的軸向細絲包繞細胞質并使之螺旋化。

All the swarm cells have an obvious flagellum . myxamoebaand swarm cell can change between each other 所有的游動胞都具有一根明顯的長鞭毛,游動胞和黏變形體可互相轉化。

Bacteria under the microscope , even those with no flagella , often bounce about in the water 在顯微鏡下面的細菌,即便是那些沒有鞭毛的,也時常在水中亂跳。

Many protoctistans are motile , using pseudopodia , cilia or flagella 許多原生動物利用偽足、纖毛或鞭毛能運動。

The flagella rotate , pushing the bacteria through the water 鞭毛不斷旋轉從而推動細菌在水中前行。
