organelle n.【生物學】細胞器。

organic

In much the same way that organs such as the heart and liver express specific functions in the organism as a whole , these sub - tissue structures carry out functions that permit the tissue to perform its task , however the organelles are much smaller 就象生命體中的心臟、肝臟之類器官各有其特殊功能一樣,這些次一級組織的功能使組織得以完成其任務,只是這些細胞器太小了。

Two hours after laying eggs , the secretions disappear , and the surfaces of cellular membranes break in a sort , but most of the organelle retain integrity and cellular inclusions appear in oviduct cavity 產卵后2小時,管腔內分泌物消失,細胞膜表面稍有破裂,但細胞器大部分保持完整。產卵后1天,管壁細胞解體較產卵后2小時明顯,管腔內出現細胞內含物。

Characters controlled by the dna of extranuclear organelles are not inherited according to mendelian laws and are transmitted only through the female line , since only the female gametes have an appreciable amount of cytoplasm 由于細胞質大多來自母體所產生的配子,所以由細胞核外的細胞器的dna所控制的遺傳性狀一般只隨母系而遺傳,也不符合孟德爾定律。

The phagosome is the organelle responsible for the destruction of infectious pathogens that cause such diseases as tuberculosis and salmonellosis , as well as pathogens that could be used in bioterrorism 吞噬小體是一種細胞器,其功能是消滅侵入人體的傳染性病原體,這些病原體能夠引起諸如結核病和沙門氏菌病等,故能夠被用作生物恐怖行動。

Ultrastructure . two types of epithelial cells are found in oviduct wall , one with clear cytoplasm and the other with dark cytoplasm . the clear cells contain abound organelle compared with the dark cells 明細胞較亮,胞質內細胞器種類和數量較多;暗細胞中細胞質密度較大,胞質內細胞器含量較明細胞少;明細胞可由暗細胞發育而成。

Our ultrastructural observations provided more convincing evidence that the hepatic phenotype was induced . before the sodium butyrate treatment , the cells contained few organelles except some mitochondria and ribosome 電鏡下觀察,胞漿中的細胞器較誘導前明顯增多,有線粒體、內質網和高爾基體以及大量的核糖體和糖原顆粒。

In animal and lower plant cells , cytoplasmic dynein involved in not only trafficking of subcellular organelles and target molecules , but also organizing and positioning of organelles such as golgi apparatus 細胞質力蛋白在動物和低等植物細胞中不僅參與細胞內細胞器和靶分子等的運輸,還參與高爾基體等細胞器的組裝和定位。

F - actin is so important a structure that it not only provides the tension for the cell , determines the cell ' s shape , but also supports the cell and arranges the space organization of organelles and some micromolecules 微絲是支撐細胞,決定細胞的形狀,賦予其強度以及對各細胞器及某些大分子進行空間組織安排的重要結構。

Cytoplasmic inheritance ( extrachromosomal inheritance ) the determination of certain characters by genetic material contained in plasmids or organelles other than the nucleus , e . g . mitochondria and chloroplasts 胞質遺傳:由質體或非細胞核的細胞器,例如線粒體或葉綠體所攜帶的遺傳物質決定遺傳性狀的遺傳現象叫做胞質遺傳。

The present paper reviews the construction and constitutes of pollen tube wall , the migration of generative cell and vegetative nucleus , as well as the movements of organelles and secretory vesicles in pollen tubes 本文就細胞壁的結構及組成,生殖細胞和營養核的移位,細胞器以及分泌小泡的運動等方面作了較全面論述。

The nucleus has two forms at the middle spermatid stage : fibrous one and condensed one . the nucleus extends into the radial arm . the number of organelles keeps increasing until secondary spermatocyte stage 與已有的報導不同的是,我們發現精原細胞分為兩類,其中i類精原細胞經過分化形成n類精原細胞。

Fixing agents ( fixatives ) should also render cell organelles and inclusions more visible and harden the tissue to prevent shrinkage and distortion during dehydration , embedding , and sectioning 固定劑(固定液)應能使細胞器官和內含物顯得更清晰,組織更硬,以防止在脫水、包埋和切片過程中收縮和變形。

Because of its slow growth rate and small volume , a special device was designed to observe the pollen tube growth and the dynamics of organelles more easily and accurately 由于擬南芥花粉管比較細小,生長速率較慢,本實驗采用了自行設計的一種觀察裝置,可以方便、精確地觀察擬南芥花粉管的生長行為。

Membranes of host mesophyll cells had marked pathological changes , organelles disintegrated , cytoplasm condensed , plasmalemma invaginated , and eventually the whole cell disintegrated and necrotized 寄主葉肉細胞的膜系統明顯病變,細胞器解體,細胞質凝聚,質膜內陷,最終整個細胞壞死解體。

Among them , mitochondria was damaged earliest , which suggested that mitochondria was a sensitive organelle to cadmium and could show damage decree led to by cadmium 其中,線粒體是最易受到損傷的細胞器,因此可作為鎘敏感指示細胞器。此外,在心肌細胞中的肌原纖維也受到鎘的損傷。

It is contained within the plasma membrane and comprises a colorless substance ( hyaloplasm ) containing organelles and various inclusions ( e . g . crystals and insoluble food reserves ) 在原生質膜內包含無色的基質(透明質) 、細胞器、還有各種的后含物(晶體,不溶性的儲存食物) 。

The different types of tumor cells were distinguishable by the size of the secretory granules , the electron density and the intracellular organelles which they contained 腫瘤細胞不同型的區別在于:細胞所含分泌顆粒的大小與其電子密度,以及他們所含的內在微細構造之差異。

The possible contamination of other organelle membranes was determined by using markers of enzyme inhibitors in different organelle membranes such as vanadate , azide , molybdate and nos “ 利用不同細胞器膜上atpase或其它酶的標志性抑制劑來檢測質膜純度。

A protein that mediates the transport of other proteins across the membrane of an organelle such as the endoplasmic reticulum , nucleus , mitochondria , and chloroplast 一種蛋白質,能作為其他蛋白質通過如內質網、細胞核、線粒體和葉綠體等細胞器官的膜的媒介。
