| 1. | These shelflike inner folds are called cristae .
这些板状的内折叫做嵴。
|
| 2. | The mitochondria expanded and vacuolated and its cristae disappeared ; the double membrane was broken
细胞核形状不规则，核膜破损，异染色质聚集突出，核物质外流。
|
| 3. | A lot of vacuolus occurred in the cytoplasm of the cells . the nuclear membranes and cristae in mitochondria were disintegrated partially
中肠细胞内含有铅颗粒，细胞质出现空泡化，核膜和线粒体内嵴部分解体。
|
| 4. | Crista ( pl . cristae ) the structure formed by folding of the inner mitochondrial membrane , giving a large surface area for electron transport
嵴（嵴膜） ：线粒体内膜向内室褶叠形成的结构，可以为电子传递提供更大的表面积。
|
| 5. | Fig . 4 anoxia reperfusion group with the addition cerium ions : mitochondria swelling and cristae vague appear in the cell . cerium deposits can be seen in the mitochondria
图4缺氧再灌注加铈组：心肌细胞内线粒体肿胀，嵴模糊不清。线粒体内可见铈沉积颗粒。
|
| 6. | There were copper granules in the cells of midgut . a lot of vacuolus occurred in the cytoplasm of the cells . the cristae in mitochondria were disintegrated partially and copper granules were absorbed into mitochondria
中肠细胞内也分布有铜颗粒，细胞质出现空泡化；线粒体内嵴部分解体，并有铜颗粒附着在线粒体上。
|
| 7. | In spermatogenous cell , we could find dilated cytolemma , dilated nuclear membrane and fused crista of mitochondria . most of the sperm ' s cellular membrane dissolved and broke down into pieces . the central granule and mitochondrion showed little dissolving
久效磷可以使金鱼精子细胞质膜溶解，出现间断性断裂;有的精子头部变形，顶部出现凹陷;少量精子颈部中心粒复合体溶解;精子颈部线粒体有溶解现象，精子尾部的膜结构断裂。
|
| 8. | At low concentration of zn , the changes in ultrastructure were nuclei deformation , chloroplast swelling and disorder of thylakoid arrangement ; serious damages in ultrastructure caused by greater zn stress were indicated by scattered nucleoli , condensed chromatin , almost empty nuclei with nuclear membrane disrupted and nucleoplasm flowing into cytoplasm , swollen and partly dissolved cristae of mitochondria , disrupted and collapsed chloroplast envelopes , and some dissolved thylakoids that flew into cytoplasm
超微结构的变化也呈现加重趋势，低浓度处理的变化为细胞核变形、叶绿体膨胀、类囊体排列紊乱；严重的超微结构的损伤是核仁散开、染色质凝集，细胞核几乎成为空核和核膜破裂，核质散出；线粒体脊突膨胀和部分溶解；叶绿体膜断裂、消失和部分类囊体溶解和散到细胞质中。
