In C4 plants there are two types of chloroplast.
在C4植物中有两种类型的叶绿体。
In fact, the distinction between C3 and C4 plants is not always clear-cut.
实际上，c3与c4植物并非总是有着明显的区别。
In hot, sunny climes, these C4 plants are half as efficient again as their C3 counterparts.
在炎热，阳光充足的气候下，C4植物的效率比跟它们相似的C3植物高出一半。
Other researchers, meanwhile, are trying to isolate the genes responsible for C4 plants' unusual anatomy and biochemistry.
与此同时其他研究人员正致力于分离决定C4植物异常结构和生化特性的基因。
Among C4 plants, however, special leaf anatomy and a unique biochemical pathway enable the plant to thrive in arid conditions.
然而，在C4植物中，特殊的叶片解剖结构和独特的生化途经使得C4植物可以在干旱的条件下茁壮成长。
Thus C4 plants lessen photorespiration by carrying out photosynthesis only in cells that are insulated from high levels of CO2.
因此C4植物减少光呼吸的光合作用仅在细胞免受高水平的二氧化碳。
The results showed that there are certain differences of sensibility in response to natural strong light or photooxidation between C3 and C4 plants.
结果表明C_3和C_4植物对自然强光或光氧化作用响应的敏感性存在一定的差别。
Some C4 plants, for example, absorb CO2 and photosynthesise it at either end of special elongated[4] cells, instead of separating the functions out into two different types of cell.
比如说，有的C4植物对CO2的吸收和光合都是分别在某一类长形的特殊细胞两端进行，而非分散到两类不同的细胞中。
But some plants, including maize and sorghum, have evolved to use a type called C4.
但是一些植物，包括玉米和高粱，进化成了使用C4型的光合作用。
In the following graph the effect of the atmospheric concentration of CO2 on the photosynthesis rate in plants C3 and C4 is observed. The arrows indicate the compensatory points of each plant.
在下图里，观察c3和C4植物之大气中的CO2浓度对光合作用速率的影响。箭头表示每棵植物的补偿点。
The condensed water from plants of C4 , styrene and ABS was recycled and applied to heat salt water in production of acrylonitrile-butadiene rubber, and then used for agglomerating and washing.
中国石油兰州石化公司合成橡胶厂将碳四、苯乙烯、丙烯腈-丁二烯-苯乙烯嵌段共聚物等装置的凝结水收集后，先用于丁腈硬胶聚合用盐水的加热，换热后的回水再用于凝聚和洗涤用水；
