1 . Photosynthesis is often limited by the rate of CO2 diffusion from the atmosphere to the chloroplast.
CO2从大气中向叶绿体中的扩散经常限制光合作用的速率。

2 . In one single cell, sensitivity of mitochondria and cell nucleus to the external environment was not so good as that of the chloroplast.
在同一个细胞中，线粒体和细胞核对外界环境条件反应的敏感性不及叶绿体。

3 . There was an increased in the number and diameter of osmiophilic granules per chloroplast.
嗜锇颗粒的大小和数目也随着衰老而增加。

4 . The number of chloroplast and chlorophyll content in the dodecaploid are more than hexaploid, stomatal density are lower than hexaploid.
同时，十二倍体较六倍体的叶绿体数目明显增多，叶绿素含量提高，但气孔密度减小。

5 . Different solvents were used to distill chloroplast pigment, and then the extractive was separated with paper chromatography.
利用不同溶剂提取叶绿体色素，再用纸层析法对叶绿体色素进行分离，并对分离效果进行比较。
