The ultrastructure and distribution of chloroplasts, mitochondria, peroxisomes, and other cellular constituents have been examined in cross sections of leaves from plants with either high or low photosynthetic capacity. Photosynthetic capacity of a given plant cannot be correlated with the presence or absence of grana in bundle sheath cell chloroplasts, the presence or absence of starch grains in bundle sheath or mesophyll cell chloroplasts, the chloroplast size in bundle sheath or mesophyll cells, or the location of chloroplasts within bundle sheath cells. We conclude that the number and concentration of chloroplasts, mitochondria, and peroxisomes in bundle sheath cells is the most reliable anatomical criterion presently available for determining the photosynthetic capacity of a given plant.
已经在高光合能力和低光合能力植物的叶片横切面上检查了叶绿体、线粒体、过氧化物酶体和其他细胞成分的超微结构和分布。 特定植物的光合能力不能与束鞘细胞叶绿体中嵴的存在或不存在、束鞘或叶肉细胞叶绿体中淀粉粒的存在或不存在、束鞘或叶肉细胞中叶绿体的大小或叶绿体在束鞘细胞内的位置相关联。 我们得出结论，束鞘细胞中叶绿体、线粒体和过氧化物酶体的数量和浓度是目前确定给定植物光合能力的最可靠的解剖学标准。
