运用实验方法区别共质体和跨细胞途径很难，对质外体和细胞到细胞途径综合作用的水分运输也缺乏有效的研究手段加以区分。
Symplast pathway and transcelluar pathway is difficultly distinguished by Experiment methods, and have no valid ways to make distinction between apoplast and cell to cell pathway.
钙离子在果实和叶片中的运输和分配不仅通过质外体途径也通过共质体途径。
There are both apoplastic and symplastic pathways of Ca2+ transport in fruit or leaf tissue too.
