植物细胞的液泡中的液体称为细胞液(cellsap),其中溶有无机盐、氨基酸、糖类以及各种色素,特别是花青素(anthocyanin)等。细胞液是高渗的,所以植物细胞才能经常处于吸涨饱满的状态。细胞液中的花青素与植物颜色有关,花、果实和叶的紫色、深红色都是决定于花青素的。此外,液泡还是植物代谢废物屯集的场所,这些废物以晶体的状态沉积于液泡中。

It is generally assumed that the pools of ions that exchange very slowly with the external medium are localized in the cell SAP.
由于细胞液中存在着来源于细胞质的物质,液泡的自体吞噬活性曾受到怀疑。
