盐地生长的植物，叶肉细胞中会出现一种特殊的管泡状结构，这种结构由许多管状和泡状物质组成，它的外面还有一层包膜。它可能由叶绿体外膜变化而来，并且在盐渍条件下逐渐发育增大，结构日趋复杂。这种结构可能是一种溶酶体，在细胞质中能促进细胞内物质的水解，同时在液泡中被其他酶所消化，故能提高液泡中溶质的浓度，减少水分外渗，对于防止细胞过度失水有一定作用。因此，这种结构可能对于植物的抗盐有重要意义，是一种适应性反应。
In salt-grown plants, a special tube-like structure emerges in the mesophyll cells. This structure consists of many tubular and bubble-like substances with a coating on the outside. It may be chloroplast from the outer membrane changes, and gradually grow under salt conditions, the structure is increasingly complex. This structure may be a lysosome in the cytoplasm can promote the hydrolysis of intracellular substances, while in the vacuole by other enzymes to digest, it can increase the concentration of vacuoles in the solute to reduce the water extravasation, to prevent over-cell Water loss has a role. Therefore, this structure may be of great significance for the salt resistance of plants, is an adaptive response.
