There are three types of chloroplast-containing cells: palisade mesophyll cells, spongy mesophyll cells, guard cells.

Guard cells can sense kinds of environmental stimulus and adjust the stomatal pore to regulate gas and water exchange in and out of plants.

保卫细胞能感知多种环境刺激，通过改变气孔孔径来调节气体和水分进出植物。

In addition, ABA microinjected into guard cells markedly induced H2O2 production, which preceded stomatal closure.

另外，内源ABA（通过显微注射）也可诱导保卫细胞产生H2O2，进而促进气孔关闭，这些效应同样可通过显微注射CAT或DPI被部分逆转。

Four hours after stress relief, the ABA contents of leaves and guard cells were near the prestress value.

失水处理后保持湿润恢复膨压的叶片和其保卫细胞的脱落酸含量没有增加。

When stomatal closure, K+ content decreased and Ca 2+ content increased obviously in guard cells.

伴随着气孔关闭，保卫细胞中最明显的变化就是K+、Cl-含量的下降和Ca2+含量的上升。
