Gas nutrients uptake by the leaves 陆生植物可以通过气孔吸收气态养分,如CO2 O2以及SO2等。 Leaves and other aerial plant organs are well able to take up nutrients in gaseous form such as CO2,O2, and SO, via the stomata

Uptake of mineral nutrients by the leaves 陆生植物因叶表皮细胞的外壁上覆盖有蜡质及 角质层,对矿质元素的吸收有明显障碍 The process of nutrients uptake by leaf cells is the same as that of nutrient absorption by plant root ce The uptake of nutrients in ionic forms from solution is limited as the outer epidermal cells of the leaf are covered by the cuticle(k)which occurs in all terrestrial(陆生) plant species. The cuticle consist of two components cutin(角质) and wax (腊质)
