植物的营养器官

AI overview

A leaf is a flattened plant part that grows from stems and varies widely in shape and structure across different plant species. Leaves matter because they are where plants capture sunlight and conduct photosynthesis, the process that produces the food and oxygen that sustains most life on Earth.

叶（leaf，foliage）是较高等植物的营养器官，侧边发育自植物的茎的叶原基。叶内含有叶绿体，是植物进行光合作用的主要場所。同时，植物的蒸散作用是通过叶的气孔实现的。有些植物的茎為了不讓水分被蒸散掉，而演變出如仙人掌般針狀的葉子。叶只出现在真正的茎上，即只有维管植物才有叶。蕨类、裸子植物和被子植物等有胚植物（较高等）都有叶。相对地，非維管植物或非植物则没有真正的叶，例如苔蘚植物、藻类、真菌和地衣；在这些中有与叶相似的结构，但只能作为类似物。但有学者认为，上述“叶是茎的外延”，只是狭义的；广义的叶，应该指所有能行光合作用的组织结构。
