为什么植物可以净化空气？
1、植物通过光合作用吸收二氧化碳，释放氧气，从而增加空气中的氧气含量，减少二氧化碳。
2、植物的叶片表面能吸附空气中的微小颗粒物和污染物，如灰尘和有害气体，起到过滤作用。
3、植物根系能够吸收土壤中的有害物质，如重金属和农药残留，减少这些物质进入空气。
4、植物释放的挥发性有机化合物（VOCs）可以吸附空气中的有害气体，如甲醛和苯，起到净化作用。
5、植物通过蒸腾作用释放水蒸气，可以增加空气湿度，减少空气中的细菌和病毒，改善空气质量。
总之，植物通过多种方式净化空气，包括吸收有害气体、过滤颗粒物、吸收土壤污染物、释放有益物质和增加空气湿度，对改善环境质量具有重要意义。
