Ling was doing the below exercise and she got confused whether bamboo has woody stem or soft stem. (竹子是属于草质茎还是木质茎?) Actually I am very confused too.

After googling and the below explanation makes the most sense for me :

草木之别的关键要看是否有“年轮”。木本植物每过一年,茎干的横断面便增添一圈同心轮纹,然而锯断竹子看,里面却空空如也。由此可知,竹子是“草”。而非“树”。竹子属禾本科多年生常绿植物,与稻、稗等同属一科

The difference between ‘woody stem’ and ‘soft stem’ is  the existence of ‘tree ring’.  By looking at the cross-section of a ‘woody stem’ plant, you can see the annual rings formed due to the growth of the stem(trunk). When you saw a bamboo stem, it’s empty inside. Therefore, bamboo is ‘grass’ and not ‘tree’. Bamboo belongs to the same group as paddy and millet.
