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 :
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.
