Bamboo
noun
The kanji and the word are exactly the same. That means they share meanings as well!
Since this word is made up of a single kanji, it should use the kun'yomi reading which is also the reading you associated with the kanji, earlier.
このおはしは竹でできています。
These chopsticks are made of bamboo.
竹は、一メートルぐらいのたかさまで切ってしまうと、ねまでかれてしまいます。
If you cut a bamboo to about a meter high, it dies and even its roots wither.

I love working with bamboo! I made my television out of bamboo. It doesn’t work, but it sure looks nice.
