Question:
I have read that wetland plants have a special adaptation - tubes that carry oxygen from the air down to the roots. Where are these tubes located? How does this compare to the manner in which upland (traditional) plants transport oxygen? How do floating wetland plants like duckweed and lilies get oxygen?
