[Avodah] The daf yomi in Chulin 128a Tanaim hold the the kishus planted in an otsits sh’aino nakuf is yonaik min ha'aretz - is their botany different than ours?

[hankman]

The daf yomi in Chulin 128a both the Tana Kama and R. Shimon hold the the kishus planted in an otsits sh’aino nakuf and whose branch is protruding over the edge is yonaik min ha’aretz derech ha’avir. Can anyone explain just what the plant is obtaining from the aretz that would cause the plant to still be considered mechubor la’aretz? The co2, o2 and water vapor are all obtained directly (just) from the atmosphere and not from aretz via the atmosphere. What am I missing here?
