As far as I know, plants don’t have any kind of moving parts that help move water and nutrients from their roots to their crowns. So how do they do it? How do plants work against gravity?
It would make more sense to me if plants worked like fungi, spreading throughout the earth until they’re ready to reproduce, but no, upright plants are the whole organism. Is that not, like, super weird?
Plants are so weird. Like, “Hi, I’m a plant. I eat sunlight and communicate using mycorrhizal fungi. I have no muscles, but still break through concrete slabs. I have no heart, but still move water from my roots to my leaves.”

evaporation. they lose water from their leaves, creating negative pressure at the top to help pull water up.
it’s a bit more complicated than that, life is complicated and trees are weird, but that cycle of evaporation is the basic heat engine driving everything.
