Can trees pull water up to the top in >1g situations? At >1g, the deep ocean pressure would be that much more.

Quick googling tells me that trees move water internally by capillarity, and suction caused by leave evaporation, both processes passive.

This puts limits on how high the column of water can be raised, yet at 1g we can have monstrous trees like sequoias, so maybe many kinds of trees would die, but the survivors would just grow shorter.

Abisal creatures, who knows how much pressure they can adapt to? They have populated our oceans as deep as they can go, the planet has nothing stronger to challenge them.

		you're focusing on sea dwelling creatures. what about land based? would animals get as large? would more calories need to be consumed for the extra effort necessary to move around in what ever >1g is around? some of these are are between 1.9x and 10x the size of earth. working twice as hard every day for everything be one thing, but 10x the effort? what would be the atmospheric pressure at >1g? what effect would that play as well? not only would you be heavier, but you'd have to work harder to breathe. again, lots of questions about the these differences that make it a lot more complicated than the right amino acids floating around in space.
