But what is the mechanism that makes leaves "intake" (absorb, adsorb,
injest, osmosis, etc.) the poison.

Why would a leaf, which is an excretion organ of the plant for liquids
(transpiration) and gases (outgassing) ... why would that outgassing leaf
INTAKE the poison?

The water comes up the roots and out the leaves. Why would the leaves
intake the liquid poison?

They also take in, they breath so poison enters through the leaf and
affects the whole plant root and all.
