  We present computer simulations of three systems of randomly branching
polymers in d=3 dimensions: ideal trees and self-avoiding trees with annealed
and quenched connectivities. In all cases, we performed a detailed analysis of
trees connectivities, spatial conformations and statistical properties of
linear paths on trees, and compare the results to the corresponding predictions
of Flory theory. We confirm that, overall, the theory predicts correctly that
trees with quenched ideal connectivity exhibit {\it less} overall swelling in
good solvent than corresponding trees with annealed connectivity even though
they are more strongly stretched on the path level. At the same time, we
emphasize the inadequacy of the Flory theory in predicting the behaviour of
other, and equally relevant, observables like contact probabilities between
tree nodes. We show, then, that contact probabilities can be aptly
characterized by introducing a novel critical exponent, $\theta_{path}$, which
accounts for how they decay as a function of the node-to-node path distance on
the tree.
