If we're talking about complex multicellularity (ontogeny resulting in 
multicellular differentiated organs), it's also found in crown 
heterokonts and fungi, and even in plants, the rhodophytes and 
streptophytes developed it separately, and there are chlorophytes that 
are arguably multicellular.

If I wanted a morphological synapomorphy, I'd go for gastrulation.
