Yep as you guys point out, some plants have digestive systems. Interesting topic.

I wonder if being a heterotroph is considered more evolutionarily advanced than being an autograph. I guess it depends on which form of nutrient acquisition is more efficient in a particular circumstance.

Many heterotrophic plants actually do not have digestive systems, they obtain nutrients from their host/partners parasitically (e.g. mistletoe or dodder) or symbiotically (e.g. lichen or mycorrhiza). Carnivorous plants are usually an adaptation to nitrogen limited soils.
