No.

plants do not digest food, they make their own from sun-light, water, CO2, and soil minerals.

Plants don't need a digestive system. Animals, in other words, do.I think plants are the only organisms that don't have a digestive system.

Some unsegmented worms that have taken up a parasitic livelihood (such as Hook Worms and tape worms) have lost what digestive they once had and absorb their nutrients directly through their skin.
