I want to know the answer to the following question:
What happens if a plant looses roots or its shoots?
All the background I'm provided with is that "In fact it is possible to grow an entire plant from a single leaf, as is the case with Saintpaulia, or even a single cell – which can dedifferentiate into a callus (a mass of unspecialised cells) that can grow into a new plant.". Is that enough to answer the question?
Answer: no
