Answer:
Explanation:
To clear my friend's misconception about plants and fungi, I will use the method by which each specie obtains their food to explain. 
- Plants are autotrophs that takes up energy from the sun to manufacture their own food. 
- Fungi is mainly a heterotroph that feeds on food that is already manufactured. 
- This is why you have fungi on a piece of stale bread after several days but you can never find a plant growing in such a place.
