Although the Venn diagram is not attached, I was able to find it and the characteristics in A are:
Chlorophyll in chloroplasts
Autotrophic
Cell walls of cellulose
Large central vacuole
The characteristics under B are:
Heterotrophic
Cell walls made of chitin
Sometimes multinucleate
Hyphae
The mutual characteristics are:
Organelles
Cytoplasm
DNA in nucleus
Cell membrane
Therefore, A represents plants and B represents fungi.
