Which characteristic best indicates that the organism in question is a fungus, not a plant?

a)
cell walls

b)
eukaryotic

c)
heterotrophic

d)
usually multicellular

The correct answer is-

C)  heterotrophic

Plants and fungi both are eukaryotic organisms ( having true nucleus and membrane bound sub-cellular organelles) but both form different kingdoms.

Plants can synthesize their own food through photosynthesis ( formation of food using carbon dioxide and water in the presence of sunlight). They are therefore called autotrophs.

On the contrary, fungi can not syntheisize their own food and called heterotrophs as they depend on external sources ( such as living organisms or dead and decayed organic matter).

Thus, option D) indicates that the organism in question is a fungus, not a plant.
