The characteristic of fungi that resulted in them being placed in a separate kingdom is Fungi lack chlorophyll.
What do you mean by Kingdom?
Kingdom may be defined as a taxonomic classification of the second-highest level, just below the domain.
Fungi possess only a single nucleus and spend their much life. Some fungi are immobile in nature due to the presence of ergosterol which stabilizes the fungi in a definite space.
Unlike the Plantae kingdom, the kingdom of fungi lacks the chloroplast as well as cholorophyll. Hence, they do not perform photosynthesis.
Therefore, the characteristic of fungi that resulted in them being placed in a separate kingdom is Fungi lack chlorophyll.
