Concept:Fungi are set apart from plants mainly because they lack chlorophyll and cannot photosynthesise.
Explanation:Fungi are eukaryotes with nuclei, but unlike plants, they do not contain chlorophyll.
Without chlorophyll, they cannot make their own food and must absorb nutrients from dead or living organic matter.
Spores, fruiting bodies, and asexual/sexual reproduction also occur in other organisms, so they are not the main distinguishing feature.
Therefore, the key reason fungi form a distinct group of eukaryotes is the absence of chlorophyll.
Answer:B. no chlorophyll
