Question

Which of the following can be an evidence for the mutualistic relationship between mycorrhizal fungi and their plant partners? Fungi associated with plants have the ability to undergo photosynthesis and produce their own sugars, whereas those not associated with plants do not produce their own sugars. Radioactive labeling experiments show that plants pass crucial raw materials to the fungus for manufacturing sugars. Fungi survive better when they are associated with plants. Radioactively labeled sugars produced by plants eventually show up in the fungi with which they are associated.
