Question

It has been hypothesized that fungi and plants have a mutualistic relationship because plants make sugars available for the fungi's use. What is the best evidence in support of this hypothesis? A. Fungi survive better when they are associated with plants.
B. Radioactively labeled sugars produced by plants eventually show up in the fungi with which they are associated. C. Fungi associated with plants have the ability to undergo photosynthesis and produce their own sugars, while those not associated with plants do not produce their own sugars. D. Radioactive labeling experiments show that plants pass crucial raw materials to the fungus for manufacturing sugars.

Answer 1

Option (B) Radioactively labeled sugars produced by plants eventually show up in the fungi with which they are associated is correct.

The best evidence in support of this hypothesis is that radioactively labeled sugars produced by plants eventually show up in the fungi with which they are associated.

How Fungi and plants are related?

• The first is that they are both eukaryotic, which means that their cells have a nucleus and membrane-bound organelles, and that they both belong to the Eukarya domain.
• They are both immobile, have cell walls, and are frequently multicellular, meaning they are made up of several cells.

• Mycorrhizae are plant and fungal symbiotic relationships.
• As fungi infiltrate a host plant's root system, the plant's capacity to absorb water and nutrients increases, and the fungus has access to the plant's photosynthesis-produced carbohydrates.

• According to computational phylogenetics, fungus and other eukaryotes are more closely related to one another than plants are to us.
• The clade of mammals and fungi known as opisthokonta is named for a solitary, posterior flagellum that existed in their most recent common ancestor.
