At first, it may seem that the fungus receives the greatest benefit from a mycorrhizal association. After all, a plant can produce organic compounds that the fungus can use. However, the fungus is also useful to the plant. For one thing, the fungal hyphae increase the absorptive surface of the plant roots. Table 20-2 records the inflow of phosphate in two kinds of onion plants—mycorrhizal and non-mycorrhizal plants.

anonymous · Answer

Determine/explain which type of onion plant took up the most overall phosphate. Then, explain how the length of the trials affected the total amount of phosphate absorbed by each of the two types of onions.
