Biology
Applying fungicides to plants may result in the plants showing signs of phosphorus deficiency. What is the most likely explanation for this observation? The fungicide destroys phosphorus transporters in the plasma membrane of root cells. The fungicide blocks ATP synthesis, so phosphorus cannot be absorbed into plant cells. The fungicide destroys mycorrhizal symbionts. The fungicide inhibits nitrogen fixation. After fungicide is sprayed, plant cell walls impede the uptake of phosphorus to limit the amount of fungicide that enters the plant.

The fungicide destroys mycorrhizal symbionts.
Explanation:
Mycorrhizal symbionts is the symbiotic association that is present between plants and fungi. Plants provide food materials in the form of sugar to the fungi while fungi fixes phosphorus for the plant that is present in the soil in unavailable form. When fungicide is sprayed, it kills the fungi present in the soil and deficiency of phosphorus occurs in plants.
