Refer to the figure showing two different plant symbioses. In both A and B, the fungal and bacterial cells remain surrounded by plant plasma membrane instead of directly entering the plant cells.What advantage does this separation provide for the plant?

Quizplus · Accepted Answer

By surrounding the fungal and bacterial cells with plasma membrane, the plant can control what nutrients enter its cells from the symbiotic partners. This allows the plant to selectively uptake only the nutrients it needs, preventing over-uptake of potentially harmful substances. Additionally, this separation helps prevent the symbionts from becoming pathogenic and colonizing the same cells.
