The correct answer is:
If both assertion and reason are true and reason is the correct explanation of assertion.
The fungi of endomycorrhiza invade the cells of the root cortex, with a portion lying externally as a loose mass of hyphae in the soil. Mycorrhiza cause considerable stimulation of growth in nutrient deficient soil. The greatest stimulation occurs in the uptake of phosphates. Mycorrhiza can take up phosphate at that low concentrations at which they are unavailable to nonmycorrhizal roots.
