Orchid seeds lack substantial stored nutrients, which are essential for germination and initial growth. Fungi can form symbiotic relationships with orchid seeds, where the fungi provide organic nutrients to the seeds. This mutualistic interaction is crucial for the germination of many orchid species, as the fungi supply the necessary carbon and energy sources to the seedlings.
