Question

Quizplus · Accepted Answer

Since orchid seeds lack endosperm and have miniscule cotyledons, fungi can assist in seed germination by providing the embryos with some of the organic nutrients they have absorbed. The fungi can break down complex organic compounds present in the environment into simpler molecules that can be absorbed by the plant embryo. This way, the fungi act as a source of organic nutrients for germination and growth.
