Orchid seeds are tiny, with virtually no endosperm and with miniscule cotyledons. If such seeds are deposited in a dark, moist environment, then which of the following represents the most likely means by which fungi might assist in seed germination, given what the seeds lack?

A) by transferring some chloroplasts to the embryo in each seed

B) by providing the seeds with water and minerals

C) by providing the embryos with some of the organic nutrients the fungi have absorbed

D) by strengthening the seed coat that surrounds each seed

Explanation / Answer

Answer: C) by providing the embryos with some of the organic nutrients the fungi have absorbed
