Which of these is a feature not present in seedless plants that have contributed to the success of seed plants on land? a. Seeds have four layers of protective tissue, the seed coat, that improve survival by providing more protection from environmental stresses. b. The reduced gametophytes of seed plants are nurtured by sporophytes and protected from stress, such as drought conditions and UV radiation. c. Seed germination is solely mediated by water during episodes of heavy rain. Od. Pollen grains, with walls containing sporopollenin, deter herbivores.
