Which of the following plants reproduce by spore formation?
Plants that reproduce using spores include Ferns (Option A), Mosses (Option B) and Liverworts (Option C). These are primitive plants. The trick is to remember that these plants do not have stems. Also, they have spots and fruiting bodies (liverwort picture) that produce spores. The cactus is a higher order plant. Remember that the cactus stem is swollen and is used for photosynthesis. Most plants do not produce spores and reproduce using seeds.
