    Do you know anything about alternating generations or how ferns reproduce (sexually and asexually)?

    The gametophyte produces gametes, and the sporophyte produces spores. You need to figure out whether the generation in that picture produces spores or gametes.

    So... if it produces spores, what generation is it?

    Right. In the case of ferns, conifers, flowering plants, and several other groups, the big leafy plant that you see is always going to be the sporophyte. Ferns have a free-living gametophyte too, but it's small and not so easy to spot. Mosses are a bit different. In their case, the leafy plant that you see is actually the gametophyte, whereas the sporophyte is the little capsule on a long stalk (which is also part of the sporophyte) that you sometimes see sticking out of the top of a leafy moss plant.
