It is a fern, they don't have seeds (nor flowers). They do have spores which are dust-like and grow under the leaflets looking like brown spots. Your plant looks quite okay in that photo. It's probably a Nephrolepis species, they're a fairly tough plant. They like good light, an organic well drained soil and to be kept moist. Although, for a fern they can take a bit of drying out. Misting the fronds occasionally will help if you're in a dry climate, or have the plant in dry air conditions. When repotting you can divide the plant into separate pots.
