coniferophyta aka conifers are a particular type of cone bearing seed trees. The biggest difference between them and anthophyta or angiosperms (flowering plants and tress) is the endosperm which is not found in conifers. This endosperm is the body of the embryo and what we normally think of as the 'fruit'. It is there to provide nutrients to the developing embryo.

The endosperm surrounds the embryo (it is not part of it). In addition to the endosperm and double fertilization, only angiosperms generate fruit (the seeds of gynosperms are naked); angiosperm megagametophytes lack archegonia (gymnosperm megagametophytes have two); the embryo of gymnosperms is nourished by a haploid tissue derived from the megagametophyte (unlike the 3n endosperm of angiosperms). Gynosperm sperm also swim a short distance (across the pollination droplet) before fertilizing the egg.
