Similarities
1. Both are seed-producing (spermatophyte) vascular plants with a dominant sporophyte generation.
2. Both produce pollen (male gametophytes) and ovules (female structures) and use seeds for dispersal and next-generation growth.

Differences
1. Reproductive structures: angiosperms produce flowers and their seeds are enclosed in ovaries that develop into fruits; gymnosperms have "naked" seeds (often on cones) and no flowers or fruits.
2. Fertilization and seed nutrition: angiosperms undergo double fertilization, producing a triploid endosperm that nourishes the embryo; gymnosperms lack double fertilization and the embryo is nourished by persistent female gametophyte tissue.
