These are different from the flowering plants in that while they still produce pollen, their sexual organs are cones rather than flowers, and their seeds, unlike the angiosperms, are not enclosed within an ovary. This avoidance of competition through diversity and specialism is known as resource partitioning. Many flowers make use of the wind to carry their pollen to the carpels of other flowers.
