Seeds offer several advantages to angiosperms. Seed formation is more dependable because:

1. Seeds have better adaptive strategies for dispersal

2. Reproductive processes become independent of water

3. Hard seed coat provides protection to the young embryos

4. They generate new genetic combinations leading to variations
