Selaginella and Salvinia are considered to represent a significant step towards the evolution of seed habit because:
| 1. | Embryo develops in female gametophyte which is retained on parent sporophyte. |
| 2. | Female gametophyte is free and gets dispersed like seeds. |
| 3. | Female gametophyte lacks archegonia. |
| 4. | Megaspores possess endosperm and embryo surrounded by a seed coat. |
