1. Presence of archegonia
2. Well developed vascular tissues
3. Independent gametophyte
4. Independent sporophyte

Which one of the following is common to multicellular fungi, filamentous algae and protonema of mosses?

1. Diplontic life cycle
2. Members of Kingdom Plantae
3. Mode of Nutrition
4. Multiplication by fragmentation

Which one of the following is a correct statement?

1. Pteridophyte gametophyte has a protonemal and leafy stage.
2. In gymnosperms, female gametophyte is free-living.
3. Antheridiophores and archegoniophores are present in pteridophytes.
4. Origin of seed habit can be traced in pteridophytes.

Cycas and Adiantum resemble each other in having

1. seeds
2. motile sperms
3. cambium
4. vessels

Selaginella and Salvinia are considered to represent a significant step toward evolution of seed habit because

1. female gametophyte is free and gets dispersed like seeds.
2. female gametophyte lacks archegonia.
3. megaspores possess endosperm and embryo surrounded by seed coat.
4. embryo develops in female gametophyte which is retained on parent sporophyte.
