Heterospory and ligulate leaves in Selaginella
Heterospory:
- Selaginella is a genus of plants known as spike-mosses, which exhibit heterospory.
- Heterospory is a characteristic feature where plants produce two types of spores: microspores and megaspores.
- Microspores develop into male gametophytes, while megaspores develop into female gametophytes.
Ligulate leaves:
- Selaginella plants also have ligulate leaves, which are strap-shaped leaves with a narrow base and a broad apex.
- These leaves are typically arranged spirally along the stems of the plant.
- Ligulate leaves help in photosynthesis and serve as protective coverings for the reproductive structures of the plant.
Therefore, Selaginella is the correct option among the given choices as it exhibits both heterospory and ligulate leaves.
