Like all pteridophytes, the life cycle of Selaginella exhibits alternation of generations where the sporophyte is the dominant, independent, and photosynthetic phase.

The stem of Selaginella typically contains a protostele, which is the simplest type of stele consisting of a solid core of xylem surrounded by phloem.

The plant body of Selaginella is a sporophyte, which is diploid and produces spores through meiosis.

Selaginella bryopteris is widely identified as the plant known as Sanjeevani in Indian traditional medicine due to its resurrection properties.

Selaginella is considered to show a rudimentary seed habit because the megaspore is retained within the megasporangium and the female gametophyte develops while still attached to the parent plant.

The ligule is a small, scale-like outgrowth found on the adaxial surface of the leaves of Selaginella, which is a characteristic feature of the order Selaginellales.

Selaginella can reproduce vegetatively through various methods including fragmentation, tubers, and resting buds, which allow it to propagate effectively.

Heteromorphic alternation of generations refers to a life cycle where the sporophyte and gametophyte phases are morphologically distinct, which is characteristic of Selaginella.

The male gametes (antherozoids) of Selaginella are biflagellate, meaning they have two flagella to aid in swimming toward the archegonia.

Selaginella is known to possess pyrenoids in its chloroplasts, which is a unique feature among many pteridophytes.
