Funaria is anchored by multicellular, branched rhizoids that feature oblique septa.

The columella is a central, sterile column of tissue within the capsule of the Funaria sporophyte.

The peristome of Funaria consists of two concentric rings, each containing 16 teeth, for a total of 32 teeth.

• In the majority of bryophytes, embryonic sporophytes elongate gradually to form a foot and a spore-bearing capsule. Calyptra is an enlarged archegonial venter in bryophyte that protects the capsule containing the embryonic sporophyte.
• Columella is a column of sterile tissues which extends through the theca and are surrounded by spore-producing cells. Antheridium is the male sex organ of algae, fungi, ferns, and other nonflowering plants

Funaria spores contain chloroplasts, which allow them to begin photosynthesis immediately upon germination.

Spores are the first cells of the gametophytic generation in the moss life cycle, as they are haploid and germinate to form the protonema.

In Funaria, the rhizoids develop from the basal region of the gametophytic axis.

Acrocarpous mosses have their sex organs at the tips of the main axis or primary branches, leading to an upright growth habit.

The peristome is a characteristic structure found around the mouth of the capsule in mosses like Funaria, aiding in spore dispersal.

The sporophyte of Funaria is partially independent because it contains chlorophyll in the apophysis, allowing for some photosynthesis, though it remains dependent on the gametophyte for water and minerals.
