Answer 1

Funaria is a genus of approximately 210 species of moss. Funaria hygrometrica is the most common species. Funaria hygrometrica is called “cord moss” because of the twisted seta which is very hygroscopic and untwists when moist. The name is derived from the Latin word “funis”, meaning a rope.

Juvenile stage represented by primary protonema and

(ii) The leafy gametophore which represents the adult form.

The adult gametophyte (gametophore) is differentiated into rhizoids, axis or ‘stem’ and ‘leaves’ (Fig. 1 A). Rhizoids arise from the base of the axis. They are slender, branched, and multicellular and have oblique septa.

Axis is 1—3 cm. high, upright, slender and branched. Each branch is extra axillary i.e., arise below a leaf. Leaves are sessile, oblong-ovate with entire margin, pointed apex and are arranged spirally on the branches and ‘stem’. Each ‘leaf’ is traversed by a single mid rib (Fig. 1B). ‘Leaves’ are borne in 1/3 phyllotaxy which becomes 3/8 at maturity.
