In this article we will discuss about the gametophytic phase, reproduction and sporophytic phase in the life cycle of funaria. Gametophytic Phase of Funaria: (i) External Features: Plant body is gametophytic and consists of two different stages namely: (i) Juvenile stage represented by primary protonema and (ii) The leafy gametophore which represents the adult form. The adult gametophyte (gametophore) is [...]
In this article we will discuss about the external features of funaria. 1. Plant body is gametophytic, and each gametophore consists of rhizoids, 'stem' and ‘leaves’ (Fig. 194). 2. Each gametophore is slender, erect and attains a height of 1 to 3 cm or more. 3. Rhizoids arise from the base of the 'stem' in the form of tufts. 4. [...]
In this article we will discuss about the anatomy of funaria. Cut transverse sections of axis and leaf, stain them in safranin, mount in glycerine and study under microscope. T.S. Axis: 1. Internally, there is no much specialization of cells. The axis or stem is differentiated into three different regions, i.e., epidermis, cortex and conducting strand or medulla (Fig. 197A). [...]
