In this article we will discuss about the gametophytic phase, reproduction and sporophytic phase in the life cycle of riccia. Gametophytic Phase of Riccia: The plant body of Riccia is gametophytic and gametophytes are fleshy, prostrate and dichotomously branched. Repeated dichotomy results into a typically rosette like appearance (Figs. 1, 3). In Riccia cruciata only two dichotomy result in a [...]
In this article we will discuss about:- 1. External Features of Riccia 2. Anatomy of Gametophyte in Riccia 3. Sex Organs. External Features of Riccia: Study dorsal and ventral surface of the thallus; separate scales and mount in glycerine; also separate rhizoids from the ventral surface, stain in safranin, mount in glycerine and study: 1. Gametophytic plant body is thalloid, [...]
In this article we will discuss about the structure of Riccia with the help of diagrams. External Structures of Riccia: The gametophytic plant body of Riccia is a dichotomously branched dorsiventral prostrate thallus. In terrestrial habits, the plants usually occur in a rosette form due to the presence of a number of dichotomies that grow together from one place (Fig. [...]
