In this article we will discuss about the gametophytic phase, reproduction and sporophytic phase in the life cycle of pogonatum. This will also help you to draw the life cycle of pogonatum. Gametophytic Phase of Pogonatum : (i) External Features of Gametophyte: The plants are perennial, erect gametophytes and can be differentiated into two regions: (a) Rhizome (b) Rhizoids (a) [...]
In this article we will discuss about the structure of Pogonatum with the help of diagrams. External Features of Pogonatum: The gametophyte is perrenial, differentiates into a rhizomatous basal portion and aerial upright shoots (Fig. 6.54A). The basal portion bears numerous rhizoids. The rhizoids are multicellular, elongated, thick-walled with oblique septa and are twisted together in a rope-like manner to [...]
In this article we will discuss about the vegetative and sexual modes of reproduction in Pogonatum. Vegetative Reproduction in Pogonatum: Vegetative propagation of Pogonatum takes place by the following methods: Gemmae: Bud-like gemmae develop on the rope-like rhizoids and each gemma forms a gametophyte after germination. Secondary Protonema: The secondary protonema develops from any part of the plant other than [...]
