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 structure of Funaria with the help of a diagram. External Features of Funaria: The erect gametophytic plant (Fig. 6.47A) is about an inch high with an erect leafy axis or stem attached to the substratum by rhizoids. The axis is radial, often branched axillary or extra-axillary. The axis is covered with spirally [...]
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 [...]
