In this article we will discuss about the structure of Lycopodium with the help of diagrams. The main plant body is sporophytic. It conÂsists of slender and branched stem, numerous small leaves (microphylls) and dichotomously- branched roots (Fig. 7.23A, B). Roots: The primary root or first formed root of the young sporophyte is ephemeral, short-lived. The older plants have dichotomously [...]
In this article we will discuss about the structure and reproduction in Dryopteris. Structure of Dryopteris: Sporophyte: The sporophytic plant body is differentiated into roots, rhizomatous stem and leaves (Fig. 7.111 A). 1. Root: The primary root is ephemeral, and is replaced by a large number of adventitious roots growing from the leaf bases. The roots are small and branched. [...]
In this article we will discuss about the structure and reproduction in Pteris. Structure of Pteris: Sporophyte: The main sporophytic plant body is differenÂtiated into root, rhizomatous stem and leaves (Fig. 7.102A). 1. Root: The primary root is ephemeral, and is replaced by a large number of adventitious roots developed all over the surface of the rhizome. The roots are [...]
