In this article we will discuss about the structure and reproduction in Isoetes with the help of diagrams. Structure of Isoetes: Sporophyte: The plant resembles a monocot garlic plant in particular (Fig. 7.59). Isoetes is commonly called 'Quill wort' due to the quill (a large feather)-like structure of the leaves. The plant body consists of a condensed, lobed corm or [...]
In this article we will discuss about the structure of Lycopodium with the help of diagrams. The main plant body is sporophytic. It consists 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. [...]
