In this article we will discuss about the anatomy of lycopodium. Also study the strobilus, arrangement of sporangia, L.S. strobilus and spores of lycopodium. Cut thin transverse sections of stem, leaf and root by inserting the material in pith, stain in safranin- fast green combination, mount in glycerine and study- under microscope. Stem: 1. Internally, the stem (Fig. 227) consists [...]
In this article we will discuss about the anatomy of equisetum. Also learn about its spore-producing organs. Cut thin transverse sections of different plant parts, stain in safranin-fast green combination, mount in glycerine and observe the anatomical details: T. S. Internode of Aerial Sterile Shoot: In a cross-section following structures are visible (Figs. 237,238): 1. It is wavy in outline [...]
In this article we will discuss about the anatomy of marsilea. Cut the transverse sections through different parts of the plant (rhizome, petiole, leaflet, and root), stain them separately in safranin-fast green combination, mount in glycerine and observe the anatomical details under microscope: Rhizome: 1. The outermost layer is epidermis which is continuous and without any stomata. 2. The cortex [...]
