Clubmoss (Lycopodium) Structure & Life Cycle Carlson Stock Art

Lycopodium is homosporous and the spores are produced within large, short-stalked, reniform to somewhat sub-globose sporangia, borne singly either in the axils or on the stem, a little above the sporophylls.

ADVERTISEMENTS: 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: ADVERTISEMENTS: The primary root or first formed root of the young sporophyte is […]

is simply a terminal shoot. The central stem bears leaves each with a sporangium. While observing through a dissecting microscope, pull leaves off the stem using teasing needles. Identify megasporophylls bearing megasporangia and microsporophylls bearing microsporangia. Crush each type of sporangium and compare the relative size of each spore.

1. Plant body is sporophytic and the sporophyte is divisible into roots, stem and leaves (Fig. 224). 2. The genus is divisible into two subgenera, i.e., Urostachya and Rhopalostachya.

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 of a.

Lycopodium (from Greek lykos, wolf and podion, diminutive of pous, foot) [2] is a genus of clubmosses, also known as ground pines or creeping cedars, [3] in the family Lycopodiaceae. Two very different circumscriptions of the genus are in use.

Figure 6.1.1. 1: A preserved Lycopodium gametophyte. The flat thallus extending out to the right is the gametophyte. The sporophyte emerges from its left side, the root system developing downward and shoot system developing upward. This gametophyte would normally be green and photosynthetic, but the pigments were lost in the preservation process.

This is a diagram of a section through the node (where the leaf emerges from the stem). The space in the siphonostele is called a leaf gap. It represents where vascular tissue has branched off into the leaf. (b) Dictyostele= with large, overlapping leaf gaps which dissect the vascular system into a network.

Observe fresh specimens and prepared slides of Selaginella and/or Lycopodium. Draw and describe the important characteristics that differentiate these plants from bryophytes, including stem and leaf structure, below ground parts, and where spores are produced.

Lycopodium cernuum Strobili. Plant body is the sporophyte. Differentiated into root, stem and leaves. Considering the variation in habit of different species, Pritzel (1900) divided the genus Lycopodium into two sub-genera: Urostachya. Rhopalostachya. Erect or pendant stem. Stem-Dichotomously branched. Roots arise only from base of stem.

The Epidermis of the stem typically has Stomata. The outer Cortex usually contains Chlorenchyma. This photosynthetic tissue may contain a lot of air spaces & can be continuous with the leaves. The take home message is that the stems can make a major contribution to the total amount of photosynthesis that takes place in Lycopodium.

Asexual propogation of sporophytes can occur via an underground stem that travels horizontally, called a rhizome. Figure 2.5.3.1.3 2.5.3.1. 3: A Lycopodium sporophyte growing vegetatively. The branches occur in Y-formations, showing dichotomous branching. There are many small, thin leaves (microphylls).

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.
