These plants reproduce by producing spores on the surfaces of their leaves or in specialized cone-shaped structures. The initial cell undergoes perclinal division to form an outer primary cover cell and an inner central cell. The external resemblance of the sporophytic rhizome and gametophyte, coupled with the presence of vascular tissue in the gametophyte, supported the homologous theory on the origin of alternation of generation. They reproduce by microscopic spores, rather than by seeds as in flowering plants or conifers.

Like many other … However, recent comparative DNA analysis suggests that this group may have lost both leaves and roots through evolution and is more closely related to ferns. These small plants are like mosses but they have flattened bodies or stems and grow on rocks or the ground. The restoration of natural places encroached upon by human intervention, such as wetlands, also requires the Whorls of leaves and branches. Scientists have now learned how to germinate the spores of some species of Psilotum in the laboratory, allowing for a more complete study of their gametophytes. The inner primary androgonial divides in various planes and produces mass of developing androgonial cell, the last generation of which are the androcytes. There are over 8,500 species worldwide, often in moist areas, though there are some outliers . Huge collection, amazing choice, 100+ million high quality, affordable RF and RM images.

Be able to recognize the example seen in the jar (Psilotum) 1. Photosynthesis occurs in the aerial stems, and water and mineral absorption occurs in the horizontal underground rootlike stems (rhizomes), which receive water and nutrients from fungi through a mycorrhizal association. Since whisk ferns have no flowers or seeds, the plants reproduce by the spread of spores. Club mosses is used as medicine to . Spores are homosporous. Psilotum is a genus of fern-like vascular plants, commonly known as whisk ferns. Ferns reproduce using spores and are commonly known for their reproductive stages when the fern frons are on display. They are the nearest existing relative of …. Exoscopic: Having the apex of the embryo pointed toward the neck of the archegonium. Spore producing structure: At maturity many of the dichotomously branched aerial shoots become fertile and produce trilocular sporangia known as synangia. Ferns and fern allies share the same .
