In the domain of Eukaryotes, which constitute all organisms whose cells have a membrane-bound nucleus: there are many forms or Eukaryotes, including animals, plants, fungi, seaweeds and many unicellular organism. Furthermore, the plants are those eukaryotes that form the Kingdom Plantae and are predominantly photosynthetic, meaning that they obtain their energy from sunlight using chloroplasts.
The Kingdom of Plants is divided into five groups called Phylum of which plants are distributed over the entire earth, both on land and under the waters.
The phylum are listed to the left in the menu under The Plants. To learn more about these plants, please feel free to explore.
Gymnosperm Characterists:
1. Vascular
organisms with a channel or system of channels for carrying fluids.
2. Seed Producing
Gymnosperm organisms are seed producing.
3. Non-flowering
In their development of seeds, the organisms are non-flowering.
Gymnosperm Information:
The word Gymnosperm comes from the Greek words: gymnos meaning naked and sperma meaning seed. Thus, these organisms produce seeds but are naked, meaning, the plants have no flowers.
Gymnosperm seeds develop on the surface of scales or leaves which form cones, or at the end of short stalks as in Ginkgo. The ovule is not enclosed in a sporophyte tissue when first formed but may be covered with a sporophte tissue at maturity.
The phylum Gymnosperm is the phylum with the smallest number of organisms, just 873 species, and this phylum is divided into four Classes.
