Which kingdoms are prokaryotic

Division Pterophyta ferns. Division Cycadophyta cycads. Division Ginkgophyta maidenhair tree. Division Coniferophyta Pinophyta: conifers. Division Anthophyta flowering plants. Biological Organization. Species a distinct kind or unit. Twenty of the more than species of Pinus on earth. All of these pines are native to the state of California, USA.

Monterey Pine P. Bishop Pine P. Santa Cruz Island Pine P. Whitebark Pine P. Limber Pine P. Beach Pine P. Lodgepole Pine P. Western White Pine P. Knobcone Pine P.

Bristlecone Pine P. Foxtail Pine P. Four-Leaf Pinyon P. Two-Leaf Pinyon P. One-Leaf Pinyon P. Ponderosa Pine P. Coulter Pine P. Digger Pine P. Torrey Pine P. Jeffrey Pine P. Sugar Pine P. Another species left image called the Washoe Pine P. In addition, the Beach and Lodgepole Pines are now recognized as subspecies of P.

According to R. Lanner Conifers of California , , there may be other significant changes in the pines of California. Allozyme studies in two-leaf pinyons Pinus edulis of the New York Mountains indicate that these populations are biochemically and genetically consistent with nearby one-leaf pinyon Pinus monophylla , and that P. The unusual New York Mountains population appears to be a 2-needle variant of P.

According to Lanner, the latter species has five needles per fascicle and occurs in San Diego County. The hybrid hypothesis might explain the perplexing variation in needle number for P. The domain Bacteria comprises all organisms in the kingdom Bacteria, the domain Archaea comprises the rest of the prokaryotes, and the domain Eukarya comprises all eukaryotes—including organisms in the kingdoms Animalia, Plantae, Fungi, and Protista.

Two of the three domains—Bacteria and Archaea—are prokaryotic. Prokaryotes were the first inhabitants on Earth, appearing 3. There are thousands of known species of eubacteria, though they are generally subdivided by their shapes: rod, spiral and spherical.

Eubacteria are important to the global ecosystem because they break down dead organic material into nitrogen, which is then returned to the atmosphere and used to fertilize plants.

The Archaea Kingdom is a relatively new prokaryotic kingdom, and its organisms differ from the eubacteria because of the environment in which they live. Archaea differ from almost all other forms of life because they can survive in extreme environments, such as at the bottom of sea vents or in acidic water. Like eubacteria, there is a large variety of Archaea species, with some possessing abilities not found in any other organisms, such as the Halobacterium, which uses salt water to power a proton pump that gives it energy.

Despite their similarities to eubacteria and Archaea, viruses are not considered prokaryotic organisms, and thus they do not have their own kingdom. We hope you enjoyed your reading.
