bacteria to those of eukaryotic microorganisms: a ..

Cyanobacteria account for 20–30% of Earth's photosynthetic productivity and convert solar energy into biomass-stored chemical energy at the rate of ~450 TW. Cyanobacteria utilize the energy of sunlight to drive photosynthesis, a process where the energy of light is used to split water molecules into oxygen, protons, and electrons. While most of the high-energy electrons derived from water are utilized by the cyanobacterial cells for their own needs, a fraction of these electrons are donated to the external environment via electrogenic activity. Cyanobacterial electrogenic activity is an important microbiological conduit of solar energy into the biosphere.

Plants cells contain a number of structures that are involved in the process of photosynthesis:

What kingdoms of living organisms contain eukaryotic cells

There are three domains of life: Bacteria (also known as Eubacteria), Archaea, and Eukarya. The Bacteria and Archaea are made up entirely of microorganisms; the Eukarya contains plants, animals, and microorganisms such as fungi and protists. The Bacteria and Archaea have been grouped together and called Prokaryotes because of their lack of a nucleus, but the Archaea are more closely related to the Eukaryotes than to the Bacteria. Here are other major differences between the three domains.

Aerobioc Respiration and Photosynthesis essays

There are two main types of photosynthesis: (the kind that generates O2) and (the kind that doesn’t generate O2). Anoxygenic photosynthesis is used mainly by the purple bacteria, the green sulfur and nonsulfur bacteria, the heliobacteria and the acidobacteria. Oxygenic photosynthesis is used by the cyanobacteria, the algae, and by plants.

The society’s “Portal to Protistology” provides an extensive list of links and other resources for learning more about microorganisms. Some sections of the site contain information for educators, students, and researchers. The “for fun” section includes images, songs, and trivia.


Sometimes organisms are discovered that have no apparent relationship to the rest of eukaryotic life. Trimastix, which lives in the sediments of lakes and oceans, is a good example. This organism, first described in 1886, but was practically forgotten and not studied until the late 1990s. It has no mitochondria but it has been suggested that it possesses a vestigial one. Trimastix shares a number of characteristics with a loose assemblage of parasites and marine organisms called the excavates. Some of the excavates also have no mitochondria, while others have mitochondria that most closely resemble what we think the original mitochondrion looked like. At one time it was thought that those excavates without mitochondria might even be ancient lineages that evolved before the ancestor of the rest of eukaryotes captured the original mitochondria.3 However, scientists now believe most of those excavates have probably had mitochondria at one time and then lost them.20

What is the difference in photosynthesis and respiration in eukaryotic microorganisms and bacteria?

Cellular Respiration and Bioremediation Breathing ..

Microbiological research has demonstrated that there are currently five known branches of microorganisms that are capable of undertaking chlorophyll based photosynthesis. These five branches are purple bacteria (i.e. Rhodobacter ), green sulfur bacteria (i.e. Chlorobium ), green gliding bacteria (i.e. Chloroflexus ), the Gram positive organism Heliobacteria, and the oxygen evolving cyanobacteria (i.e. Synechococcus ). Cyanobacteria are the only known bacterial group that are capable of evolving oxygen as a byproduct of photosynthesis. Phylogenetic analyses indicate that cyanobacteria are closely related to plant and algal chloroplasts which is the organelle that houses the photosystem in eukaryotic cells.

The unicellular cyanobacterium Synechocystis sp. PCC6803 was the third prokaryote and first photosynthetic organism whose genome was completely sequenced. It continues to be an important model organism. The smallest genomes have been found in Prochlorococcus spp. (1.7 Mb) and the largest in Nostoc punctiforme (9 Mb). Those of Calothrix spp. are estimated at 12–15 Mb, as large as yeast.

Advanced Bioinformatics: Genetic Research
This curriculum unit explores how bioinformatics is used to perform genetic research. Students examine DNA sequences from different animal species, investigate the relationship between protein structure and function, and explore evolutionary relationships among eukaryotic organisms. Throughout the unit, students are presented with a number of career options in which the tools of bioinformatics are developed or used.
