Single Celled Organism

Cell signalling lies at the heart of many biological processes and currently is the focus of intense research interest. In multicellular organisms, it is central to how different types of cell communicate with each other and how they detect and respond to extracellular signals. Intercellular communication is vital to single-celled organisms as well, allowing them to respond to environmental cues and signals. To date, much of the understanding of signalling mechanisms has come from research on specific cell types (eg mouse lymphocyte and cardiomyocyte) or on organisms in which communication systems such as nervous and endocrine systems are well established. This volume therefore aims to 'fill the gap' by concentrating on 'simple organisms' where the elements of those signalling systems first evolved. Many of the groups covered contain important pathogens or parasites, and the potential for manipulating signalling pathways for therapeutic intervention will be highlighted.

Single-Celled Organisms

Coral bleaching - Coral bleaching results when the symbiotic zooxanthellae (single-celled algae) are released from the original host coral organism due to stress. The corals that form the structure of the great reef ecosystems of tropical seas depend on these symbiotic photosynthesizing unicellular algae called "zooxanthellae" that live within their tissues.

Microorganism - A microorganism or microbe is an organism that is so small that it is microscopic (invisible to the naked eye). Microorganisms are often illustrated using single-celled, or unicellular organisms; however, some unicellular protists are visible to the naked eye, and some multicellular species are microscopic. The study of microorganisms is called microbiology.

Chlorella - Chlorellae is a collective name for a single celled algae. It is about 2 to 10 μm and is a circular organism.

Amoeba (Star Trek) - In the fictional Star Trek universe, the "Amoeba" is an alien lifeform encountered in the original Star Trek episode "The Immunity Syndrome". It is a space-borne single-celled organism that dwarfs the USS Enterprise (NCC-1701).

Cell Life Molecule Order Organism Way - Cell Life Molecule Order Organism Way Programmed cell death - Programmed cell death (PCD) is the deliberate suicide of an unwanted cell in a multicellular organism. In contrast to necrosis, which is a form of cell death that results from acute tissue injury and provokes an inflammatory response, PCD is carried out in a regulated process that generally confers advantages during an organism's life cycle. Multicellular organism - Multicellular organisms are those organisms consisting of more than one cell, and having differentiated ...

Nitrogen Containing Organic Compound - Nitrogen Containing Organic Compound Heterocyclic compound - Heterocyclic compounds are organic compounds that contain a ring structure containing atoms in addition to carbon, such as sulfur, oxygen or nitrogen, as part of the ring. They may be either simple aromatic rings or non-aromatic rings. Organic compound - An organic compound is any member of a large class of chemical compounds whose molecules contain carbon, with the exception of carbides, carbonates, carbon oxides and gases containing carbon.The study of organic compounds is ...

The explants are disinfected, and placed on a medium of growth. The genetic manipulation of plants has been machine-translated from Italian, and the English version has been machine-translated from Italian, and the English version has been only partially checked. The medium is also sterilized to avoid the rapid growth of the plant that, once fallen to earth, are able to take root. The cells will begin to form buds, which can be further separated and cultivated for a new cycle of propagation. Micropropagation The use of plant propagation we find scions and layerings, which are really shoots produced by asexual (agamic) reproduction of the plants, is the purpose of modern biotechnology. Scientific developments have allowed new techniques, mostly used today for producing many plants from a single one with particular characteristics. The original plant does not need to be destroyed. The result of the parent -- that is to single celled organism.
