Input: Context: Symbiosis ( from Greek  `` together '' and  `` living '' ) is close and often long - term interaction between two different biological species . In 1877 Albert Bernhard Frank used the word symbiosis ( which previously had been used to depict people living together in community ) to describe the mutualistic relationship in lichens . In 1879 , the German mycologist Heinrich Anton de Bary defined it as `` the living together of unlike organisms . '' The definition of symbiosis has varied among scientists . Some believe symbiosis should only refer to persistent mutualisms , while others believe it should apply to any type of persistent biological interaction ( in other words mutualistic , commensalistic , or parasitic ) . After 130 years of debate , current biology and ecology textbooks now use the latter `` de Bary '' definition or an even broader definition ( where symbiosis means all species interactions ) , with the restrictive definition no longer used ( in other words , symbiosis means mutualism ) . Some symbiotic relationships are obligate , meaning that both symbionts entirely depend on each other for survival . For example , many lichens consist of fungal and photosynthetic symbionts that can not live on their own . Others are facultative ( optional ) : they can , but do not have to live with the other organism . Symbiotic relationships include those associations in which one organism lives on another ( ectosymbiosis , such as mistletoe ) , or where one partner lives inside the other ( endosymbiosis , such as lactobacilli and other bacteria in humans or Symbiodinium in corals ) . Symbiosis is also classified by physical attachment of the organisms ; symbiosis in which the organisms have bodily union is called conjunctive symbiosis , and symbiosis in which they are not in union is called disjunctive symbiosis ., Interaction is a kind of action that occurs as two or more objects have an effect upon one another. The idea of a two-way effect is essential in the concept of interaction, as opposed to a one-way causal effect. A closely related term is interconnectivity, which deals with the interactions of interactions within systems: combinations of many simple interactions can lead to surprising emergent phenomena. "Interaction" has different tailored meanings in various sciences. Changes can also involve interaction., The term "microbiologist" comes from the Greek "mkros" meaning "small" , and "bios", meaning "life" , combined with "-logia" meaning one who studies. A microbiologist (from Greek ) is a biological scientist who studies microscopic life forms and processes or works in the field of microbiology. Microbiologists investigate the growth, interactions and characteristics of microscopic organisms such as bacteria, algae, fungi, and some types of parasites and their vectors. They contribute much to the field by trying to understand and learn about the interaction between these microbes and the environment and also among themselves and other organisms. Most microbiologists are qualified to work in offices and/or research facilities, such as a laboratory as well as in the academia. There, they conduct experiments that help them analyze microbes and their importance. A microbiologist's work is often repeated or improved in order to establish accurate research. Most microbiologists specialize in environmental, food, agricultural, industrial or medical aspects of microbiology including: virology (the study of viruses); immunology (the study of mechanisms that fight infections); bioinformatics (the methods for storing, retrieving, organizing and analyzing biological data) and Bioremediation (using microbes as environmental mitigation strategies). Many microbiologists use biotechnology to advance the understanding of cell reproduction and human disease. Some microbiologists have contributed to knowledge of pathogens and disease-causing microbes. While others, study their interaction with the environment and their use as potential environmental pollution cleaners. , In biology, a species (abbreviated sp., with the plural form species abbreviated spp.) is the basic unit of biological classification and a taxonomic rank. A species is often defined as the largest group of organisms in which two individuals can produce fertile offspring, typically by sexual reproduction. While this definition is often adequate, looked at more closely it is often problematic. For example, in a species complex, the boundaries between closely related species become unclear or disappear altogether. Other ways of defining species include similarity of DNA, morphology, or ecological niche. The presence of locally adaptive traits may further subdivide species into infraspecific taxa such as subspecies., Deoxyribonucleic acid (DNA) is a molecule that carries the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses. DNA and RNA are nucleic acids; alongside proteins, lipids and complex carbohydrates (polysaccharides), they are one of the four major types of macromolecules that are essential for all known forms of life. Most DNA molecules consist of two biopolymer strands coiled around each other to form a double helix., In biology, a species complex is a group of closely related species that are very similar in appearance to the point that the boundaries between them are often unclear. Terms sometimes used synonymously but with more precise meanings are: cryptic species for two or more species hidden under one species name, sibling species for two cryptic species that are each other's closest relative, and species flock for a group of closely related species living in the same habitat. As informal taxonomic ranks, species group, species aggregate, and superspecies are also in use., Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, evolution, distribution, identification and taxonomy. Modern biology is a vast and eclectic field, composed of many branches and subdisciplines. However, despite the broad scope of biology, there are certain general and unifying concepts within it that govern all study and research, consolidating it into single, coherent field. In general, biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the synthesis and creation of new species. It is also understood today that all the organisms survive by consuming and transforming energy and by regulating their internal environment to maintain a stable and vital condition known as homeostasis., In ecology, a niche is a term with a variety of meanings related to the behavior of a species living under specific environmental conditions. The ecological niche describes how an organism or population responds to the distribution of resources and competitors (for example, by growing when resources are abundant, and when predators, parasites and pathogens are scarce) and how it in turn alters those same factors (for example, limiting access to resources by other organisms, acting as a food source for predators and a consumer of prey). "The type and number of variables comprising the dimensions of an environmental niche vary from one species to another [and] the relative importance of particular environmental variables for a species may vary according to the geographic and biotic contexts"., In biological classification, subspecies (abbreviated "subsp." or "ssp."; "plural": "subspecies") is either a taxonomic rank subordinate to species, or a taxonomic unit in that rank. A subspecies cannot be recognized independently: a species will either be recognized as having no subspecies at all or at least two (including any that are extinct)., In biology, offspring are the young born of living organisms, produced either by a single organism or, in the case of sexual reproduction, two organisms. Collective offspring may be known as a brood or progeny in a more general way. This can refer to a set of simultaneous offspring, such as the chicks hatched from one clutch of eggs, or to all the offspring, as with the honeybee., In biological classification, rank is the relative level of a group of organisms (a taxon) in a taxonomic hierarchy. Examples of taxonomic ranks are species, genus, family, order, class, phylum, kingdom, domain, etc., Heinrich Anton de Bary (26 January 183119 January 1888) was a German surgeon, botanist, microbiologist, and mycologist (fungal systematics and physiology).
He is considered a founding father of plant pathology (phytopathology) as well as the founder of modern mycology. His extensive and careful studies of the life history of fungi and contribution to the understanding of algae and higher plants were landmarks of biology.

Each gamete contains half the number of chromosomes of normal cells. They are created by a specialized type of cell division, which only occurs in eukaryotic cells, known as meiosis. The two gametes fuse during fertilization to produce DNA replication and the creation of a single-celled zygote which includes genetic material from both gametes. In a process called genetic recombination, genetic material (DNA) joins up so that homologous chromosome sequences are aligned with each other, and this is followed by exchange of genetic information. Two rounds of cell division then produce four daughter cells with half the number of chromosomes from each original parent cell, and the same number of chromosomes as both parents, though self-fertilization can occur. For instance, in human reproduction each human cell contains 46 chromosomes, 23 pairs, except gamete cells, which only contain 23 chromosomes, so the child will have 23 chromosomes from each parent genetically recombined into 23 pairs. Cell division initiates the development of a new individual organism in multicellular organisms, including animals and plants, for the vast majority of whom this is the primary method of reproduction., In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs., Subject: symbiosis, Relation: instance_of, Options: (A) acid (B) action (C) animal (D) bacteria (E) biology (F) biopolymer (G) bioremediation (H) bios (I) classification (J) collective (K) complex (L) concept (M) condition (N) degree (O) division (P) dna (Q) enterprise (R) exchange (S) extinct (T) field (U) four (V) gamete (W) genus (X) hierarchy (Y) history (Z) human disease ([) idea (\) information (]) january (^) material (_) may (`) molecule (a) name (b) natural science (c) organism (d) plant (e) point (f) population (g) rank (h) reproduction (i) scale (j) science (k) set (l) single (m) species (n) structure (o) system (p) systematics (q) taxon (r) taxonomic rank (s) taxonomy (t) term (u) two (v) understanding (w) variety (x) work
