SYSTEMATICS
 
  • Adaptive Radiation : It is the process of evolution from a single ancestral species of a variety of forms which occupy somewhat different habitat
  • Ancestor : One from which an organism has descended.
  • Bacteriophage : A virus which multiples in a bacterial cell and lyses the cell in which it multiples.

  • Binomial nomenclature : Naming of an organism with two names, first word is generic name and the second is specific name.

  • Classification : It is a system of arrangement of organisms into group showing relationship.

  • Decomposer : It refers to the organisms that feed upon dead organisms breaking them down into simpler substances.

  • Eukaryotes : The organism having eukarotic cell are termed as eukaryotes.

  • Fungi : It is a diverse group of plants characterized by their lack of chlorophyll. They are generally saprophytic or parasites.

  • Genus : It is a group of species which resemble each other in their structural and functional character.

  • Identification : It is the determination of correct place or position occupied by an organism in the plan of classification.

  • Key : It is a method which provides a convenience for easy identification of an organism using important distinguished character.

  • Lichens : It is a group of composite plants which are symbiotic association between a green or blue green algae and a fungus.

  • Metazoa : It is a kingdom of multicellular animals whose bodies are composed of specialized cells grouped together to form tissues and to process a coordinating nervous system.

  • Nomenclature : The process of giving scientific names to animals and plants is called nomenclature.

  • Nucleoid : The region of a bacterium of blue green algae containing DNA and not enclosed by membranes.

  • Phylogeny : It refers to the evolutionary development of a species to other taxonomic groups.

  • Phylogeny : The evolutionary history of any group of organisms is termed as phylogeny.

  • Producers : The first trophic level in a food chain. Producers are those organisms that can produce food from inorganic material e.g. green plants.

  • Prokaryotes : The organism having prokaryotic cells (cells without a definite nuclear membrane around nuclear material).

  • Protista : A kingdom of unicellular eukaryotes.

  • Protista : It is a kingdom of unicellular eukaryotes.

  • Saprophytes : Organism living on decaying organic matter.

  • Species : The group at Individuals which resemble one another in structural and functional character, interbreed freely and truly among themselves and are thought to have originated from common ancestor.

  • Systematics : It is the specific study of the kinds and diversity of organisms and the relationship among them.

  • Taxon (Pl. Taxa) : A taxon is a group of real organism recognized as a formal unit as any level of a hierarchical classification.

  • Taxonomy : Texonomy is defined as the study of identification and classification of plants and animals.
