  2. Biological organisation - Wikipedia

    en.wikipedia.org/wiki/Biological_organisation

    Multiple macromolecules form a cell, like a club cell. A group of cells functioning together as a tissue, for example, Epithelial tissue. Different tissues make up an organ, like a lung. Organs work together to form an organ system, such as the Respiratory System. All of the organ systems make a living organism, like a lion.

  3. Biological system - Wikipedia

    en.wikipedia.org/wiki/Biological_system

    A biological system is a complex network which connects several biologically relevant entities. Biological organization spans several scales and are determined based different structures depending on what the system is. [1] Examples of biological systems at the macro scale are populations of organisms.

  4. Staff and line - Wikipedia

    en.wikipedia.org/wiki/Staff_and_line

    Conflict can occur when the scopes of work and position roles & responsibilities are not clearly defined and enforced between line and staff functionaries. Decision making can be delayed or strained if executives of the staff function are misinterpreted or if the balance of structural power is not properly aligned between line functions, staff ...

  5. Organ system - Wikipedia

    en.wikipedia.org/wiki/Organ_system

    Plants have two major organs systems. Vascular plants have two distinct organ systems: a shoot system, and a root system. The shoot system consists stems, leaves, and the reproductive parts of the plant (flowers and fruits). The shoot system generally grows above ground, where it absorbs the light needed for photosynthesis. The root system ...

  6. Organizational theory - Wikipedia

    en.wikipedia.org/wiki/Organizational_theory

    Organizational theory covers both intra-organizational and inter-organizational fields of study. In the early 20th century, theories of organizations initially took a rational perspective but have since become more diverse. In a rational organization system, there are two significant parts: Specificity of Goals and Formalization.

  8. Organ (biology) - Wikipedia

    en.wikipedia.org/wiki/Organ_(biology)

    Two or more organs working together in the execution of a specific body function form an organ system, also called a biological system or body system. An organ's tissues can be broadly categorized as parenchyma, the functional tissue, and stroma, the structural tissue with supportive, connective, or ancillary functions.

  9. Biology - Wikipedia

    en.wikipedia.org/wiki/Biology

    Biologists can study life at multiple levels of organization, [1] from the molecular biology of a cell to the anatomy and physiology of plants and animals, and the evolution of populations. [1] [6] Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use.
