A cellular business structure is partly related, philosophically speaking, to the notion of 'spontaneous order' described by prominent Austrian–British social theorist F. A. Hayek. The theory posits that free association and open access to up-to-date information will lead to individuals naturally creating and sustaining social groups to co ...
Cell: Basic unit of all life and the grouping of organelles Super-cellular level (Multicellular level) Tissue: Functional groups of cells Organ: Functional groups of tissues Organ system: Functional groups of organs Ecological levels: Organism: The basic living system, a functional grouping of the lower-level components, including at least one ...
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional ...
The term 'molecular biology' was first used in 1945 by the English physicist William Astbury, who described it as an approach focused on discerning the underpinnings of biological phenomena—i.e. uncovering the physical and chemical structures and properties of biological molecules, as well as their interactions with other molecules and how ...
The microtubule-organizing center (MTOC) is a structure found in eukaryotic cells from which microtubules emerge. MTOCs have two main functions: the organization of eukaryotic flagella and cilia and the organization of the mitotic and meiotic spindle apparatus, which separate the chromosomes during cell division.
Molecular Biology of the Cell has been described as "the most influential cell biology textbook of its time". [2] The sixth edition is dedicated to the memory of co-author Julian Lewis, who died in early 2014. The book was the first to position cell biology as a central discipline for biology and medicine, and immediately became a landmark ...
Cell physiology is the biological study of the activities that take place in a cell to keep it alive. The term physiology refers to normal functions in a living organism . [ 1 ] Animal cells , plant cells and microorganism cells show similarities in their functions even though they vary in structure.
Another hypothesis is that a primitive cell underwent nucleus division, thereby becoming a coenocyte. A membrane would then form around each nucleus (and the cellular space and organelles occupied in the space), thereby resulting in a group of connected cells in one organism (this mechanism is observable in Drosophila). A third hypothesis is ...
