  2. Cell (biology) - Wikipedia

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

    The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.

  3. Cellular model - Wikipedia

    en.wikipedia.org/wiki/Cellular_model

    Part of the Cell cycle. A cellular model is a mathematical model of aspects of a biological cell, for the purposes of in silico research.. Developing such models has been a task of systems biology and mathematical biology.

  4. Cell biology - Wikipedia

    en.wikipedia.org/wiki/Cell_biology

    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 ...

  5. Cellular algebra - Wikipedia

    en.wikipedia.org/wiki/Cellular_algebra

    A cell-chain (and in fact the only cell chain) is given by 0 ⊆ R d × d {\displaystyle 0\subseteq R^{\!d\times d}} In some sense all cellular algebras "interpolate" between these two extremes by arranging matrix-algebra-like pieces according to the poset Λ {\displaystyle \Lambda } .

    Quizlet was founded in 2005 by Andrew Sutherland as a studying tool to aid in memorization for his French class, which he claimed to have "aced". [6] [7] [8] ...

  7. Cell growth - Wikipedia

    en.wikipedia.org/wiki/Cell_growth

    Cell growth refers to an increase in the total mass of a cell, including both cytoplasmic, nuclear and organelle volume. [1] Cell growth occurs when the overall rate of cellular biosynthesis (production of biomolecules or anabolism) is greater than the overall rate of cellular degradation (the destruction of biomolecules via the proteasome, lysosome or autophagy, or catabolism).

  8. List of unsolved problems in biology - Wikipedia

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    Developmental psychobiology posed this question since the lack of knowledge about the precise coordination of all cells, even those not related anatomically, in space and time during the embryonic period does not allow us to understand what forces at the cellular level coordinate four very general classes of tissue deformation, namely: tissue ...

  9. Cell theory - Wikipedia

    en.wikipedia.org/wiki/Cell_theory

    In biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.
