  2. Cell plate - Wikipedia

    en.wikipedia.org/wiki/Cell_plate

    As the cell plate matures in the central part of the cell, the phragmoplast disassembles in this region and new elements are added on its outside. This process leads to a steady expansion of the phragmoplast and, concomitantly, to a continuous retargeting of Golgi-derived vesicles to the growing edge of the cell plate. Once the cell plate ...

  3. Feynman diagram - Wikipedia

    en.wikipedia.org/wiki/Feynman_diagram

    A closed loop is a cyclical path of adjacent vertices that never revisits the same vertex. Such a cycle can be thought of as the boundary of a hypothetical 2-cell. The k-labellings of a graph that conserve momentum (i.e. which has zero boundary) up to redefinitions of k (i.e. up to boundaries of 2-cells) define the first homology of a graph ...

  4. Phragmoplast - Wikipedia

    en.wikipedia.org/wiki/Phragmoplast

    The cell plate will transform into the new cell wall once cytokinesis is complete. The phragmoplast is a plant cell specific structure that forms during late cytokinesis . It serves as a scaffold for cell plate assembly and subsequent formation of a new cell wall separating the two daughter cells.

  5. Cellular automaton - Wikipedia

    en.wikipedia.org/wiki/Cellular_automaton

    A cellular automaton consists of a regular grid of cells, each in one of a finite number of states, such as on and off (in contrast to a coupled map lattice). The grid can be in any finite number of dimensions. For each cell, a set of cells called its neighborhood is defined relative to the specified cell.

  6. 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.

  7. 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.

  8. Septum (cell biology) - Wikipedia

    en.wikipedia.org/wiki/Septum_(cell_biology)

    This is because in a plant cell there is no cleavage furrow or pinching of the plasma membrane, rather a cell plate forms in the middle of the cell that then allows the division into two daughter cells. [6] The cell plate formation occurs due to vesicles budding from the golgi apparatus [7] and adding to the plant cell in a centrifugal manner ...

  9. Metaphase - Wikipedia

    en.wikipedia.org/wiki/Metaphase

    Stages of early mitosis in a vertebrate cell with micrographs of chromatids Metaphase (from Ancient Greek μετα- ( meta- ) beyond, above, transcending and from Ancient Greek φάσις (phásis) 'appearance') is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most condensed and coiled stage (they are ...
