Retained Earnings. The accumulated profits of a corporation that are not paid out as dividends. Instead, the money is reinvested in the core business or used to pay off debt. Also called accumulated earnings or earned surplus.
In cell biology, molecular biology and related fields, the word intracellular means inside the cell. It is used in contrast to extracellular (outside the cell). The cell membrane (and, in many organisms, the cell wall) is the barrier between the two, and chemical composition of intra- and extracellular milieu (Milieu intÃ©rieur) can be radically different.
A cell junction (or intercellular bridge) is a type of structure that exists within the tissue of some multicellular organisms, such as animals.Cell junctions consist of multiprotein complexes that provide contact between neighbouring cells or between a cell and the extracellular matrix.nvertebrates have several other types of specific junctions, for example septate junctions or the C. elegans apical junction. In multicellular plants, the structural functions of cell junctions are instead provided for by cell walls. The analogues of communicative cell junctions in plants are called plasmodesmata.
