Morphogenesis and Polarity of Tubular Cells with Tip Growthhis specialized treatment of cell morphogenesis is best explained through an examination of tip growth, the locally restricted enlargement of a cell that usually has a tubulär shape (F.-W. 1959). Tip growth is associated with polar, local secretion of wall material and represents a conspicuous examp

Such events occur in sequence during the life of an individual cell, and, in multicellular tissues and organs, are co-ordinated so that the population of cells dev

Morphogenesis of Tracheary Elements and Guard Cellsnd places in which a cell will strain in response to the internally generated turgor stress (Green 1980). To understand morphogenesis one must explain the mechanism of cell wall formation and in particular how unique patterns of cellulose reinforcements arise. Two cell types that possess specific wa

Sporogenesis and Pollen Grain Formationacterized by a highly ordered cell wall, the so-called sporoderm (Figs. 1 and 2). Both the chemical and the principal ultrastructural features of sporoderms show little Variation in different taxa, although the sculpture, number, and thickness of the individual wall layers display species-specificit

Ionic Currents as Control Mechanism in Cytomorphogenesisr these patterns. Therefore, a cell needs additional information for its proper spatial development to indicate, for instance, in which direction it should grow or in which plane it should divide. This information generally comes from external physical factors such as light, gravity, or pressure or

Pattern Formation in ,es that their shape as such, or the individual structural elements into which the organisms can be dissected, deviate to a great extent from basic geometric structures. Such basic structures are, for example, spheres, ellipsoids, or round columns with hemispheres attached to both ends.
