A developmental process by which a progressive change in the state of some part of an organism specifically contributes to its ability to form offspring. The directed movement of a motile cell or organism, or the directed growth of a cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis). The process by which the growth of pollen tube is directed towards the female gametophyte. The process whose specific outcome is the progression of a pollen tube over time, from its initial formation to a mature structure. The process whose specific outcome is the progression of a tube over time, from its initial formation to a mature structure. Epithelial and endothelial tubes transport gases, liquids and cells from one site to another and form the basic structure of many organs and tissues including lung and trachea, kidney, the mammary gland, the vascular system and the gastrointestinal and urinary-genital tracts. The cascade of biological processes occurring in plants beginning when the pollen lands on the stigma and continuing up to, but not including, fertilization, as defined by sperm-central cell fusion. The directed movement of a motile cell or organism, or the directed growth of a cell guided by a higher concentration, in a concentration gradient of a specific chemical.
