In biology and botany, indeterminate growth is growth that is not terminated, in contrast to determinate growth that stops once a genetically predetermined structure has completely formed. Thus, a plant that grows and produces flowers and fruit until killed by frost or some other external factor is called indeterminate.
Modular organisms [3] have indeterminate growth forms (life stages not set) through repeated iteration of genetically identical modules (or individuals), and it can be difficult to distinguish between the colony as a whole and the modules within. [4] In the latter case, modules may have specific functions within the colony.
In organisms that breed multiple times and live in places where food availability and mortality change significantly on the basis of season, it is predicted that capital breeding will be more prevalent, as the time when the organism is not breeding but when conditions are still favourable will be dedicated to rebuilding stores, therefore allowing them to achieve higher rates of reproduction.
Most deuterostomes display indeterminate cleavage, in which the developmental fate of the cells in the developing embryo is not determined by the identity of the parent cell. Thus, if the first four cells are separated, each can develop into a complete small larva; and if a cell is removed from the blastula, the other cells will compensate.
A cell can only be indeterminate (also called regulative) if it has a complete set of undisturbed animal/vegetal cytoarchitectural features. It is characteristic of deuterostomes—when the original cell in a deuterostome embryo divides, the two resulting cells can be separated, and each one can individually develop into a whole organism.
Growth mostly occurs through cell proliferation but also through changes in cell size or the deposition of extracellular materials. The development of plants involves similar processes to that of animals. However, plant cells are mostly immotile so morphogenesis is achieved by differential growth, without cell movements.
Libido, or sex drive, may seem like something people are just born with — either you have a high sex drive, or you don’t.Yet many things can have an impact on one’s libido, from physical ...
Growth of the stem is indeterminate in pattern (not pre-determined to stop at a particular point). [1] The functions of the stem are to raise and support the leaves and reproductive organs above the level of the soil, to facilitate absorption of light for photosynthesis , gas exchange, water exchange ( transpiration ), pollination , and seed ...
