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 inflorescences these two different growth patterns are called indeterminate and determinate respectively, and indicate whether a terminal flower is formed and where flowering starts within the inflorescence. Indeterminate inflorescence: Monopodial (racemose) growth. The terminal bud keeps growing and forming lateral flowers.
The growth of nitrogen-fixing root nodules on legume plants such as soybean and pea is either determinate or indeterminate. Thus, soybean (or bean and Lotus japonicus) produce determinate nodules (spherical), with a branched vascular system surrounding the central infected zone.
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 ...
A panicle may have determinate or indeterminate growth. This type of inflorescence is largely characteristic of grasses, such as oat and crabgrass, [a] as well as other plants such as pistachio and mamoncillo.
A gap of only two or three years isn't much in the grand scheme of things but feels like a lot when you're thirteen, small for your age, with some indeterminate time until your growth spurt.
Tomato and potato cultivars are commonly classified as determinate or indeterminate according to the amount of time that they produce new leaves and flowers. Varieties that produce few leaves and flowers over a shorter period are classed as determinate and those that produce new leaves and flowers for longer are classed as indeterminate.
