The term 'sucker' has also been used as well, especially for bromeliads, which can be short lived plants and when the parent plant has flowered, they signal the root nodes to form new plants. [ 1 ] Offsets form when meristem regions of plants, such as axillary buds or homologous structures, differentiate into a new plant with the ability to ...
The formation of woody tissue is an example of secondary growth, a change in existing tissues, in contrast to primary growth that creates new tissues, such as the elongating tip of a plant shoot. The process of wood formation (lignification) is commonest in the spermatophytes (seed bearing plants) and has evolved independently a number of times ...

Plant propagation is the process by which new plants grow from various sources, including seeds, cuttings, and other plant parts. Plant propagation can refer to both man-made and natural processes. Propagation typically occurs as a step in the overall cycle of plant growth.
The process is similar to the mechanism of stomatal closure. Common examples for pulvinar movements include the night closure movement of legume leaves and the touch response of the sensitive plant Mimosa pudica. Sleep movements (nyctinastic movements) are controlled by the circadian clock and light signal transduction through phytochrome.
In biology, determination is the process of matching a specimen or sample of an organism to a known taxon, for example identifying a plant as belonging to a particular species. Expert taxonomists may perform this task, but structures created by taxonomists are sometimes used by non-specialists.
Within the U.S. government, security clearance levels serve as a mechanism to ascertain which individuals are authorized to access sensitive or classified information. These levels often appear in employment postings for Defense related jobs and other jobs involving substantial amounts of responsibility, such as air traffic control or nuclear ...
A UPS designed for powering DC equipment is very similar to an online UPS, except that it does not need an output inverter. Also, if the UPS's battery voltage is matched with the voltage the device needs, the device's power supply will not be needed either. Since one or more power conversion steps are eliminated, this increases efficiency and ...
