Developmental biology is the study of the process by which animals and plants grow and develop. Developmental biology also encompasses the biology of regeneration, asexual reproduction, metamorphosis, and the growth and differentiation of stem cells in the adult organism.
A plant adapted to growing in crevices or hollows, such as in cliff faces. Compare cremnophyte. [28] [29] chimera An individual composed of two or more genetically distinct tissues, most commonly as a result of a graft and sometimes by mutations that occur during cell division or cellular transfers during seed development. chiropterophilous
Plant embryonic development, also plant embryogenesis, is a process that occurs after the fertilization of an ovule to produce a fully developed plant embryo. This is a pertinent stage in the plant life cycle that is followed by dormancy and germination . [ 1 ]
The development of a zygote into a multicellular embryo proceeds through a series of recognizable stages, often divided into cleavage, blastula, gastrulation, and organogenesis. [ 6 ] Cleavage is the period of rapid mitotic cell divisions that occur after fertilization.
The abstract term physis is derived from the verb phyesthai/phynai, which means “to grow”, “to develop”, “to become” (Frisk 2006: 1052; Caspers 2010b: 1068). In ancient philosophy one also finds the noun "physis" referring to the growth expressed in the verb phyesthai/phynai and to the origin of development (Plato, Menexenos 237a ...
In addition to growth by cell division, a plant may grow through cell elongation. This occurs when individual cells or groups of cells grow longer. Not all plant cells grow to the same length. When cells on one side of a stem grow longer and faster than cells on the other side, the stem bends to the side of the slower growing cells as a result.
(pl.) aboiteaux A sluice or conduit built beneath a coastal dike, with a hinged gate or a one-way valve that closes during high tide, preventing salt water from flowing into the sluice and flooding the land behind the dike, but remains open during low tide, allowing fresh water precipitation and irrigation runoff to drain from the land into the sea; or a method of land reclamation which relies ...
Personal development or self-improvement consists of activities that develops a person's capabilities and potential, enhance quality of life, and facilitate the realization of dreams and aspirations. [1] Personal development may take place over the course of an individual's entire lifespan and is not limited to one stage of a person's life.
