  • Two or more taxa once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), but this is not a species complex. (wikipedia.org)
  • organisms
  • Natural philosophy and natural theology encompassed the conceptual and metaphysical basis of plant and animal life, dealing with problems of why organisms exist and behave the way they do, though these subjects also included what is now geology, physics, chemistry, and astronomy. (wikipedia.org)
  • term
  • The term "autoinduction" was first coined in 1970, when it was observed that the bioluminescent marine bacterium Vibrio fischeri produced a luminescent enzyme (luciferase) only when cultures had reached a threshold population density. (wikipedia.org)
  • minimal
  • A plant only reacts to gravity if the gravistimulation is maintained for longer than a critical amount of time, called the minimal presentation time (MPT). (wikipedia.org)
  • natural
  • It is all too easy for a scientist, believing he has achieved a new way of understanding some natural phenomenon, to promote his idea for some management purpose. (fws.gov)
  • components
  • This phenomenon was termed "autoinduction" because it involved a molecule (autoinducer) that accumulated in a growth medium and induced the synthesis of components of the luminescence system. (wikipedia.org)
  • time
  • Thus in a year's time it would take millions of plants weighing tons to feed the several steer weighing a few tons that could support one or two people. (thefreedictionary.com)
  • allows
  • Quorum sensing is a phenomenon that allows both Gram-negative and Gram-positive bacteria to sense one another and to regulate a wide variety of physiological activities. (wikipedia.org)
  • This phenomenon allows them to act as an antifreeze at concentrations 1/300th to 1/500th of those of other dissolved solutes. (wikipedia.org)
  • Activity
  • In addition to lipid extracts with JH activity, a phenomenon found in various human organs, microorganisms and plants, JH-mimetic materials were found in American paper products in 1964. (brillonline.com)
  • systems
  • The optimal rotational speed has been investigated by comparison to 'true' responses to microgravity as seen in space-grown plants, and determined to be between 0.3 and 3 rpm for most plant systems. (wikipedia.org)
  • production
  • this may cause an increase in ethylene production, which may in turn cause some of the phenomena otherwise attributed to agravitropism. (wikipedia.org)
  • cell wall
  • Lignin is an integral cell wall component of all vascular plants. (plantphysiol.org)
  • Lignin is a polymeric constituent of the plant cell wall and, second to cellulose, is the most abundant organic compound in the biosphere. (plantphysiol.org)
  • The plant cell wall was easily visible even with these early microscopes but no similar barrier was visible on animal cells, though it stood to reason that one must exist. (wikipedia.org)
  • experiences
  • The slow rotation means that the plant experiences a gravitational pull that is averaged over 360 degrees, thus approximating a weightless environment. (wikipedia.org)
  • water
  • Each ecosystem consists of a community of plants and animals in an environment that supplies them with raw materials for life, i.e., chemical elements and water. (thefreedictionary.com)
  • The water in plant and animal wastes and dead tissue then evaporates and can be recycled. (thefreedictionary.com)
  • The phenomenon has been studied in some detail in frogs which, although not hibernators in the true sense, can endure very low water temperatures under the conditions of profound hypoxia that exist when they lie dormant for long periods below the surface. (nottingham.ac.uk)
  • early
  • The early successful purification of aequorin led to the first experiments involving the injection of the protein into the tissues of living animals to visualize the physiological release of calcium in the muscle fibers of a barnacle. (wikipedia.org)
  • communities
  • 2002). Additionally, gene expression, intracellular signaling, and hormone response may also affect the power of self-thinning in plant communities indirectly. (sinica.edu.tw)
