The term phytoplankton encompasses all photoautotrophic microorganisms in aquatic food webs.
2.
Its ability for photoautotrophic growth under extreme conditions, and it is distinguished by its characteristic sulfur metabolism.
3.
For example, purple sulfur bacteria and cyanobacteria are generally photoautotrophic whereas purple non-sulfur bacteria are photoorganotrophic.
4.
Thus, the total photoautotrophic primary production for the Earth is about 104.9 billion tonnes C / yr.
5.
They also provide shade and, although frequently confused with them, can reduce certain light-generated growths of photoautotrophic algae.
6.
"Chloroflexus aurantiacus " is thought to grow photoheterotrophically in nature, but it has the capability of fixing inorganic carbon through photoautotrophic growth.
7.
Moss is a very frugal photoautotrophic organism that has been kept " in vitro " for research purposes since the beginning of the 20th century.
8.
Photoautotrophic organisms, such as algae and vascular plants, can exhibit a very wide range of physiological plasticity in elemental composition and thus have relatively weak stoichiometric homeostasis.
9.
They can switch between a photoautotrophic and photoheterotrophic metabolism depending on the environmental conditions that maximize their growth, employing the pathways that use the least amount of energy.
10.
Photoautotrophic tissue culture is defined as " micropropagation without sugar in the culture medium, in which the growth or accumulation of carbohydrates of cultures is dependent fully upon photosynthesis and inorganic nutrient uptake ".
