Sentences with phrase «photosynthetic activity»

"Photosynthetic activity" refers to the process by which plants and other organisms that contain chlorophyll use sunlight, carbon dioxide, and water to produce energy-rich sugars (glucose) and release oxygen. Full definition
Hence, it could be suggested that the small differences in the calcification rates observed between 100 mg / L and 200 mg / L calcium additions during the day could be a result of relatively mediocre photosynthetic activities of the endo - symbionts, but this should be further studied.
To remedy that absence, Golden's lab, along with plant physiologist Takao Kondo and colleagues at Nagoya University in Japan, developed an easy - to - read gauge of changing photosynthetic activity in colonies of the cyanobacterium Synechococcus, a blue - green alga whose one - celled organisms divide as often as once every 5 to 6 hours.

His research team envisions a series of interacting processes, or feedbacks, that maintained oxygen at very low levels principally by modulating the availability of life - sustaining nutrients in the ocean and thus oxygen - producing photosynthetic activity.
A novel nanobionic approach has been developed that imparts higher photosynthetic activity to plant leaves and extracted plant chloroplasts, the biological organelles that convert captured carbon dioxide into solar energy.
When soil dries out, plants slow down their growth, reduce photosynthetic activity, and suffer damage to their tissues.
«If trends continue, we can expect probably a doubling of primary production,» in photosynthetic activity undertaken by millions of algae, he adds.
At all of the terrestrial sites they found strong inverse correlations between satellite observed photosynthetic activity and mercury concentrations.
The seasonal fluctuations are caused by plant - based photosynthetic activity.
Because plants grow more efficiently under diffuse light conditions such as this, global photosynthetic activity could increase, pulling more of the greenhouse gas carbon dioxide out of the atmosphere.
Dr. Kiang also relates this work to research in astrobiology, particularly with regard to how photosynthetic activity produces signs of life at the global scale (e.g., biogenic gases like oxygen and photosynthetic pigments like chlorophyll) and how these may exhibit adaptations to alternative environments on extrasolar planets, resulting in other «biosignatures» that might be detected by space telescopes.
The scientists found the warm spring triggered leaf growth and photosynthetic activity earlier in the year than usual, which led to more carbon uptake than normal.
Factors affecting N fixation are growth of bacteria and / or host plants, photosynthetic activity of host plants, available mineral N and type of bacteria, Stout (1990).
«This system gives us a new insight into photosynthesis and gives us hope that we can learn from this and increase photosynthetic activity,» he said.
In a study of local ecosystem sustainability, Mohan Wali and his colleagues at Ohio State University noted that as temperature rises, photosynthetic activity in plants increases until the temperature reaches 20 degrees Celsius (68 degrees Fahrenheit).

SAN FRANCISCO, CALIFORNIA — About 1 % of the light that strikes plants is re-emitted as a faint, fluorescent glow — a measure of photosynthetic activity.
Scientists from the BOREA research unit first suspected the presence of microalgae in Paris streets after noting the characteristic green or brown color of gutter water and observing the presence of bubbles, which are the result of photosynthetic activity.
The electrical capacitance, which shows the ability of a leaf to store a charge, stayed roughly constant at a minimum value during dark periods and increased rapidly during light periods, implying that electrical capacitance was a reflection of photosynthetic activity.
The fluctuations in the CO2 curve (top) reflect seasonal changes in photosynthetic activity, which cause small differences between summer and winter concentrations of CO2.
On Tuesday, the agency moved to introduce the world to FLEX, a novel approach that could help experts assess the health of vegetation across the globe by measuring their photosynthetic activity from space.
(1) globally, photosynthetic activity (fixation of biomass) on both the land and oceans is demonstrably on the increase as a consequence of both the so - called CO2 fertilization effect AND the vastly increased anthropogenic N & P nutrient input to the continental shelves; and this in turn is
Photosynthetic activity can vary with both cloudiness and turbidity, as well as nutrient flux.
