Quantum physics governs the universe on incredibly small scales — including at the level of molecules inside chloroplasts, the structures inside plants where
photosynthesis happens.
Photosynthesis happens in the «palisade» cells in the leaf: Palisade cells Close up on a palisade cell: Cell wall Cell membrane Nucleus Large vacuole Cytoplasm Chloroplasts (containing chlorophyll) How do Plant Roots Work?
Not exact matches
We are using visible light to accomplish this, so in reality we are converting light energy into a chemical output, similar to what
happens in
photosynthesis.
For example, in a recent Nature Physics paper, physicist Neill Lambert of the Advanced Science Institute in Japan called out new
photosynthesis research as remarkable just for suggesting quantum effects can
happen in biological systems at room temperature.
These changes
happened even as the concentration of phytoplankton fell, along with levels of chlorophyll - a, the pigment essential to
photosynthesis.
Yu and his colleagues aren't certain how this is
happening, but the mutation that enabled ethylene production has also stimulated
photosynthesis.
«Knowing how this
happens is important for understanding the design principles used in natural
photosynthesis,» Yachandra says.
Living Sunlight talks to young children about
photosynthesis (a vital process that most adults would be hard put to explain) in a way that tells what is actually
happening at the molecular level.
If you're taking current
photosynthesis, then there's many ways to do cellulosic processing, none of which should have gotten into the large - scale mainstream, but there's a lot of promise that that might
happen.
But before he leaves I tell him that he should not forget what's
happening to the oceans, where the other major user of carbon for
photosynthesis live — the phytoplankton.
In this case wood may be laid down only on whichever side of the tree has sustained the least defoliation, as
photosynthesis might only
happen there.
So it is quite likely that plant
photosynthesis (including that
happening in the ocean from phytoplankton) could well be constrained by CO2 concentration at 280 ppmv, with a slightly higher input from animal respiration plus emissions from the Earth's interior balancing out the natural decay rate.
During the day, although there is more uptake through
photosynthesis, more turbulence
happens either by increased wind speed or by increased soil heating by the sun or both.
While it takes anywhere from months to decades for plants to sequester carbon through
photosynthesis, combustion and release of carbon's combustion product, carbon dioxide,
happens in seconds.
The climate catastrophists attempt to create fear by mentioning the carbon cycle but just
happen to omit that significant oxygenation of the atmosphere took place when the planet was in middle age and this process of
photosynthesis resulted the recycling and sequestration of carbon.
The first equation summarizes
photosynthesis and basically shows us what
happens on land.
In fact, if that did not
happen,
photosynthesis would use up atmospheric CO2 in about 2.5 million years (leaving aside the anthropogenic component) and the planet would go dead.
This
happens because biofuels — fuels derived from recent
photosynthesis — are basically carbon neutral because all carbon released by burning has recently been taken from the atmosphere.
«As best scientists can tell, this is what
happens: Rising CO2 revs up
photosynthesis, the process that helps plants transform sunlight to food.
What
happens for example to the symbiotic algae that live within the coral's tissues if the turbidity caused by a reflective hydrosol should impede sufficient light reaching the algae and therefore affecting
photosynthesis?
There's a lot of attention being given to what
happens when the plankton production («primary production» — the first step where
photosynthesis occurs).
The explanation for why autumn leaves put on such a display has to do with cooling weather and a drop in the chlorophyll that usually hides the other pigments of a leaf; the vivid colors were there all along, but green rules the roost as long as
photosynthesis is
happening.
