There's a lot of attention being given to what happens when the plankton production («primary production» — the first step
where photosynthesis occurs).
The life on Earth needs four elements, which are: «the green photons (i.e. photons from the visible part of the electromagnetic radiation)», H2O, CO2 and the heat amount keeping temperature of the system within the temperature range
where the photosynthesis can take place.
On comments there was a question about the temperature

Can you guess which part is represents the chorplasts (the organelle
where photosynthesis occurs)?
Quantum physics governs the universe on incredibly small scales — including at the level of molecules inside chloroplasts, the structures inside plants

The findings will help scientists disentangle inputs and outputs in places like the Amazon rainforest,

photosynthesis.
The fungi coexists on the plant's roots

photosynthesis.
Mycorrhizal fungi live in the roots of host plants,
where they exchange sugars that plants produce by
photosynthesis for mineral nutrients that fungi absorb from the soil.
For this reason methanol fuel cells will be used,

photosynthesis,
where they move electrons in order to create the energy molecules.
Carotenoids are common in algae and some bacteria and fungi,

photosynthesis.
Exciton diffusion is also a basic mechanism underlying
photosynthesis: Plants absorb energy from photons, and this energy is transferred by excitons to areas
where it can be stored in chemical form for later use in supporting the plant's metabolism.
Mycoheterotrophy is a term derived from Greek to describe the bizarre symbiotic relationship between some plants and fungi,
where the plant gets nutrients parasitizing upon fungi, rather than using
photosynthesis.
M.I.T.'s Angela Belcher took her cue from plants,
where special pigments capture solar energy in
photosynthesis, involving the splitting of water.
In places
where the ground is bare — from overgrazing or from the common practice of leaving fields unplanted for part of the year —
photosynthesis stops, and so does the storage of carbon in the soil.
Only when we know when and
where certain nutrients are available for plankton growth we can also estimate how much carbon the plankton can bind by
photosynthesis and thus remove from the atmosphere.»
The thylakoid is
where the light - dependent reactions in
photosynthesis occur, yet the exact nature of those reactions have, paradoxically, been in the dark for scientists.
But corals, only capable of living in the upper photic zone of the sea (
where enough light is present for
photosynthesis), kept on building their reefs higher and higher, managing to always keep the top layer of the coral reef close to the sea surface.
Some organisms can take opportunistic advantage of a similar process,
where they engulf an alga and use the products of its
photosynthesis, but once the prey item dies (or is lost) the host returns to a free living state.
«When the ice goes away, more sunlight can get in, allowing the gradual development of new ecosystems
where little
photosynthesis occurred previously.
They need the sun's energy to carry out
photosynthesis, but too much light damages the chloroplasts in plant cells
where light, water, and carbon dioxide are converted into sugar and oxygen.
Where Quantum Physics Meets
Photosynthesis Recent experimental results suggest that quantum - mechanical coherence plays a role in efficient energy transfer in photoactive complexes.
I was awarded my PhD from James Cook University in 2001
where my research project focussed on
photosynthesis and bleaching in the symbiotic giant clam Tridacna gigas.
But just to simplify, it is in these fireworks inside the mitochondria,
where the oxygen we breathe may get a hold of an electron we ate that was pumped with energy by plants (thanks to
photosynthesis), and transform that oxygen molecule into what's called superoxide, which can damage our delicate cellular machinery — oxidize our cellular machinery.

Where Does
Photosynthesis Occur?
Dominance of 3 carbon
photosynthesis was seen in ruderal through stress tolerant - ruderal to competitive - ruderal environments
where water is the key part of the water - energy dynamic in effect.
On the CO2 as pollutant vs fertilizer discussion, roughly half of the
photosynthesis on earth occurs in the oceans
where CO2 is not a limiting factor.
(apparently the southern hemisphere CO2 air concentration actually follows the northern one by dropping several ppm in Nov - Apr (southern summer), rather than the seasonally imposed one in the north
where it drops ~ 5ppm in the winter due to no
photosynthesis.)
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.
Compared to forests, croplands are less efficient in transpiration, a daytime process
where water evaporates from leaves during
photosynthesis and cools the air.
We've seen technologies
where the electrons in the soil near plants» roots was are used to power a fuel cell and concepts for moss - powered lamps, but this discovery from University of Georgia researchers taps
photosynthesis directly for producing electricity.
is lost through the stomata
where carbon dioxide enters If its hot the plants will close the stomata to keep from loosing water but
photosynthesis will slow down due to the lack of carbon dioxide Some plants that live in dry areas have special ways to save water and carry out
photosynthesis C4 Plants Have a special chemical pathway that gets carbon dioxide into the Calvin /
There are a lot of hypothetical deliberations on
where this «missing» CO2 is going: into increased terrestrial plant
photosynthesis or soil absorption, dissolved into the ocean,
where it is buffered chemically or converted by
photosynthesis from phytoplankton, entering the food chain and possibly getting converted to carbonates that eventually end up on the ocean floor, into limestone through weathering or dissipated into space, etc..
«This very fast turnover, along with the fact that phytoplankton are limited to just a thin veneer of the ocean surface
where there is enough sunlight to sustain
photosynthesis, makes them very responsive to changes in climate,» Behrenfeld said.
And as to his claim that there may be «places around the world
where global warming will lead to less crop success and yield, even when taking into account the carbon dioxide fertilization effect,» he appears to be equally ignorant that rising levels of atmospheric CO2 tend to raise the temperature of optimum plant
photosynthesis beyond the predicted temperature values associated with global warming, effectively nullifying this worn out claim (Idso & Idso, 2011).
If visible light wasn't transmitted through unchanged we would have no life in the ocean,
where it began by
photosynthesis.
For example, as energy is conserved in
photosynthesis where visible light converts to chemical energy, sugars, and not to heat energy.
Work in the Scale - Up and Prototyping program informs the JCAP scientific efforts as to

But of course, when it's pointed out that not all absorption of electromagnetic radiation creates heat, for example in
photosynthesis when it converts to chemical energy and not heat energy and in the atmosphere
where absorption of visible light by the electrons of the molecules of nitrogen and oxygen which spit out the same non-thermal energy that went in, this is ignored.
As in the empirically tried and tested proven use of such in greenhouses
where they want to maximise visible light to enhance
photosynthesis and don't want to cook the plants..
Here's Merriam Webster's version: Main Entry: carbon dioxide Function: noun: a heavy colorless gas CO 2 that does not support combustion, dissolves in water to form carbonic acid, is formed especially in animal respiration and in the decay or combustion of animal and vegetable matter, is absorbed from the air by plants in
photosynthesis, and is used in the carbonation of beverages I know you'll all correct me if i'm wrong in stating if CO2 has no scientific facts supporting global warming based upon a factor of greenhouse gases (as opposed to solar radiation in another post, which would be defined by variations in earth, space, or similar factors), then
where does science determine that CO2 «disolves in water to form carbonic acid» and is «absorbed from the air by plants in photosythesis»?
«We have to learn as much as we can from
photosynthesis, in other words what goes on in leafy plants, because that's
where most of our energy has otherwise come from in terms of fossil fuels or current kinds of carbon materials that we use either as food or fuel,» MacFarlane said.
