Temperature and Photosynthesis: How Does Temperature Affect the Rate of Photosynthesis in Plants?

What is the effect of temperature on photosynthesis? - …



Overall I feel that the results that I have gained do support the
hypothesis that I laid out as they clearly show that the reaction rate
of the potato catalyse increasing as temperature to an optimum point
were after the reaction rate dropped off due to denaturing.

The main variables which affect photosynthesis are light, water, CO2 concentration and temperature.

Does photosynthesis have an optimal temperature at …



The reaction rate of the Catalyse increases in a fairly straight line
between 10 degrees and 35 degrees were an optimum temperature is
reached.

I think this because light is the most important thing needed for photosynthesis.

These same older generation emitters, controller technology & drivers are the reason I did not recommend LEDs of ANY brand for "higher-end" aquarium applications until 2008 (readers of this VERY constantly evolving article in 2007 would note this too).
However NOW we have many reef/planted aquarium capable LED lights and the only thing that separates most are bells & whistles, cost, efficiency of energy input to output, colors one might desire (albeit not necessarily what the photosynthetic life is more efficient utilizing), water proofing/resistance, and warranty. Even in cost, often the other factors will override an initially low cost of many popular LED fixtures.

Photosynthesis is important because animals eat food, as it is a source of energy.

Also if the temperature is at high, then the rate of photosynthesis can not be done again.
We later realized that the older spinach plant was more efficient than the fresher one which was bizarre.

Temperature. The optimum growth temperature for D. salina is in the range of20 to 40°C (Borowitzka, LJ, 1981a) depending on the strain. Dunaliella salinacan tolerate extremely low temperatures to below freezing (Siegel et al.,1984), but temperatures greater than 40°C are usually lethal. There is alsoa strong interaction between the growth rate, temperature and salinity(Gimmler et al., 1978; Borowitzka, MA & Borowitzka, 1988a) and between lightintensity and temperature tolerance (Federov et al., 1968).

Most photosynthetic marine invertebrates should be kept with lamps of a daylight Kelvin temperature from 6400-14,000 K (higher Kelvin with deeper specimen placement, not necessarily tank depth). 20,000K daylight lamps can also be used for deeper tanks (over 22 inches) and/or supplementation with more blue lights (400nm- 490nm).

This means that the hypothesis we made before the experiment was correct; if the temperature was low, then the rate of photosynthesis would be slower and if the temperature is at its optimum point, then the rate of photosynthesis will be at its fastest.

It is also noteworthy that many "terrestrial plant lights" as well as many aquarium plant lights (often of lower in kelvin temperature) have more "red nanometer spikes" than higher kelvin 6500k, 10,000k & higher lamps.
The problem with these lights is that while all plants utilizing photosynthesis require the same essential ABCs of PAR (see the PAR section), the facts of light energy penetrating water requires higher kelvin (6500k +) be added to provide maximum PUR (see Useful light energy/PUR section). Aquatic Plants and corals have adapted/evolved to the natural light energy at certain depth of water and the misguided attempt to adapt these terrestrial plant lights is not going to be 100% effective as a light with more water penetrating blue & slightly lower red nm energy.
