Document Summary
Frost damage, heat damage, salt; road runoff & irrigation, evaporation/drought: cold stressor research: glycine betaine is a molecule that moderates stresses in plants. Exposed two groups of plants to the cold for 7 days, and then took them in to examine. It increased the resistance to cold stressors in tomato plants. The organic molecules are used by the photosynthetic organisms themselves as fuels. Also form the primary energy source for animals, fungi, and other heterotrophs (consumers and decomposers: photosynthesis can be divided into the light reactions and the calvin cycle. In eukaryotes, both stages take place in the chloroplasts: the light reactions use the energy of the light to drive the synthesis of nadph and. Occurs in the thylakoid membrane: calvin cycle fixes co2 into carbohydrates. Reduction reaction with electrons (and protons) being added to co2. Common reaction: co2 + h+ + e- (ch2o)n. In most photosynthetic organisms the source of electrons required for fixation is water; oxygenic photosynthesis.
