1a. The results from Figure 1 illustrate that the control treatment of the Tomato plant, has a maximum quantum yield of Photosystem II than chilled plants. It appears that over time, the average Fv/Fm seems to be constant with no drastic changes in the levels, with values staying between the ranges of 0.7 to 0.8 Fv/Fm. On the other hand, the chilled treatment of Tomato plants begins at 0.2257 Fv/Fm at time = 0 minutes, and the last plant has a Fv/Fm value of 0.6526 when time is at 150 minutes. It appears that the chilled plant does not surpass its maximum quantum yield value of photosystem II than control plants.

The results shown in Figure 2 express how controlled plants have a higher quantum yield average than chilled plants from the beginning of the experiment and towards the end. The control treatment exhibited a decrease in the amount light absorbed by photosystem II used in photochemistry over between 0 minutes to 50 minutes, with values of 0.271 and 0.211 respectively. After 50 minutes, the control treatment had a significant increase of the amount of light absorbed in photosystem II, where average values increased to 0.293. From that point up to 150 minutes, there was a slight decrease of light absorbed. When looking at the curve of the chilled plants, it appears that it is a symmetry of the control values; the average light absorption occurs at 0.121 and increases to 0.192 at the 50-minute mark. From then on, the chilled treatment remains slightly constant with small fluctuations of the average light absorbed in photosystem II used in …show more content…
Studies on the concentrated tomato plant (Lycopersicon esculentum) measured at 25˚C (around room temperature), caused photosynthesis to be inhibited up to 60% when they were chilled in the dark for 16 hours (Kee et al., 1986). This inhibition exhibited that there was a reduced stomatal conductance when looking at the rate of light-saturated photosynthesis and CO2 concentrations (Kee et al., 1986). Another factor of the inhibition of photosynthesis in Tomato plants can be due to biochemical malfunctions occurring in the chloroplast where is takes place. The dark chilling of the plant is directly correlated to decreased chloroplast activity and smaller stomatal conductance (Kee et al.,
