Photosynthesis Lab Report

The results from Table 2 and Figure 1 reveal that the rate of photosynthesis increased from a cold temperature to room temperature; however, the rate of photosynthesis decreased in the body temperature. This means that the hypothesis was rejected. The rate of photosynthesis did increase, but only to a certain point. Based on these results, it can be concluded that photosynthesis performs better at room temperature that at cold temperature because thee low temperature slows down the reactions taking place in the chloroplasts. Photosynthesis performs better at room temperature than at body temperature because at hot temperatures, the reactions in photosynthesis must be negatively affected. It is possible that this hot temperature could have denatured
The room temperature tube not placed in a bath acted as the control due to the fact that it represented normal conditions with no constant bath temperature around. An interesting observation made from Figure 1 and Table 2 was that the room temperature tubes hade relatively different rates of photosynthesis even though they were at the same temperature. This could show that temperature is not the only determining factor is the rate of photosynthesis. An explanation for an the room temperature tube in the bath having a rate of 1.86 %T/min as opposed to the .75%T/min of the room temperature tube without a bath is that there may have been more water in the air around the bath, so the chloroplasts were able to absorb more water while in the tube to speed up the rate. The chloroplasts within the tube not in a bath may not have had access to as much water in the air, thus causing a lower rate of photosynthesis. Table 2 also shows that a larger difference in transmittance from 0 minutes to 15 minutes, yielded a larger rate of photosynthesis. A faster rate of photosynthesis also forced transmittance to increase as the solution became
