Faster Rates of Photosynthesis in Spinach (Spinacia Oleracea
) Leaves as Light Intensity Surges
Abstract
Photosynthesis is a food making process that autotrophic plants use. The rate at which
photosynthesis occurs can be based off many factors such as light intensity. In this experiment
we analyzed that rate at which photosynthesis occurs by observing the time it took for Spinach
(S. Oleracea
) leaves to float to the top of a bicarbonate solution in comparison to different light
intensities. Four treatments were observed. No light, our control, low lux, medium lux and a high
lux. Results were noted and observed. Our control treatment averaged 1200+/- 0 seconds, low
lux took approximately 686.3+/- 464.76 seconds , medium lux averaged 587.7 +/- 134.90
seconds and high lux treatment took on average 432.6 +/- 267.9 seconds to notice disk flotation.
We hypothesized that as light intensity increased, the rate of photosynthesis would also increase.
If there was a lower quality of light then photosynthesis would be slower compared to higher
quality of light. Based off data, our hypothesis was supported. It can be concluded that based off
this experiment plants perform photosynthesis at a much faster rate if they have a stronger light
intensity than plants who have a low light intensity. Those who have a profession in the
agriculture business can benefit from this study as it demonstrates an adequate way to improve
the health of their crops.
