Increasing the light intensity increases photosynthesis speed. Purpose: To see if photosynthesis speed increases with increasing intensity of light. Prediction: We predict that photosynthesis speed will increase as light intensity is increased. I think that light is the most important thing necessary for photosynthesis. Then I think that the speed of photosynthesis will remain the same when it reaches a certain point. This is because the plant runs out of all carbon dioxide (sodium bicarbonate) and can obtain the light required by the plant. However, without carbon dioxide, photosynthesis will not be possible.

For example, light intensity affects photosynthesis speed. Without light there is no photosynthesis. As the light intensity increases, the speed of photosynthesis increases as long as other factors are available. As interest rates rise, eventually there will be another factor shortage. The figure below shows the effect of low carbon dioxide concentration. After all, it is insufficient to support a higher photosynthetic speed, and raising the light intensity has no effect, so the speed is smooth.

As the intensity of the light increases, the rate of the light dependent reaction increases proportionally to normal photosynthesis. However, as the light intensity increases, the photosynthetic rate is ultimately limited by several other factors. Chlorophyll a is used in two optical systems. The wavelength of light is also important. PSI absorbs energy most efficiently at 700 nm and absorbs PSII at 680 nm. A high proportion of energy concentrated on these wavelengths produces a high photosynthetic rate

During photosynthesis, as the speed of photosynthesis increases, the intensity of light increases. (Pang 2006) In my results, the distance of light intensity increases as photosynthesis decreases. In other words, as the light intensity decreases, the photosynthesis rate also decreases. In this case, my results are true. There are some experimental errors in this experiment. Since there is other light from the lighting adjacent to the room, it is difficult to ensure that the chloroplastic solution does not function until it is placed under the lamp. Therefore, in order to reduce the influence of light the experiment needs to be done in a dark room, the result will be more accurate. At the same time, we need to prepare more cuvettes. There are things in the cuvette that affect the results if there is something that is not clean.
