The Effect of Light Intensity on the Rate of Photosynthesis

Influence of light intensity on photosynthetic rate Objective: To study the influence of light intensity on photosynthetic rate. Theory: Before predicting what will happen, you have to see how photosynthesis occurs. Photosynthesis is the way plants make food for themselves. For photosynthesis, carbon dioxide, water, light is necessary. Leaves of plants called chlorophyll have green substances.

Influence of light intensity on the photosynthetic rate of aquatic plants Introduction The input variable I consider is light. Because light is only one of the four elements necessary for the photosynthesis of green plants. Photosynthesis is the process by which green plants produce their own food using sunlight, carbon dioxide, water, chlorophyll. This process is also influenced by the temperature around the plant (we test plant species, weeds in the pond, photosynthesis is best around 20 degrees Celsius).

My goal is to investigate the effect of light intensity on the photosynthetic rate. To do this, you need to adjust the amount of water, carbon dioxide, and light. In addition, the distance of the light must be controlled by control and different levels of oxygen should escape into the plant. Soak plants in water so that oxygen can be easily measured. Oxygen is measured by the amount of foam produced by the plant for a period of time. In this experiment, we predict that the farther the light from the leaves is, the less air bubbles will be. I only got this answer because photosynthesis only occurs under light and reacts faster under warm conditions.

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
