The Limiting Effect of Light Intensity on Photosynthesis

Limiting the light intensity to photosynthesis Objective: To study the limiting effect of light intensity on photosynthesis. Prediction: As the light source (electric stand) approaches the lawn (Elodea) of the pond, photosynthesis speed increases, so more oxygen is generated and bubbles are expected to increase. This means that as the light source is in the vicinity of plants, more photosynthesis takes place, as more plant surface area is exposed to light from the lamp stand, so that more oxygen is produced I will. More oxygen. foam

Influence of light intensity on the oxygen production rate of plants when photosynthesis occurs: I predict that photosynthesis will increase as the light intensity increases. Furthermore, as the light intensity increases, the photosynthetic rate increases proportionally and produces more oxygen, predicting that the oxygen level will increase. These flashlights are often used even in case of emergency or blackouts, but they are not as useful as a large flashlight because of their low light intensity. However, these flashlights are large enough to be awkward or heavy when used on the go, making them ideal for survival and outdoor use.

Influence of light intensity on photosynthesis of Elodea canadensis I want to know how much light intensity affects photosynthesis of Elodea Camadensa. I decided to do this by measuring the amount of oxygen produced during photosynthesis. Photosynthesis is the process by which all plants make food. In this process, carbon dioxide, water, and light energy are used. It produces oxygen and glucose. - Examine the influence of light wavelength on the photosynthetic rate ==== Prepare a beaker with a method of 250 cm 3 and fill with distilled water. Because distilled water is used, impurities do not destroy photosynthesis. Then take the x cm of erodia and put it in the beaker. Cover the erodia with the big end of the funnel and cover the tip of the funnel cover with a test tube. Then light up the experiment

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
