The Effect of Light Intensity on the Rate of Photosynthesis

Effect of light intensity on experimental photosynthetic rate: The effect of light intensity on photosynthetic rate was experimentally investigated. Purpose: To investigate whether light intensity affects photosynthesis speed. Introduction: Photosynthesis is the process of providing "food" to plants, this "food" is called glucose. This process is done on the leaves of the green plant that is the use of leaves. Plants need to do four things before doing photosynthesis They are light, chlorophyll, carbon dioxide and water.

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

It is a plant. For example, when examining how the light intensity affects the photosynthesis speed, you can create a "photosynthetic photoresponse curve" - ​​photosynthetic rate at different light intensities. The shape of the curve varies depending on plants and plants with different lighting environments. "Optical response curve" itself is a form of measurement. How do you think about the light response curve of leaves growing in the shade (the first variable) compared to the leaves growing under the sun? In this case, the sun and shadow are the second variables. Comparative photoresponse curve is a standard research technique of plant physiology and ecology
