The Relationship Between Light Intensity and the Rate of Photosynthesis

The relationship between light intensity and photosynthetic rate is studied by the relationship between light intensity and photosynthetic rate. Because animals eat food, photosynthesis is important. Food is an energy source. All creatures need to constantly supply energy to grow, regenerate, move. Plants do not eat food, but their leaves contain some starch. The symbolic equation for photosynthesis is 6 CO 2 + 6 H 2 O - light C 6 H 12 0 6 +6 02.

Influence of light intensity and temperature on photosynthesis rate The purpose of my experiment was to judge whether light intensity and temperature affect photosynthetic rate of plants. To do this, place the pond with varying light intensity and temperature and observe the amount of oxygen released. I am using Ikeba. Because it has a rare chunk that emits air bubbles from the cutting edge when placed in water. - Influence of light on photosynthesis Plants need the same food lighting as animals, but when animals have to eat something else to get food, the plants make themselves. The way they do this is called photosynthesis. Other ways in which plants, such as leaves and roots, green, are different from animals are related to photosynthesis.

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

Photosynthesis is the process by which plant cells convert carbon dioxide (CO 2) into food sugar by light energy. The purpose of this experiment was to determine whether different light intensities had different effects on the photosynthesis of the two plants. One plant grows under normal light conditions and the other grows under shadow conditions. Each plant was placed in a sealed plastic box and allowed to acclimate. Using a vernier CO 2 electrode, the CO 2 concentration was measured at 1 hour intervals per minute over 5 minutes. This process is repeated for different light intensities measured using a light sensor. Overall, the rate of change in CO2 concentration in both plants has decreased. Under specific light intensity, the rate of change in carbon dioxide concentration becomes negative (about 45 arbitrary units for shade plants and about 80 arbitrary units for light plants)
