Light intensity levels can have a significant effect on photosynthesis rates, which are directly related to a plant’s ability to grow. Effect of light intensity on photosynthesis. Why is this?

Plant Growth Plant growth processes involve the use of light, carbon dioxide and water to manufacture food for the plant’s use, according to the Texas A&M University Agricultural Extension Service. The purpose of experimentation was to determine if light intensity had any effect on the rate of photosynthesis as tested through absorbance values, to determine which wavelength of light was most effective for photosynthesis, and to determine which pigments contributed most to each peak of the action spectrum and how the absorption spectrum correlated to the action spectrum. Plants need light energy to make the chemical energy needed to create carbohydrates. The rate of photosynthesis is directly proportional to light intensity (Kent, 2000).

Therefore light is actually one of the essential factors in the process of photosynthesis. Effect of a Varying Light Intensity on Rate of Photosynthesis-Updated - Duration: 4:05.

At low light intensities above the light compensation point (LCP), photosynthetic rate increases proportionally to the light intensity and reaches a …

The effects of changes in light intensity on the rate of electron transport from photosystem II to artificial electron acceptor 2,6-Dichlorophenolindophenol in the light reactions of photosynthesis in Spinacia oleracea L. Maddie Gibson Group members: Addison Ely, Brooke Koebele, Elise Ziegenhorn BIOL 240 Dr. Loni Walker December 15, 2016 Plant Growth Plant growth processes involve the use of light, carbon dioxide and water to manufacture food for the plant’s use, according to the Texas A&M University Agricultural Extension Service.

Green plant cells that are placed in the dark will not photosynthesis.

Use Cabomba or Elodea, which are sold in aquarium shops.
The effect is that the higher the light intensity the increase in the amount of bubbles produced, this bubble produced from the plant is oxygen.

The effect of light intensity on photosynthesis can be investigated in water plants. Too high or too low PAR intensities adversely affect the photosynthetic machinery. The effect of light intensity on photosynthesis can be investigated in water plants. Investigating photosynthesis. 1099 words (4 pages) Essay in Biology. The effect of light intensity on the rate of photosynthesis At section B the line is becoming constant.

This is because light plays a major role in photosynthesis, it helps the leaf to give out oxygen and take in carbon dioxide from the atmosphere which is polluting our world.

Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide. 21/04/17 Biology Reference this Disclaimer: This work has been submitted by a student. Use Cabomba or Elodea, which are sold in aquarium shops. This in turn increases the rate of photosynthesis. Increasing the light intensity will boost the speed of photosynthesis. Light is one of the external factors that affect the rate of photosynthesis.

The light intensity range for most plants falls between 1,200 and 2,000 lumens (measurement of light intensity). After point x another factor might be affecting the rate of photosynthesis, which is known as a ‘limiting factor’. The secondary data above backs-up my prediction because it shows that, as the intensity of light increases, so does the rate of photosynthesis until point x. The potted trees were exposed to drought stress for 12 days and different light conditions (100, 60 and 25% sunlight). #41 Effect of Light intensity on the rate of Photosynthesis. Investigating photosynthesis. Experiment .
