The Effect of Light Intensity on the Rate of Oxygen Production in a Plant While relationship between the independent and dependent variable, which is. The carbon and oxygen cycle are related by complementary relationship. For example whenever animals and humans breath they breath in oxygen and breath. Study Photosyntheis: Production Of Oxygen Flashcards at ProProfs the relationship between the volatage ang the amount of oxygen dissolved in the water?.

Glucose Glucose is a simple sugar that contains six carbon atoms, 12 hydrogen atoms and six oxygen atoms.

What is the relationship between oxygen and photosynthesis?

Both plants and animals use this molecule to create energy, making it essential to life on Earth. When a plant carries out photosynthesis, it needs a source of carbon, hydrogen and oxygen to produce glucose, and it gets these elements from its surroundings. To create one molecule of glucose, the plant needs to absorb six molecules of carbon dioxide and six molecules of water.

This leaves six oxygen atoms free, which are released as waste.

  • What is the relationship between oxygen production and assimilation of carbon?

Carbon Dioxide Carbon dioxide accounts for 0. Carbon dioxide molecules, one of the building blocks of glucose, consist of one carbon atom and two oxygen atoms. Simple experiments demonstrate that limiting exposure of a plant to carbon dioxide drastically reduces its ability to carry out photosynthesis.

In contrast, increasing the plant's exposure to carbon dioxide can increase the rate of photosynthesis. Commercial greenhouses take advantage of this fact by increasing the availability of carbon dioxide to speed up the growth of plants. OR, count the number of bubbles.

Photosyntheis: Production Of Oxygen

Repeat twice and obtain an average of the results. Repeat steps 4 and 5, with increasing distances away from the light source e. Note that doubling the the distance does not half the intensity, rather quarters it. This indicates that the rate of photosynthesis increases with light intensity. However, at sufficiently high levels of light intensity, the rate oxygen evolution remains constant.

Use the Waterweed Simulato r to manipulate the light intensity, wavelength and carbon dioxide and see their effect on the rate of photosynthesis.

Why is sodium hydrogen carbonate solution used instead of water? Sodium hydrogencarbonate increases carbon dioxide availability, and ensures that carbon dioxide is not a limiting factor for the the reaction. Plain water water may not contain enough oxygen so that the maximum rate of photosynthesis can occur.

Tap water may be used to make the solution, but only after it has been left to stand overnight, so that it chlorine content is reduced. Chlorine tends to inhibit the rate of photosynthesis. Detergent may be added to reduce surface tension. This will allow bubbles to escape freely. When surface tension is high, bubbles are of varied sizes. The power of the lamp may be varied e. Why was the laboratory darkened?

When counting bubbles, the bubbles may be of varied sizes, leading to inaccurate conclusions about the rate of oxygen production. If the rate of bubbling is very high, then there may be errors in counting.

Another source of inaccuracy is the presence of other light sources, of which intensities may be varied by shifting shadows. How can we prove that oxygen was the gas produced? A glowing splint should be placed near the mouth of the test tube, where the gas was collected.
