More light can mean more photosynthesis. Light water and carbon dioxide.
Please mark me as the brainliest.
How does light intensity affect oxygen production. Support for our alternate hypothesis which states that light intensity has an effect on O 2 production in C. We predicted that we would see an increase in O 2 production with an increase in light intensity since light is required to fuel the photosynthesis process. This seems to be the overall result since we observed an increase in O 2.
We put 5 grams of elodea leaf in each three test tubes we were given We filled the test tubes to the top with water and added 2 grams of Baking Soda We covered one test tube in foil so that light couldnt get into it this was our control We measured each at 1 minute three minutes five minutes ten minutes and fifteen minutes. Light Intensity Experimental Question. How Does Light Intensity Affect Oxygen Production.
Set The Fish Number To 0 And The Plant Number To 5. Leave The Other Variables At The Default Values 25 Degrees White Light. Set The Light Intensity To 100 4.
Record The Starting And Ending Oxygen Values. Biology Assignment Help Photosynthesis Lab How does light intensity affect oxygen production. Oxygen production depends on photosyntheis which in turn depends on light intensity.
Hope it helps. Please mark me as the brainliest. Oxygen is a waste product.
More light can mean more photosynthesis. It doesnt necessarily mean more though. When we think of photosynthesis as a process we can see that there are at least three things that can limit the process.
Light water and carbon dioxide. More light wont help if we dont have enough water and carbon dioxide. How does light intensity affect oxygen production.
The greater the light intensity is the oxygen production is also greater. The oxygen production begins to decrease at a light intensity of 37. Move the Light intensity slider back and forth.
How does light intensity affect oxygen production. Up to 40 increasing the light intensity increases the oxygen production. Light intensity directly affects the light-dependent reaction in photosynthesis and indirectly affects the light-independent reaction.
Light is a limiting factor when the light intensity is too low to allow the light-dependent reaction to proceed at its maximum rate. How does CO2 level affect oxygen production. Increasing CO2 production increases oxygen production.
Greater flow of oxygen corresponds to a higher rate of photosynthesis. Why would it be hard to find the ideal light intensity if the temperature were very hot or cold. The fact that no gas was produced while the setup was kept in the dark showed that light was the cause of the production of oxygen.
The increases in bubbling gas production as the light source is moved closer to the plants indicate that the rate of oxygen production by the photosynthesis is affected by the intensity of the light source. I predict that as the intensity of light is increased so would the photosynthesis. Furthermore I predict that if the light intensity increases the rate of photosynthesis will increase at a proportional rate and more oxygen will be produced and therefore the oxygen levels will increase.
However the lower the light intensity. Light intensity a slight trend suggested light intensity did have an effect on the rate of photosynthesis. The effect of light intensity followed a Michealis-Menten curve where increases in light intensity corresponded to increases in oxygen production until a peak in oxygen production occurred at a light intensity of 6000 lux.
Green plants and algae use light energy to make glucose and oxygen from carbon dioxide and water. Temperature carbon dioxide concentration and light intensity can affect the rate of photosynthesis. 2 Inhibition of photosynthesis CO 2 fixation and growth if seen increases with increasing oxygen concentration and with increasing light intensity at light intensities greater than saturation.
3 The inhibition of net photosynthesis observed cannot be attributed to high light intensity alone. How does light intensity affect oxygen production. Light intensity affects oxygen production because when there isnt enough light little no oxygen is being produced when there is a lot of light more oxygen is being produced.
Experiment with the vertical Temperature slider upper left and the CO2 level slider. In our chosen prac we attempted to investigate the response of dissolved oxygen concentrations in water when a culture of Chlorella is either exposed to bright light or to low light. Chlorella a single celled green algae like all photoautotrophs.
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. 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.
