How hould you demonstrate that elodea carries out photosynthesis at a faster rate than it carries out respiration?
Do a pH test. The more CO2 consumed (photosynthesizing) the higher the pH. The more CO2 produced (Respiring) the lower the pH. And if a plant is photosynthesizing and respiring at the same rate, the pH will remain level. During a lab like this, we used bromothymol blue to test the pH levels. It will turn yellow if pH <7, blue if pH >7, and Green as the solution changes from acid to base or base to acid.
What else can I help you with?
Does elodea conduct photosynthesis in light and dark?
Elodea can conduct photosynthesis in the light, utilizing light energy to convert carbon dioxide and water into glucose. In the dark, elodea will not photosynthesize, but will perform cellular respiration, breaking down stored sugars to produce energy.
What happened when you placed Elodea at the light compensation point?
When Elodea is at the light compensation point, the rate of photosynthesis matches the rate of respiration. This means that the amount of oxygen being produced through photosynthesis is equal to the amount being consumed through respiration, resulting in no net change in oxygen levels in the water.
What molecule was produced by the elodea while it was exposed to light?
Oxygen was produced by the elodea during photosynthesis while it was exposed to light.
What does elodea use to power its cellular process?
Elodea primarily uses sunlight as its energy source to power cellular processes through photosynthesis. It converts sunlight, water, and carbon dioxide into glucose and oxygen, which fuels its growth and metabolism.
Why was NaHCO3 used in the tube with the Elodea?
NaHCO3 or sodium bicarbonate is used in a tube with Elodea and water so the student can count how many bubbles are produce. This is to mimic photosynthesis and oxygen turning into gas adding sodium bicarbonate powder to the water increases the amount of carbon dioxide in the water.

Why is Elodea placed in both flasks?
Elodea is placed in both flasks to show how aquatic plants release oxygen during photosynthesis. By comparing the presence of bubbles in the light and absence of bubbles in the dark, one can observe the effect of light on the process of photosynthesis in Elodea.
What molecule was produced by the elodea while it was exposed to light?
Oxygen was produced by the elodea during photosynthesis while it was exposed to light.
Do onions have choroplasts do elodea plants carry out photosynthesis?
Just did this lab in Biology. Onion cells do not have chloroplasts; therefore, they do not possess the green pigment, chlorophyll, that chloroplasts produce. Elodea plants do carry out photosynthesis.
What does elodea use to power its cellular process?
Elodea primarily uses sunlight as its energy source to power cellular processes through photosynthesis. It converts sunlight, water, and carbon dioxide into glucose and oxygen, which fuels its growth and metabolism.
Which has a higher rate of respiration Elodea or a small fresh water zebra fish?
The zebra fish will have a higher respiration rate
What kind of food does elodea eat?
it makes its own food through photosynthesis it makes its own food through photosynthesis
Does elodea respire in the dark or the light?
Elodea respires in both the light and the dark. However, the rate of repiration exceeds the rate of photosynthesis when the plants are kept in the dark.
What would happen if Elodea was replaced with animal cells in the experimental test tube?
If Elodea was replaced with animal cells in the experimental test tube, you would not observe the same process of photosynthesis. Animal cells do not carry out photosynthesis like plant cells do, so there would be no oxygen bubbles produced as a result of photosynthesis. Instead, the animal cells would likely undergo cellular respiration, using oxygen and producing carbon dioxide.
Carbon dioxide is passed into a solution of bromthymol blue indicator until the acid solution turns yellow A sprig of elodea is placed into yellow solution and it turns blue purpose of experiment is?
The purpose of the experiment is to demonstrate the process of photosynthesis. When the elodea plant is added to the yellow solution (indicating acidity), it will consume carbon dioxide and release oxygen through photosynthesis. This will cause a color change in the solution from yellow to blue as the pH increases due to the removal of carbon dioxide.
Which orgnisms demonstrates locomotion amoeba or elodea?
Amoeba demonstrates locomotion by crawling and changing shape using pseudopods, while Elodea does not demonstrate locomotion as it is a stationary aquatic plant.
