Since the light compensation point occurs when the oxygen produced by photosynthesis is equal to the oxygen required for cellular respiration, oxygen will have a slope of 0.
Oxygen was produced by the elodea during photosynthesis while it was exposed to light.
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.
Elodea can float on water due to its buoyant nature. The leaves and stems are filled with air spaces that help them stay afloat. This characteristic allows the plant to access sunlight more easily for photosynthesis.
Yes. An organism is anything that is alive. What constitutes alive? Something that's alive fulfills these 7 requirements: Homeostasis. This means regulating the internal environment. Does Elodea regulate itself? Yes. Organization, or being made up of one or more cells. Elodea is made of cells. Metabolism, or making cells and energy. Does Elodea do this? Yes. Growth. Does Elodea grow? Yes. Adaptation, or being able to change in response to its environment. Can Elodea change in response to its environment? Yes. It will grow towards a source of light. Response to stimuli. Yes, Elodea does respond to stimuli. As mentioned before, it will grow towards light. Reproduction, or producing new organisms. Can Elodea reproduce? Yes. Elodea fulfills all of these conditions; therefore, it is alive and therefore an organism.
Yes, you could still calculate Elodea's rate of photosynthesis by measuring the change in dissolved oxygen in the water over time. The presence of single-celled protozoans would not significantly affect the ability to measure the rate of oxygen production by the Elodea.
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.
Elodea was placed in the flasks to study its role in photosynthesis and oxygen production. As an aquatic plant, Elodea can absorb carbon dioxide and release oxygen when exposed to light, making it an ideal specimen for experiments on these processes. Additionally, using Elodea allows researchers to observe the effects of varying light conditions or water quality on plant growth and respiration.

Oxygen was produced by the elodea during photosynthesis while it was exposed to light.
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.
The pH of the water will increase when elodea is exposed to light. This is because during photosynthesis, elodea will take in carbon dioxide, which will result in a decrease in carbonic acid concentration, leading to an increase in pH.

When a test tube of water containing elodea is exposed to bright light, the plant undergoes photosynthesis, producing oxygen gas, which forms visible bubbles. The rate of bubbling increases with the intensity of light; as the light source is brought closer, photosynthesis accelerates due to increased light energy. Conversely, as the light source is moved further away, the intensity decreases, leading to a reduced rate of bubbling. This experiment demonstrates the direct relationship between light intensity and the rate of photosynthesis in aquatic plants.
