Why is hydrilla stem cut underwater in photosynthesis experiment?
Cutting the stem of hydrilla underwater can prevent air bubbles blocking the xylem.
What did Jan Ingenhousz show?
He proved that Priestley's experiment only worked when plants were exposed to sunlight. Concluding that Priestley had not performed his experiment without sunlight. Ingenhousz performed both in sun and dark presence.
When NaHco3 is added to an elodea plant what happens?
Photosynthesis occurs and oxygen bubbles are produced.
How do you measure the rate of photosynthesis?
ANSWER 1get a beaker full of water then put the plant into it with a test tube of water on it. then put some light an it and blow into the water with a straw. if you see bubbles building up in the tube then you have oxygen.ANSWER 2Hi photosynthesis measurer,Counting the air bubbles that are produced when a plant is in water is perfect for measuring the rate of photosynthesis if you have limited resources and only need rough estimates. However, since bubbles have a variable, undefined volume, counting the number of air bubbles is not precise. You can obtain slightly more accurate results by collecting the air released, and measuring the volume.If you wish to obtain precise and accurate measurements of the rate of photosynthesis, you could use a Photosynthesis Measurement System. They are instruments that quantitatively measure the rate using an infrared gas analyser to assess the input of CO2 and output of H2O. Some Photosythesis measurement systems (such as the LCpro+) offer the ability to precisely control the environment of the leaf being measured. These instruments maintain the leaf chamber at user-selected concentrations of CO2 and H2O, and can control PAR and temperature. This allows you to conduct detailed experiments on the effects of different conditions on the rate of photosynthesis.Photosynthesis measurement systems are designed to be portable so you can carry them to field sites (except some models are somewhat heavy for field work. LI-COR's 6400 model weighs 13.5kg!).Answer 3Below is a reference site that might be helpful.
What is used to measure the rate of photosynthesis?
Special equipment exists for measuring the rate of photosynthesis. For precise and accurate measurements, use a Photosynthesis Measurement System. They quantitatively measure the rate using an infrared gas analyser to assess the input of CO2 and output of H2O. Some Photosynthesis Measurement Systems (e.g. the LCpro+) can precisely control the environment of the leaf. The user can select the exact concentrations of CO2 and H2O, and can control PAR and temperature, so can investigate the effects of different conditions on the rate of photosynthesis.Some Photosynthesis Systems are portable so you can carry them to field sites (but some are somewhat heavy for field work. LI-6400 model weighs 13.5kg)Alternatively, you can assess photosynthetic rate by measuring the volume of gas produced by an aquatic plant. This is perfect for investigating the rate of photosynthesis if you have limited resources, don't need high levels of accuracy, and don't care which species of plant you study.To do this experiment; Cut the stem of an Elodea plant diagonally. Put it in a small graduated cylinder full of water without introducing any bubbles. Invert the cylinder into a beaker full of water with the top covered so no air gets in. Place the beaker in light. Either count the number of bubbles produced, or leave the experiment for a long time and measure the volume of gas produced. Since bubbles have a variable, undefined volume, counting the number of air bubbles is not precise.
Why is hydrilla stem cut underwater in photosynthesis experiment?
Cutting the stem of hydrilla underwater can prevent air bubbles blocking the xylem.
What if your pondweed experiment had only a few big bubbles?
Less oxygen is being produced at a slower rate
What is the role of hydrilla experiment in the law of limiting factors?
The law of limiting factors is that at a given time, only the factor that is most limiting among all will determine the rate of photosynthesis. The role of the hydrilla experiment in the law is that it shows how photosynthesis works in the form of oxygen bubbles.
What is the gas in the bubbles from photosynthesis?
Photosynthesis produces oxygen.
What gas is represented by bubbles in an experiment?
Which experiment?
What does a spell look like underwater?
Hot bubbles
How do you get to the underwater cave in mythology island poptropica?
You have to swim through an underwater maze. Pop bubbles for oxygen.
What does a photosynthesis look like?
You can not see photosynthesis but you can see its results. Algae in water exposed to sunlight will give off bubbles. These bubbles are made of Oxygen gas. The Oxygen is a waste product of the photosynthesis process.
How is the number of bubbles produced by the plant related to the rate of photosynthesis?
One of the products of Photosynthesis is oxygen (Carbon Dioxide and Water give Glucose and Oxygen) and the bubbles you see coming from pond weed are actually the oxygen being produced from Photosynthesis. So therefore, the more/faster the bubbles, the quicker Photosynthesis is happening.

What can you tell anout photosynthesis if a leaf begins to produce more gas bubbles?
The increase in the rate of gas production (oxygen) leads to the conclusion, that the rate of photosynthesis is increasing. As the rate of the products being released (the bubbles) increases that signifies that the cycle is speeding up, thus a greater amount of photosynthetic cycles are occurring.
How to swim underwater without holding your nose?
This is the easiest way to not hold your nose underwater. When you go underwater, blow bubbles out of your nose. This will prevent the water from entering your nose. Just blow bubbles out of your nose frequently and no water will get up your nose.
