Joseph Priestley's experiment on photosynthesis involved placing a plant (mint) inside a sealed container with a burning candle, and observing that the candle's flame eventually went out. He concluded that the plant was releasing oxygen during photosynthesis, which allowed the candle to burn. This experiment helped in understanding the relationship between plants and the air they breathe.
When Joseph Priestley, an Englishman, discovered oxygen in 1774, he answered age-old questions of why and how things burn. He did this by systematically analyzing the properties of different "airs" using an inverted container on a raised platform. The container captured the gases produced by the various experiments below it. The container could also be placed in a pool of water or Mercury, sealing it, and then the gas tested to see if it would sustain a flame or support life.

Can plant carry out photosynthesis using artificial light?
Yes, plants can carry out photosynthesis using artificial light. As long as the light contains the necessary wavelengths (blue and red light are most important), plants can use it to convert carbon dioxide and water into glucose and oxygen through photosynthesis. However, natural sunlight is the most effective source of light for plant growth and development.
What is its called when a scientist makes a mistake and has to do the experiment?
When a scientist makes a mistake and has to redo an experiment, it is often referred to as a 'control experiment' or a 'repeat experiment'. This is done to ensure the accuracy and reliability of the results by verifying the consistency of the findings.
What is experiment set-up?
An experiment set-up refers to the specific arrangement of equipment and materials used to conduct an experiment. It includes variables being tested, controls, measurement tools, and the overall procedure followed to collect data and analyze results. A well-designed experiment set-up is crucial for ensuring the validity and reliability of the outcomes.
How are the rate of photosynthesis and the growth rate of grass related -?
The rate of photosynthesis in grass directly affects its growth rate. Photosynthesis is the process by which plants produce energy to grow, so a higher rate of photosynthesis typically results in faster growth. Factors like light intensity, temperature, water availability, and nutrient levels can influence both photosynthesis rate and grass growth rate.
Why is control important in an experiment?
Control is important in an experiment to eliminate the influence of variables other than the one being tested. By having a control group that is not exposed to the experimental treatment, researchers can accurately gauge the true effect of the independent variable on the outcome. This allows for valid and reliable conclusions to be drawn from the experiment.
What priestley had done to introduce mint plant without disturbing experimental set up?
Can you answer
What is done in an experiment?
The reason for the experiment is to answer the problem
When did Ben Franklin performs famous kite experiment?
Unfortunately, Franklin's original account of this experiment only stated that it had been done in Philadelphia, without any mention of where or when it was done, or even by whom. The only statement that Franklin did so came 15 years after the fact from Joseph Priestley, a close friend who claimed to be writing down the verbal account of Franklin's. Priestley stated that Ben, when deciding to do the experiment, chose "to take a walk in the fields, in which there was a shed convenient for his purpose." This could have been just about anywhere in the Philadelphia area.
Where are most experiment done explain the benefits of this choice?
Experiment done the most is doing hypothesis
Who are three scientists that contributed to our knowledge on photosynthesis?
Three scientists that contributed to our knowledge on photosynthesis are: Jan Ingenhousz, who discovered the role of sunlight in photosynthesis. Melvin Calvin, who elucidated the Calvin cycle, the process by which plants fix carbon dioxide during photosynthesis. Rudolph A. Marcus, who developed the theory of electron transfer reactions in photosynthesis, explaining the mechanism by which plants convert light energy into chemical energy.
What are necessary precautions for safety purposes while conducting an experiment?
The necessary safety precautions when conducting an experiment depend on what is done during the experiment and where it is done.
What is the deffintion of controlled experiment?
a controlled experiment is an experiment that has an iv, dv, and a control, is in a well handled environment, and the experiment is safely done.
What is intended to be done in an experiment?
It is the "aim"
Do all experiment have to be done in a lab?
No
How deforestation related to photosynthesis?
Since trees can do photosynthesis, cutting down trees will decrease the amount of photosynthesis being done.
Who is photosynthesis?
Photosynthesis is not a person. It is a process done by plant to get energy
What should be done after colecting data for an experiment?
The data should be organized and the experiment's materials cleaned?
