Your explanation is awesome. This is the gold standard to water other respirometers should be held too. Also, I have seen many fails in my 56 y.o lifetime of water respirometer

some books says as CO2 would be replaced by water then we would measure the volume of water . Is It correct ?If water comes inside, the water goes in to cotton and base so that the organism will be affected by the base . How do You explain this . From the beginning , how water enters in to the system while the system is closed ?

@ievaarmalyte2087 4 жыл бұрын

What is the reason that the volume of seeds is measured and not the mass?

@sciencemusicvideos 4 жыл бұрын

This is a great question, Leva. You could measure cellular respiration by the loss of dry weight (as carbohydrate is turned into carbon dioxide and water). But because the seeds are wet, it would be very hard to measure a before and after difference in such a short time frame, and water would confuse your results. It's much easier to measure the decrease in volume, and because we use KOH (which absorbs all the carbon dioxide), then the change in gas volume can be attributed to consumption of oxygen during respiration. Hope that helps! Mr. W

Hello! I am taking a test with a similar experiment, but they rinsed the seeds in diluted bleach. Why would they do that?

@tadi17k 3 жыл бұрын

to kill bacteria and other organisms on the seed because they can also respire.

Thanks alot for the video i just want to share this scripture John3:36 "He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him." Seek Jesus and flee form the wrath to come, Repent and be baptised in the name of Jesus Christ. Mat 16:24 "Then said Jesus unto his disciples, If any man will come after me, let him deny himself, and take up his cross, and follow me."
