So here we have been asked questions which are related to photosynthesis and respiration.
00:12
So our first question is telling us that a fish and an aquatic plant they are placed in a closed tube with a bright light source.
00:34
And what changes we will be seeing or we would expect to occur if we do the further experiment regarding this for the concentration of oxygen and carbon dioxide.
01:01
So first of all, if we talk about this experiment, then this experiment is similar to experiment.
01:12
Which was done by tristley named as the bell jar experiment and this experiment was done to show the importance of oxygen.
01:40
Now here the case is different.
01:44
That is we are using a fish and an aquatic.
01:50
Plant.
01:52
So basically if we talk about aquatic plant then since it has green leaves which will do the process of photosynthesis because a light source is already present there.
02:26
And if we talk about the carbon dioxide, then this fifth, this fifth.
02:34
Is respiring in which releases carbon dioxide.
02:49
Now this carbon dioxide along with the light source and with the help of the enzymes or we can say cells which are present in the leaves they do the process of photosynthesis.
03:10
Now after the process of photosynthesis, the result of photosynthesis is that it releases some amount of water along with oxygen, that is free oxygen.
03:38
Now this free oxygen is consumed by fish to survive there.
03:51
So this is how the whole cycle occurs and if we talk about the concentration, then we can tell that the concentration of oxygen is greater as compared to the carbon dioxide concentration.
04:26
This is because the oxygen is released from the plants and they release a large amount of oxygen as compared to the carbon dioxide which is being released by the fish during the process of respiration.
04:42
So this was our conclusion regarding the first question.
04:46
Now coming to the second question, it is telling that there is a photosynthesis lab...
