 Today the practical name is wet mount preparation. So first we enter our record, the date, the time interval and the experiment name in the logbook for the proper record. So in wet mount we have to prepare a slide and the material required for this. The slides cover slips, the specimen which is in the form of pond water and for taking the specimen dropper could be used but here for the proper measurement we are using a pipette and the tips. Now the procedure, I have set the pipette for the proper measurement on the 100 micro litre and I will take 100 micro litre of the pond water on a clear slide and we will put the water and discard the tip then we will cover it with the cover slip, we will be careful there should be no air bubble inside. The importance of the wet mount is we can see here not only the structure but also the movement of the microorganisms first we will set our slide and we will see under the magnification power of 4x we will record our observations in our data book or the practical copy that either the organism was moving, what was the shape of organisms, there are various organisms that's for example different type of algae and different small astroports we can visualize in the pond water depending upon the which type of pond water we are observing here. Here I have taken the pond water the fish pond water and I am observing now by changing the 10x I have visualized more better view and we will record by observation 10 by changing different type of moving bodies on the 40x movement was present there are some algae type and various shapes of the bacteria then under the observation of 100x first I have to apply the oil immersion one drop of oil immersion is enough for visualization it is important to note that we have to see and visualize in a zigzag view so that the zigzag view we can go upward and downward or from left to right or from right to left but in a proper way so that pool slide would be visualized and the observation become the perfect so dear students in this way we are using the wet mound for proper observation of the organisms so at the end we have to once again prepare the desk for next user we will discard and prepare our desk
