You don't have to its just to see the different cycles.
Do not touch lenses. ALWAYS start with the least magnification, and work upwards. Clean slides and microscope when finished with it. Cover microscope with dust cover when not in use. Never swing the microscope.
On where you start is totally optional, but it is most beneficial to start on the lowest power, so that you can adjust your magnification from then on to make out the object your trying to see. Start low then work your way to high.
start by focusing with the lowest lens to make sure the slide is right and you can see the specimen them proceed to the next lens power and focus again just to make the view clear then proceed to the highest and focus one more time
Only if they are at the start of a sentence. Otherwise they are not capitalised.
Actually, it depends on the specimen which you are observing.. Suppose, if you are observing Tissues then you have to switch to 10X objective; but if you are observing mammalian cells or other cellular specimen then you have to switch to 45X objective...But, if you want to observe microbial cells then you have to put a drop a drop of paraffin oil on the smear made on the slide and then observe it into 100X oil immersion objectivelens...
Lowest power
low power
The reason we start on low power adjective on a microscope is because if we put it on high power the power may go down and we then have to charge it. from: Alexislily1 over and out
because it allows you to find the part of the slide you want to see, then you can zoom in by changing focus to see the frame in greater detail. if you don't start in low power it is extremely difficult to move around the slide

The higher the power, the more difficult it is to have the item being viewed centered in the viewing field. However at lower power the viewing angle is wider and it is easier to find and position the item in the field. So we start by centering the item in the field at lower power, increase the power and center it again.
Questions almost always start with Who, What, When, Where, Why, How, Was, Is, Are, If, Do, Did, Can, Could, Would or Should
You should always check your gauges, seat belt, and mirrors after you start your car.
start with the low power objective
You need to find that you want to see first and then you can move to higher power to see it in more detail.
