The various steps of observing leaf petal slide under a microscope are as follows :-
• Take a fresh leaf that must be green and alive and carefully with a blade, cut off a really small outer layer of the leaf's structure.
• Take a glass slide and put that peel on it. Add the stain as you like and glycerine too.
• Now cover it with a watch glass.
• Now take a microscope and adjust the mirror to allow sufficient light to enter the microscope, by watching through the eye piece.
• Now, as you like, rotate the various screws until you are able to see the required observation.
