It gives a high magnification necessary for working out the details of minute organisms and also for studying the internal structures of plants and animals. The instrument rests on a horse-shoe-shaped base (foot) with [...]
Get the answer of: How to prepare a live specimen for microscopic study. A. Whole Mount Preparation: Killing and fixing: In case of live specimens they are to be killed. Killing must be instantaneous. This is done with chloroform, ether, acetone, alcohol, formalin, menthol, Bouin's fluid, etc. These chemicals serve as fixatives also. Specimens contracting or retracting suddenly in contact [...]
