Final answer:
Whole mounts are intact objects observed in a microscope, providing a complete view of the specimen. They are commonly used for studying small organisms like protozoans.
Step-by-step explanation:
Whole mounts are intact living or dead objects that are observed in a microscope, which can be a complete organism or a small part of a larger organism. They provide a full view of the specimen and are commonly used for studying small organisms like protozoans. Compared to sections or resections, which are thin slices of the specimen, whole mounts allow for a more comprehensive examination.
