Final answer:
The specialist in the microscopic study of cells and tissues is called a cytotechnologist.
Step-by-step explanation:
Cytotechnologists are professionals who use microscopes and laboratory tests to examine cells. They are trained to identify normal and abnormal cellular changes and often work in collaboration with pathologists to make diagnoses.
Cytotechnologists study cellular specimens obtained from various organs in the body. They analyze these specimens under a microscope to identify any abnormal cellular changes that may indicate the presence of diseases such as cancer. When abnormalities are detected, they consult with pathologists, who are medical doctors specialized in interpreting and diagnosing changes in body tissue and fluids. So therefore cytotechnologist is the specialist in the microscopic study of cells and tissues.
