Which study would include the examination of cell organelles?

The study that would include the examination of cell organelles is cytology. Cytology focuses specifically on the structure, function, and behavior of cells, including their organelles, which are specialized subunits within a cell that perform various functions essential to cell maintenance, growth, and communication.

Through cytological techniques, scientists and medical professionals can observe and analyze the appearance and activity of these organelles, such as mitochondria, endoplasmic reticulum, and Golgi apparatus, to understand their roles in health and disease. This makes cytology the most appropriate field focused on the intricacies of individual cells and their internal components, while other fields, like histology, concentrate on tissue structures, neurophysiology emphasizes nervous system function, and physiology studies the functions of the broader biological systems rather than focusing on cellular details.
