cell biology: meaning, definition, pronunciation and examples

No, they overlap significantly but have different focuses. Cell biology studies the entire cell, its organelles, and its life cycle, often using microscopy. Molecular biology focuses more narrowly on the molecular machinery (like DNA, RNA, proteins) and their interactions within the cell.

Almost never. It is an uncountable noun referring to the discipline. You would not say 'three cell biologies'. However, you might refer to different 'areas' or 'branches' of cell biology.

'Cytology' is an older term that traditionally focused more on the structure (morphology) of cells, often in a medical diagnostic context (e.g., Pap smear). 'Cell biology' is a broader, modern term encompassing structure, function, biochemistry, genetics, and physiology of cells.

When used as a standalone noun phrase, no hyphen (e.g., 'I study cell biology'). When used attributively before another noun, a hyphen is often used for clarity (e.g., 'a cell-biology textbook'), though omitting it is also common ('a cell biology textbook'). Check specific style guides.
