Cell Biology

The permanent library page for cell structure, division, and function — built to be bookmarked, cited, and returned to.

Intro Bio AP Biology Cell & Molecular Bio Nursing & Allied Health

From the folded membranes of the mitochondrion to the choreography of chromosomes during mitosis, the cell is where biology becomes visible. This hub collects Science Source's licensed photography, micrographs, and scientific illustration on cell structure and division — organized for instructors building lecture slides, textbook publishers sourcing figures, and students who want to see, not just read, how a cell works.

Every image below is cleared for educational licensing. Captions note magnification and imaging method where relevant, so you can judge fit for a syllabus or a printed page before you license.
