KK: /sīˌtōfōtəˈmetrik/
Relating to a method of measuring the properties of cells using light.
The cytophotometric analysis revealed important information about the cell structure.
Cytophotometric → It is formed from "cyto-" (from Greek "kytos", meaning cell) and "photometric" (from Greek "photos", meaning light, and "metron", meaning measure). The word refers to the measurement of light in relation to cells.
Think of 'cells' ('cyto-') being measured by 'light' ('photo') — that's what cytophotometric means.
