Final answer:
Microscopes are used to investigate cell structure in biology. They allow scientists to magnify microorganisms, human cells, and tissues to study their form and structure.
Step-by-step explanation:
Microscopes are used to investigate cell structure in biology. They allow scientists to magnify microorganisms, human cells, and tissues to study their form and structure. Stains and dyes are often used to add color to microbes for better observation. Microscopes are essential tools in biology laboratories for studying the tiniest living beings.
