Explain the importance of optics development for biology (microscope)

Optic microscopes are one of the most important tools to diagnose tissue samples,  to discover the existence of  microorganisms and then study them, study the structure of the cells, and to see other smaller parts of plants,  fungi and animals. Through the development of this microscope, and the others, we discover more and more small objects not visible to the naked eye but that they exist.

By using microscopes scientists were able to discover the existence of microorganisms, study the structure of cells, and see the smallest parts of plants, animals, and fungi. Today, the microscope is still a commonly used tool to diagnosis illness in hospitals and clinics all over the world.

Redshift happens when light or other electromagnetic radiation from an object is increased in wavelength, or shifted to the red end of the spectrum
