Under a light microscope, a stained cell shows chromosomes lined up along the middle. What will happen next? Spindles will form and centrioles will move to opposite poles. A nuclear membrane will form around each set of chromosomes. Chromosomes will separate and move to opposite poles.

Chromosomes will separate and move to opposite poles.

A light microscope uses focused light and lenses to magnify an object. Light microscopes come in several forms. (1) Simple light microscopes use a single lens to magnify an object and cannot reach high magnification just like a handheld lens whose highest clear magnification in the best conditions is 25x. (2) Compound light microscopes use two sets of lenses - an objective lens and an eye piece. This is the type of light microscope whose magnification power reaches between 1000x and 2000x.
