The stages of mitosis were originally defined by cellular features observable through a light microscope.
Brrunno [24]

Answer: TRUE

Explanation:

The cell division that takes place during the growth and development of an organism is in an as MITOSIS. Mitosis takes place in somatic cells that is, body cells that are not involved in the production of gametes. The difference stages of mitosis were originally defined by cellular features observable through a LIGHT MICROSCOPE. These stages includes:

--> PROPHASE: when viewed under a light microscope, each chromosome shortens and thickens and is seen to consist of two chromatids. The Centriole begin to separate.

--> METAPHASE: The nuclear membrane disappears, a spindle forms, the chromosomes line up across the middle of the cell and become attached to the spindle fibres at their centromeres.

--> ANAPHASE: The sister chromatids are pulled apart to opposite ends of cell as the spindle fibres contract.

--> TELOPHASE: A nuclear membrane forms around each set of chromatids, and the cell divides into two daughter cells.
