Option C. As microscopes became more powerful, scientists could see additional structures and functions within the cell.
Explanation:
Light microscope is also called optical microscope which is used to see very small objects which can't be seen through naked eyes. The magnification power of light microscope is 1000x which means light microscope show the object 1000 times greater than its original size. Due to this magnification power, scientists are able to see many new features of the cell which cannot be seen with ordinary microscope.
