How did the invention of the light microscope
lead to the development and refinement of cell
theory over time?
A. Cells could now be seen in very low light so
that studies of reproduction could take place at
night
B. Light microscopes allowed for the visualization
of internal cell parts at magnifications over
1,000 times
C. As microscopes became more powerful,
scientists could see additional structures and
functions within the cell.
D. Scientists kept what they saw through the lens
of the light microscope to themselves to be sure
they got all the credit for the discovery,

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. Due to this, cell theory becomes more better and clear.
