Question

The smallest size of a cell which can be seen with unaided eye is or differentiation capacity of human eye is

• A. 1 micron
• B. 10 micron
• C. 100 micron
• D. 1000 micron

Answer 1

Answer: (C)

100 micron

• A cell is a microscopic unit that can be visible under a microscope. The resolving power of the eye lens is the ability of the lens to distinguish an object as a separate image.
  
• The human eye has a convex lens, and the visibility of the eye depends on its resolving power. The smallest size of a cell that can be seen with the unaided eye is or the differentiation capacity of the human eye is 100 microns.

Thus the correct answer is option C.
