Cornea in human eye

Options

  1. Ais a light sensitive screen.
  2. Bis a muscular diaphragm.
  3. Ccontains blood vessels.
  4. Dis composed of proteins and cells.

Correct answer

D. is composed of proteins and cells.

Step-by-step solution

The cornea is composed of proteins and cells. It does not contain blood vessels, unlike most of the tissues in the human body. Blood vessels may cloud the cornea, which may prevent it from refracting light properly and may adversely affect vision.
