What are the types of cells found in human eye? Please explain.

Solution:
 

• There are two types of light-sensitive cells in the human eye.
• They are found in the retina.
• They are called rods and cones.
• The rods (rod-shaped cells) present in the retina are sensitive to dim light and are responsible for vision in dim light.
• The cones (cone-shaped cells) present in the retina are sensitive to bright or normal light and are responsible for colour discrimination and colour vision.
