Question 9

The retina contains two types of photoreceptor cells, labeled Cell P and Cell Q in the diagram below.

Diagram showing two types of light-sensitive cells in the human retina. Cell P is long, thin, and cylindrical with disc-like structures inside its outer segment. Cell Q has a wider, conical outer segment. Both cells contain a nucleus and synaptic terminals.

Cell Q is responsible for colour vision and functions best in bright light. Name the type of photoreceptor represented by Cell Q.
