Quizplus · Accepted Answer

This description fits the outer segment of a photoreceptor cell, specifically the rods and cones found in the retina of the eye. The membranous discs contain the light-sensitive pigments that allow for vision, and the connecting stalk attaches the outer segment to the inner segment, which contains the cell's nucleus and other organelles. Bipolar cells, ganglion cells, amacrine cells, and horizontal cells are all types of interneurons in the retina that are not directly involved in detecting light.
