Question

Rods and cones of retina are modified

• A. Bipolar neurons
• B. Unipolar neurons
• C. Multipolar neurons
• D. Hairs

Answer 1

The correct option is A Bipolar neurons

• A bipolar neuron is a nerve cell that has one axon and one dendrite.
• A unipolar neuron is a nerve cell that has only one protoplasmic process called neurite attached to their body.
• A multipolar neuron is a nerve cell that has single axon and many dendrites.

Rods and cones are the photoreceptor cells in the retina of eye associated with low light vision and daylight vision respectively. They are modified bipolar neurons because they have modified dendrites.

So, the correct answer is 'Bipolar neurons'.
