Question

Identify the odd term in the set given and name the category to which the remaining three belong.

• A. Cyton
• B. Photon
• C. Axon
• D. Dendron

Answer 1

The correct option is B

Photon

The correct option is B.

The explanation for the correct option:

1. Photons are subatomic particles or light particles.
2. They carry the electromagnetic force.

The explanation for the incorrect options:

Option A:

1. The neuron is the structural and functional unit of the nervous system.
2. The swollen part of a typical neuron, containing cytoplasm and nucleus, from which cellular processes emerge is called the cell body or cyton.

Option C:

A long cellular process emerging from a cyton, which transmits nerve impulses from the cell body or cyton to another neuron is known as an axon.

Option D:

The short cellular processes emerging from the cyton of a neuron that receives impulses from another neuron are called dendrons.

Final answer:

Hence, the odd term is Photon(subatomic particle); while the rest of the terms are associated with the neurons.
