Question

Largest cell in the body is
A. Lymph
B. Osteocyte
C. Neuron
D. Chromatophore

Answer 1

Hint: The cell is the functional and the structural unit of life and the living body. They are known as the structural unit because it is the smallest unit in any organism capable of sustaining life. It is known as the functional unit because it can perform all the basic functions necessary to life.

Complete step-by-step answer:
Neurons are nerve cells. These cells make up the nervous system of our body. These cells are therefore found in the brain and the spinal cord. They are the longest and the largest cells in the body. Sometimes they grow to the length of several feet. These cells do not divide and replicate and are an exception to the cell theory.
Neurons are made up of two parts. These two parts are the cyton or the cell process or cell bodies. Cyton is the flat part that is also known as the soma or perikaryon. The cell process is divided further into dendrites and axons. The cyton has a nucleus, Nissl’s granules for protein synthesis, cytoplasm, and several dendrites originating from the cyton to help in the impulse conduction. The cell body has a long part axon. The axoplasm along with its layer is known as axolemma. Axolemma has Schwann cells for the formation of the myelin sheath to prevent the leakage of signals. The point where this sheath is absent is known as the Node of Ranvier.

Thus, based on the above information we can conclude that the largest cell in the body is the neuron.

Hence, the correct answer is an option (C).

Note: Chromatophore cells are present in the retina of the eye. These cells contain black pigment. They help in reflecting the light. Chromatophore cells are sometimes one of the largest cells at maturity. However, immature chromatophores are small in size. Also, all chromatophores do not become large at maturity. Due to this reason, the correct answer is the neuron.
