Cell Biology MCQ question and answer with solution | Biology Gk MCQs

Among the given options, the nerve cell (neuron) is the largest cell in the human body in terms of length.

Some neurons, especially those extending from the spinal cord to the toes, can be more than one meter long. This makes them the longest and largest cells in the human body.

Nerve cells are specialized for the transmission of electrical impulses and consist of a cell body, dendrites, and a long extension called the axon, which is responsible for their remarkable length.

Muscle cells, liver cells, and kidney cells are important body cells but are much smaller in length compared to neurons.

Exam Tip: In general biology, the ovum (egg cell) is considered the largest cell in the human body by diameter, whereas the nerve cell (neuron) is considered the largest or longest cell by length. Since the ovum is not among the options, nerve cell is the correct answer here.

Therefore, Option A (Nerve cell) is the correct answer.
