Multiple Choice
In humans, which cell type is generally considered the largest cell in the body by volume?
A
Erythrocyte (red blood cell)
B
Neuron (motor neuron cell body)
C
Oocyte (egg cell)
D
Skeletal muscle cell (myofiber)
Verified step by step guidance1
Step 1: Understand the question is asking about the largest human cell by volume, not by length or surface area.
Step 2: Review the characteristics of each cell type listed: erythrocytes are small and lack a nucleus, neurons have large cell bodies but are elongated, skeletal muscle cells are long and multinucleated but relatively thin, and oocytes are single large cells designed to store nutrients for early development.
Step 3: Recall that the oocyte (egg cell) is known to be the largest cell in the human body by volume because it contains a large amount of cytoplasm and nutrients to support early embryonic growth.
Step 4: Compare the typical sizes: erythrocytes are about 7-8 micrometers in diameter, neurons vary but their cell bodies are smaller than oocytes, skeletal muscle cells are long but thin, and oocytes can be around 100 micrometers in diameter, making them much larger in volume.
Step 5: Conclude that the oocyte is the largest human cell by volume due to its size and function, which matches the correct answer provided.
