Question

Explain why cells do not all look the same. (Simple answer)

Answer 1

Cells do not all look the same because they have different functions and roles in an organism. Variations in shape, size, and structure arise from differences in gene expression, which determines how cells develop and what proteins they produce. For example, muscle cells are long and flexible for movement, while nerve cells have long extensions for signaling. This diversity allows different cell types to perform specialized tasks efficiently.
