Question

which statement is true about cell differentiation?
it causes cells to change and specialize.
it produces identical cells.
it happens in all cells.
it happens during cell division.

Explanation:

• Analyze each option:
• "It causes cells to change and specialize": Cell differentiation is the process where cells develop distinct structures and functions, so this matches the definition.
• "It produces identical cells": Cell division (like mitosis) produces identical cells, not differentiation.
• "It happens in all cells": Not all cells differentiate (e.g., some adult stem cells or fully differentiated cells don't re - differentiate in normal circumstances).
• "It happens during cell division": Differentiation occurs after cell division as cells start to specialize, not during the division process itself.

Answer:

It causes cells to change and specialize.
