During the course of development, cells in various regions of embryo became variable in morphology and eventually perform diverse functions. This process is known as

Options

A. Rearrangement
B. Differentiation
C. Metamorphosis
D. Organisation

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question describes a process that occurs during the development of an embryo, where cells become variable in shape and function.

2. **Identifying Key Terms**: The key terms in the question are "development," "cells," "variable in morphology," and "diverse functions."

3. **Analyzing the Options**: The question provides four options:
- **Rearrangement**: This refers to changes in chromosome structure, which is not relevant to the development of cell functions.
- **Differentiation**: This is the process where less specialized cells become more specialized and take on distinct functions.
- **Metamorphosis**: This refers to a significant change in form after birth or hatching, such as in insects, and does not apply to embryonic development.
- **Organization**: This refers to the arrangement of parts for function but does not specifically address the specialization of cells.

4. **Selecting the Correct Answer**: Based on the analysis, the process where cells in various regions of the embryo become specialized in morphology and function is known as **differentiation**.

5. **Conclusion**: Therefore, the correct answer to the question is **differentiation**.
