Differentiation of callus into plant parts is

Options

A. Embryogenesis
B. Embryoid formation
C. Morphogenesis
D. Totipotency.

Answer

**Step-by-Step Solution:**

1. **Understanding Callus Formation:**
- Callus is a mass of undifferentiated cells that forms when plant tissues are cultured in vitro. This can occur when a plant is wounded or during tissue culture techniques.

2. **Differentiation Process:**
- Differentiation refers to the process by which unspecialized cells (like those in a callus) develop into specialized cells or tissues, such as roots, shoots, or leaves.

3. **Role of Plant Growth Regulators:**
- The differentiation of callus into specific plant parts is influenced by plant growth regulators (hormones). These hormones guide the cells to develop into the desired structures.

4. **Identifying the Correct Term:**
- The question asks for the term that describes the differentiation of callus into plant parts.
- The options given are:
- A. Embryogenesis
- B. Embryoid formation
- C. Morphogenesis
- D. Totipotency

5. **Analyzing the Options:**
- **Embryogenesis:** This refers to the process of embryo formation, not specifically the differentiation of callus.
- **Embryoid Formation:** This relates to the formation of structures resembling embryos, but does not specifically denote the differentiation of callus.
- **Morphogenesis:** This term specifically refers to the process by which cells differentiate into specific structures, such as roots and shoots, from a callus.
- **Totipotency:** This refers to the ability of a single cell to develop into a whole organism, which is broader than just the differentiation of callus.

6. **Conclusion:**
- Based on the definitions and the context of the question, the correct answer is **C. Morphogenesis**, as it specifically describes the differentiation of callus into various plant parts.

**Final Answer:** C. Morphogenesis
