Differentiation of various tissue and organs in respone to light is called

Options

A. morphogenesis
B. photomorphogenesis
C. organogenesis
D. embryogenesis

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes the differentiation of various tissues and organs in response to light. This involves understanding how organisms, particularly plants, develop in relation to light.

2. **Identifying Key Terms**:
- **Differentiation**: This refers to the process by which cells or tissues develop into different types or functions.
- **Response to Light**: This indicates that the development is influenced by light, which is a critical factor for plants.

3. **Exploring the Options**:
- **Morphogenesis**: This term refers to the shaping and development of an organism but is not specifically tied to light.
- **Photomorphogenesis**: This term directly relates to the development of plants in response to light. It involves how light signals affect the growth and differentiation of plant tissues and organs.
- **Organogenesis**: This refers to the formation of organs but does not specifically indicate a light-dependent process.
- **Embryogenesis**: This is the process of embryo development, which is also not specifically related to light.

4. **Selecting the Correct Answer**: Among the options, **photomorphogenesis** is the term that specifically refers to the differentiation of tissues and organs in response to light. It is primarily observed in plants.

5. **Final Answer**: The correct answer is **photomorphogenesis**.
