Complex tissues are

Options

A. 1)Xylem and phloem
B. 2)Heterogeneous tissues
C. 3)Conductive tissues
D. 4)All of these

Answer

**Step-by-Step Solution:**

1. **Understanding Tissues:**
- Tissues in plants are categorized into two main types: simple tissues and complex tissues.

2. **Defining Simple Tissues:**
- Simple tissues are composed of only one type of cell. These cells are structurally and functionally similar. Examples include parenchyma, collenchyma, and sclerenchyma.

3. **Defining Complex Tissues:**
- Complex tissues consist of more than one type of cell that work together as a unit. They are responsible for the transportation of organic materials, water, and minerals throughout the plant.

4. **Identifying Complex Tissues:**
- Complex tissues are also known as vascular or conductive tissues. The primary examples of complex tissues are xylem and phloem.
- **Xylem:** Conducts water and minerals from the roots to the rest of the plant.
- **Phloem:** Transports food materials (sugars) produced by photosynthesis from the leaves to other parts of the plant.

5. **Analyzing the Options:**
- The question provides four options regarding complex tissues:
1. Xylem and phloem
2. Heterogeneous tissue
3. Conductive tissue
4. All of these
- Since xylem and phloem are complex tissues, they are correct.
- Complex tissues are indeed heterogeneous, as they consist of different types of cells.
- They are also classified as conductive tissues, as they facilitate the transport of materials.

6. **Conclusion:**
- Therefore, the correct answer is option 4: "All of these," as all the statements regarding complex tissues are accurate.
