The complex tissues include

Options

A. Scleroids
B. Sclerenchyma
C. Secretory tissue
D. Collenchyma

Answer

**Step-by-Step Solution:**

1. **Understanding Complex Tissues**: Complex tissues in plants are made up of more than one type of cell and perform specific functions. They are essential for the growth and development of plants.

2. **Identifying the Options**: The options provided are:
- A) Scleroids
- B) Sclerenchyma
- C) Secretory tissue
- D) Cholenchyma

3. **Analyzing Each Option**:
- **Scleroids**: These are also known as stone cells. They are a type of sclerenchyma and are not classified as complex tissues on their own.
- **Sclerenchyma**: This is a type of supportive tissue in plants, consisting of dead cells that provide strength. However, it's not classified as a complex tissue by itself.
- **Secretory Tissue**: This is a type of complex tissue that includes glandular tissues (like glands and trichomes) and latticiferous tissues (which include ducts). These tissues are responsible for the secretion of various substances.
- **Cholenchyma**: This is a living supportive tissue that provides flexibility and is characterized by elongated cells. While it is a complex tissue, it is not the correct answer in this context.

4. **Conclusion**: The correct answer to the question "The complex tissues include" is **C) Secretory tissue**.
