Which tissue remains more active during autumn

Options

A. Vascular cambium
B. Cork cambium
C. Parenchyma
D. Sclerenchyma

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which tissue remains most active during autumn. We need to analyze the options provided to determine which tissue fits this description.

2. **Analyzing the Options**:
- **Vascular Cambium**: This tissue is responsible for secondary growth and is most active during spring when the plant is growing rapidly. It forms xylem and phloem tissues. Therefore, this option is incorrect.

- **Cork Cambium**: Also known as phallogen, cork cambium is responsible for producing the outer protective layer of the plant. It is particularly active during autumn as it helps in the formation of protective tissues in preparation for winter. This option is likely the correct answer.

- **Parenchyma**: This tissue is involved in various functions such as photosynthesis, storage, and healing. However, it is not a meristematic tissue and does not exhibit significant activity related to seasonal changes. Thus, this option is incorrect.

- **Sclerenchyma**: This is a type of simple tissue that consists of dead cells and provides structural support. Since it is composed of dead cells, it cannot be metabolically active. Therefore, this option is also incorrect.

3. **Conclusion**: After analyzing all the options, the tissue that remains most active during autumn is **Cork Cambium** (Option B).

### Final Answer:
The tissue that remains more active during autumn is **Cork Cambium**.
