Options

A. More, late
B. More, early
C. Less, late (autumn)
D. less, early

Answer

**Step-by-Step Solution:**

1. **Understanding Cambium Activity**: Cambium is a layer of tissue in plants that is responsible for secondary growth. Its activity varies with seasons, being more active in spring and less active in winter.

2. **Identifying Winter Season Characteristics**: During the winter season, the cambium's activity decreases significantly due to the cold temperatures and reduced metabolic processes in plants.

3. **Types of Wood Produced**: The wood produced by cambium can be categorized into two types based on the seasons:
- **Spring Wood (Early Wood)**: This is produced when cambium is highly active, typically in the spring and summer. It is lighter in color and has larger vessels.
- **Autumn Wood (Late Wood)**: This is produced when cambium is less active, typically in the autumn and winter. It is darker in color and has smaller vessels.

4. **Conclusion**: Given that the question specifically pertains to the winter season, we conclude that during this time, the cambium is less active and produces late wood.

**Final Answer**: In winter season, cambium is **less** active and produces **late** wood.
