Early wood is formed

Options

A. in winter
B. In spring
C. Throughout the year
D. In Autumn

Answer

**Solution:**

1. **Understanding Wood Formation**: Wood is formed by the activity of the cambium, a layer of tissue in plants that produces new cells. The cambium's activity varies throughout the year, leading to the formation of different types of wood.

2. **Cambium Activity**: The cambium exhibits irregular activity, meaning it is not consistently active throughout the year. It can be more active during certain seasons and less active during others.

3. **Spring Season**: During the spring season, the cambium is particularly active. This increased activity results in the production of a larger number of xylary elements (the cells that make up the wood).

4. **Characteristics of Early Wood**: The wood formed during this active period in spring is referred to as "early wood" or "spring wood." It is characterized by:
- A lighter color due to the wider cavities formed.
- Lower density because the cells are produced quickly.

5. **Conclusion**: Therefore, early wood is formed in the spring season when the cambium is most active.

**Final Answer**: Early wood is formed in **spring**.
