Options

A. It is very soft
B. It appears lik a sponge
C. It can be bent easily
D. It does not process vessels

Answer

To solve the question about why the wood of gymnosperms is known as softwood, we can analyze each option provided:

1. **Understanding Gymnosperms**: Gymnosperms are a group of plants that produce seeds without flowers or fruits. Their wood is referred to as "softwood."

2. **Evaluating the Options**:
- **Option (a)**: "It is very soft."
- While softwood is generally softer than hardwood, this is not the primary reason for the classification.
- **Option (b)**: "It appears like a sponge."
- This is not a characteristic of softwood. Softwood does not have a spongy appearance.
- **Option (c)**: "It can be bent easily."
- This is also not a defining characteristic of softwood. The flexibility of wood can vary and is not the reason for the classification.
- **Option (d)**: "It does not possess vessels."
- This is the correct answer. Gymnosperms lack thick-walled vessels in their xylem, which contributes to the classification of their wood as softwood.

3. **Conclusion**: The wood of gymnosperms is known as softwood primarily because it does not possess vessels, which are essential for providing strength to the wood. Therefore, the correct answer is **(d) It does not possess vessels**.
