Which is a character of gymnospermous wood

Options

A. Porous
B. Diffused porous
C. Ring porous
D. Non-porous.

Answer

### Step-by-Step Solution:

1. **Understanding Gymnosperms**: Gymnosperms are a group of seed-producing plants that include conifers. They are characterized by having seeds that are not enclosed in an ovary (fruit).

2. **Analyzing Wood Structure**: The wood of gymnosperms is primarily composed of xylem, which is responsible for water transport. Unlike angiosperms (flowering plants), gymnosperms do not have vessels in their xylem.

3. **Identifying Wood Types**: In the context of wood, there are different types based on the presence of vessels:
- **Porous Wood**: This type of wood contains vessels and is typically found in angiosperms.
- **Non-Porous Wood**: This type of wood lacks vessels, which is characteristic of gymnosperms.

4. **Conclusion on Gymnosperm Wood**: Since gymnosperms do not contain vessels, their wood is classified as non-porous. Additionally, gymnosperm wood is often referred to as softwood due to the presence of tracheids, which are less thick-walled compared to the vessels found in angiosperms.

5. **Final Answer**: The correct character of gymnospermous wood is that it is **non-porous**.
