Out of diffuse porous and ring porous woods, which is correct ?

Options

A. Ring porous wood , carries more water for short period
B. Diffuse porous wood carries more water
C. Ring porous wood carries more water when need is higher
D. Diffuse porous wood is less specialised but conducts water rapidly through out

Explanation

### Step-by-Step Solution:

1. **Understanding Wood Types**:
- Wood can be classified into two main categories: non-porous and porous.
- Non-porous wood is typically found in gymnosperms (like conifers) and is made entirely of tracheids, lacking vessels.

2. **Defining Porous Wood**:
- Porous wood is found in angiosperms and contains both tracheids and vessels.
- The vessels appear as pores and can be categorized into two types: diffuse porous and ring porous.

3. **Characteristics of Diffuse Porous Wood**:
- In diffuse porous wood, vessels have similar diameters and are uniformly distributed throughout the growth ring.
- This type of wood is typically found in tropical plants and is less efficient in water conduction.

4. **Characteristics of Ring Porous Wood**:
- In ring porous wood, the vessels in the early wood are larger than those in the late wood of the same growth ring.
- This structure allows for more efficient water transport, especially during periods of high water demand.

5. **Evaluating the Statements**:
- **Statement 1**: "Ring porous wood carries more water for a short period." - This is incorrect; it can carry water for longer periods as needed.
- **Statement 2**: "Diffuse porous wood carries more water." - This is incorrect; it is less efficient and carries less water.
- **Statement 3**: "Ring porous wood carries more water when need is higher." - This is correct; it is designed for efficient water transport during high demand.
- **Statement 4**: "Diffuse porous wood is less specialized but conducts water rapidly throughout." - This is incorrect; it is less efficient.

6. **Conclusion**:
- The correct statement is that "ring porous wood carries more water when the need is higher."
