Diffuse porous woods are characteristic of plants growing in:
Correct answer: D. Tropics
- A. Alpine region
- B. Cold winter regions
- C. Temperature climate
- D. Tropics
Explanation
In most of the gymnosperms, like conifers and cycads, vessels are absent and the wood is made entirely of trach eids. Such wood is known as nonporous. In angiosperms, on the other hand, the wood consists of both tracheids and vessels. The wide vessels appear as pores between otherwise small-sized tracheary elements. Such a wood is known as porous. In porous wood, if vessels have essentially equal diameters and are uniformly distributed throughout the ring, the wood is known as diffuse-porous. It is characteristic of plants growing in the tropics.
