Question

Diffuse porous woods are characteristic of plants growing in ________________.

• A. Alpine region
• B. Cold winter regions
• C. Temperate climate
• D. Tropical

Answer 1

The correct option is D Tropical

In most of the gymnosperms such as conifers and cycads. Vessels are not present and the wood is made entirely of tracheids. These woods are known as nonporous. In angiosperms, the wood consists of both tracheids and vessels. The wide vessels are appearing with pores between. Such wood is called porous.

In these porous woods, if vessels have essentially equal diameters the wood is known as diffuse-porous. It is the characteristic of plants growing in tropical regions.

So, the correct option is D.
