In woody dicotyledons, the arrangement of vessels is either duffuse porous or ring porous. Bases on these data, which one of the following statement is correct

Options

A. Ring porous vessels are specialized and are used for conducting more water for a shorter period only, when tyloses occur early in the vessels
B. Although diffuse porous vessels are not so specialized as ring porous vessels, they conduct more water at all periods and through new xylem vessels added gradually during development
C. Diffuse porous vessels carry more water and also faster because of a greater number of small vessels having greater capillary force
D. Ring porous vessels conduct more water as they are formed early during development, when the need for water is great

Answer

D

Explanation

In diffuse porous the vessels are more or less equal in diameter. The vessels are shorter in length the those of ring porous wood. The rate of transport of water in plants with diffuse porous wood is slower than those with ring porous. The development of vessel in diffuse porous is usually slow.
