In woody dicotyledons, the arrangement of vessels is either diffuse porous or ring porous. Based on the these data, which one of the following statements is correct ?
- A
Ring porous vessels are specialised 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
