Question

In wood dicotyledons, the arrangement of vessels is either diffuse porous or ring porous or ring porous. Based on these data, which one of the following statements is correct?

Choices

Choice (4) Response

Ring porous vessels conduct more water as they are formed early during development, when the need for water is great.

b.

Ring porous vessels are specialized and are used for conducting more water for a shorter period only, when tyloses occur early in the vessels.

d.

Diffuse porous vessels carry more water and also faster because of a greater number of small vessels having greater capillary force.
