In dicotyledonous stems, what is present between phloem and xylem?

Options

  1. ACambium
  2. BSecondary xylem
  3. CSecondary phloem
  4. DClosed vascular bundles

Correct answer

A. Cambium

Step-by-step solution

The vascular system consists of complex tissues,the phloem and the xylem.The xylem andphloem together constitute vascular bundles. In dicotyledonous stems, cambium is present between phloem and xylem. Such vascular bundles because of the presence of cambium possess the ability to form secondary xylem and phloem tissues, and hence are called open vascular bundles. In the monocotyledons, the vascular bundles have no cambium present in them. Hence, since they do not form secondary tissues they are referred to as close
