Question

Where is the vascular cambium located in an established woody plant?

a) Between xylem and phloem
b) In the epidermis
c) At the tip of the stem
d) Surrounding the stomata

Answer 1

The vascular cambium is found between xylem and phloem in woody plants, contributing to secondary growth by increasing the girth of stems and roots.

Step-by-step explanation:

The vascular cambium is located between xylem and phloem in an established woody plant. It is a type of secondary meristem and plays a crucial role in the process of secondary growth, which is responsible for the increase in thickness or girth of the plant stem or root. As part of this growth, the vascular cambium forms a continuous ring of meristematic (embryonic) cells from undifferentiated cells produced by apical meristems. This ring is situated between the primary xylem and phloem, wherein cell divisions of the vascular cambium produce secondary xylem on the inside and secondary phloem on the outside as the plant grows.
