Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The cambuim is a section of cells in a plant that can become either part of the xylem or phloem, depending on the growth and needs of the plant. If the cambium of a particular plant was damaged, what would be the most likely effect on the plant?
A
The plant would lose its ability to carry out photosynthesis.
B
the plant would have uncontrolled growth.
C
The plant would not experience any change in physiology.
D
The plant would not be able to transport nutrients and water.
Explanation: 

Detailed explanation-1: -The cambuim is a section of cells in a plant that can become either part of the xylem or phloem, depending on the growth and needs of the plant. If the cambium of a particular plant was damaged, what would be the most likely effect on the plant? A. The plant would lose its ability to carry out photosynthesis.

Detailed explanation-2: -The structure of plant roots, stems, and leaves facilitates the transport of water, nutrients, and photosynthates throughout the plant. The phloem and xylem are the main tissues responsible for this movement.

Detailed explanation-3: -The cambium is defined as the actively dividing layer of cells that lies between, and gives rise to the secondary xylem and phloem. From: Secondary Xylem Biology, 2016.

Detailed explanation-4: -(Recall that xylem is located toward the interior and phloem toward the exterior of the bundle.) The cells of the vascular cambium divide and form secondary xylem (tracheids and vessel elements) to the inside, and secondary phloem (sieve elements and companion cells) to the outside.

Detailed explanation-5: -Cambium refers to the slender plant membrane located right underneath the bark of a woody tree or plant. The cambium has several functions. In woody plants, it produces layers of xylem and phloem, consequently enhancing the stem’s diameter. It also encourages the secondary growth of roots and stems.
