What is the cambium composed of?

• A. Xylem and Phloem
• B. Roots and Shoots
• C. Leaves and Stipules
• D. Bark and Pith

Answer: (A)

The cambium is a layer of actively dividing cells found in the vascular tissue of plants, specifically responsible for secondary growth. It is located between the xylem (which transports water and minerals) and the phloem (which transports nutrients and food) within the plant's stem and roots. This tissue plays a crucial role in increasing the thickness of stems and roots, contributing to the overall girth of the plant. The correct answer, which indicates that cambium is composed of xylem and phloem, reflects its function in facilitating the growth and development of these two essential vascular components. As the cambium divides, it produces new xylem cells towards the inside and new phloem cells towards the outside, thereby enabling the plant to expand and transport resources efficiently. Other choices do not accurately represent the composition or function of cambium. Roots and shoots refer to different parts of the plant; leaves and stipules are associated with foliage but do not relate to cambial composition; bark is made up of layers including phloem but does not include cambium itself, and pith is the central part of the stem made up of parenchyma cells, distinct from the cambium.
