What is the name of the layer of meristematic cells located between the phloem and the xylem?

The layer of meristematic cells located between the phloem and the xylem is known as the cambium. This tissue plays a crucial role in the secondary growth of plants, contributing to the increase in diameter of stems and roots. The cambium is responsible for producing new phloem cells on the outside and new xylem cells on the inside, allowing for the plant to grow thicker over time.

Understanding the function of cambium is essential for tree care and maintenance because it is vital for the health and vitality of the plant. The growth produced by the cambium allows trees to transport nutrients and water efficiently, making it fundamental in the development of the tree’s overall structure and function.

Other options do not align with this specific role: cladodes are flattened stems that perform photosynthesis, periderm refers to the protective outer layer of bark, and parenchyma cells are versatile cells involved in various functions, including storage and tissue repair but do not have the specific position or function in growth that cambium does.
