Tree cell division occurs in which tissue type?

• A. Meristems
• B. Cambium
• C. Xylem
• D. Phloem

Answer: (A)

Cell division happens in meristematic tissue. Meristems are the regions where cells remain undifferentiated and actively divide to supply new cells for growth. In trees, growth in length comes from apical meristems at the tips of roots and shoots, while growth in girth involves lateral meristems such as the vascular cambium and cork cambium. Mature xylem and phloem are differentiated, non-dividing tissues, produced by these meristematic regions. The vascular cambium, though a specific type of meristem, reinforces that the general tissue type responsible for division is meristematic tissue.
