Question

Quizplus · Accepted Answer

As the oak tree ages, it undergoes secondary growth, which is the thickening of the trunk due to the growth of woody tissue called secondary xylem and secondary phloem. Primary growth occurs during the tree's early development, while tertiary growth and meristem refer to more specific types of growth. Differentiated cells refer to cells that have undergone specialization into a specific cell type.
