Final answer:
In the region of maturation in growing roots, cells are differentiating into specific cell types to carry out specialized functions.
Step-by-step explanation:
In growing roots, cells in the region of maturation are differentiating into specific cell types. The region of maturation is the part of the root tip where the root cells begin to differentiate into specialized cell types. This zone is located just behind the zone of elongation, and it marks the transition from elongation to maturation.
For example, in the root cap, the cells may differentiate into specialized cells called columella cells, which are responsible for gravity detection. In the cortex, the cells may differentiate into parenchyma cells, which store food and water. And in the vascular tissue, the cells may differentiate into xylem and phloem cells, which transport water and nutrients throughout the plant.
Therefore, in the region of maturation in growing roots, cells are differentiating into specific cell types to carry out specialized functions.
