Which part of the root contains the apical meristem?

The part of the root that contains the apical meristem is the region of cell division. The apical meristem is a zone of actively dividing cells located at the tip of roots (and shoots) and is crucial for the growth of these structures. It generates new cells that will differentiate into various root tissues. The surrounding tissues that arise from these divisions are responsible for the root's growth in length.

The region of cell division is specifically identified as the area where new cells are produced. This zone is characterized by small, densely packed cells that are in various stages of division. In contrast, the region of elongation is where the newly formed cells grow and expand, contributing to the overall increase in root length, while the region of maturation is where cells undergo differentiation to take on specific functions.

Similarly, the root cap serves a different purpose; it protects the apical meristem as the root pushes through the soil. This distinction is important as each region of the root has specific roles that contribute to the overall function and health of the plant. Understanding the role of the apical meristem and its location helps in grasping fundamental concepts of plant growth and development.
