Where is the meristematic zone located in a plant root?

The meristematic zone in a plant root is located at the tip of the root. This region is critical for the growth of the plant, as it contains actively dividing cells or meristematic cells. These cells are responsible for the primary growth of the root, enabling it to elongate and penetrate deeper into the soil. The meristematic zone contributes to the formation of new root cells that will differentiate into various specialized cells necessary for functions such as absorption and support.

In contrast, other areas of the root, such as the middle or base, contain more mature cells that have already undergone differentiation. These differentiated cells are involved in specific functions like nutrient uptake or structural support, rather than in the active division seen in the meristematic zone. As a result, the meristematic zone is crucial for maintaining root growth and overall plant health.
