What is the region at the tip of the root made up of meristematic tissue called?

The region at the tip of the root that is made up of meristematic tissue is known as the meristematic region. This area is crucial for root growth, as it contains actively dividing cells that contribute to the formation of new root tissue. These meristematic cells are undifferentiated and retain the ability to divide, allowing for the continuous growth of the root as it extends into the soil to absorb water and nutrients.

In contrast, the elongation region refers to the area just above the meristematic region, where cells lengthen and contribute to the increase in root length. The maturation region, located further up from the elongation zone, is where cells begin to differentiate into specialized cell types and lose their capacity to divide. Primary tissue comprises the fundamental types of cells in plants that arise from the meristematic tissue, but it does not specifically denote the actively dividing area at the tip of the root. Thus, the correct designation for this actively growing section is the meristematic region.
