Where is the area of cell division located on a root?

The area of cell division in a root is located at the root tip. This region, known as the meristem, is responsible for the growth of the root. The meristematic cells found here are actively dividing and producing new cells, which contribute to the elongation and development of the root. This area is essential for the overall growth of the plant, as it allows for the exploration of soil and increases the plant's ability to uptake water and nutrients.

In contrast, the root cap is a protective structure that covers the tip of the root, helping to shield the delicate meristematic tissue from damage as it pushes through the soil. Root hairs are extensions of root epidermal cells that serve to increase surface area for absorption but do not play a role in cell division. Root nodes are points along the stem where leaves or branches originate, and they do not pertain to root growth and cell division. Thus, the root tip is unequivocally recognized as the site of active cell division in the root system.
