∙ 11y agoIt is the area of primary root growth where cells differentiate.
This is the organization of roots from the base closest to the plant itself to the tip of the root: zone of maturation - cells specialize to carry particular functions (root hairs present) zone of elongation - rows of newly produced cells elongate zone of cell division - new cells being produced root cap - covers the growing tip
maturation
The thymus gland, it promotes the maturation of T-cells.

The thymus produces thymosin, which promotes the maturation of t cells.
One grows faster than the other alowing them to mature faster and quicker than a normal seed would in another environment
The zone of elongation occurs when the cells in this zone stretch and lengthen as small vacuoles within the cytoplasm coalesce and fill with water. One or two large vacuoles occupy almost all of the cell volume in fully elongated cells. Cellular expansion in this zone is responsible for pushing the root cap and apical tip forward through the soil.

On average girls are more mature when they turn 10. Boys become more mature when they are maybe 13.
