merisztimból
Merisztimból is a term used in some botanical contexts, although it is not a widely recognized or standardized scientific term. It appears to refer to the tip of a plant's root or shoot that contains actively dividing cells, a region known more commonly as the meristem. Specifically, "merisztimból" might be a colloquial or regional variation to describe the apical meristem. These meristems are responsible for primary growth in plants, leading to an increase in length. The cells within the meristem are undifferentiated and undergo rapid cell division through mitosis, providing new cells that will eventually differentiate into various plant tissues such as epidermis, ground tissue, and vascular tissue. The root apical meristem is located at the tip of the root and is protected by a root cap, which shields it as the root grows through the soil. The shoot apical meristem is found at the tip of the stem and is responsible for the development of leaves, flowers, and stem elongation. While the exact origin and widespread usage of the term "merisztimból" are unclear, its likely meaning relates to these critical growth points in plants.
