Apical meristem is a region of actively dividing cells at the tips of roots and shoots in plants. It is responsible for primary growth, allowing the plant to increase in length.
Lateral Meristem: A region of cell division that contributes to the thickness or girth of the plant body, responsible for secondary growth.
Auxin: A plant hormone that regulates growth, particularly influencing cell elongation near the apical meristem.
Differentiation: The process by which unspecialized cells from the meristem develop into specialized tissues with specific functions.
