Detailed explanation-1: -These regions of active cell division in plants are found in the growing tips of roots and stems, and they are called apical meristems.
Detailed explanation-2: -Meristem is a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate. Apical meristems are found at the apex, or tip, of roots and buds, allowing roots and stems to grow in length and leaves and flowers to differentiate.
Detailed explanation-3: -Cell division occurs in the apical meristem.
Detailed explanation-4: -Abstract. Plant cells divide in two by constructing a new cell wall (cell plate) between daughter nuclei after mitosis. Golgi-derived vesicles are transported to the equator of a cytoskeletal structure called a phragmoplast, where they fuse together to form the cell plate.
Detailed explanation-5: -The root cap is a type of tissue at the tip of a plant root. It is also called calyptra. Root caps contain statocytes which are involved in gravity perception in plants. If the cap is carefully removed the root will grow randomly.
