AP BIOLOGY

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: -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-4: -The apical meristem, just beneath the root cap, contains most of the root’s dividing cells. Therefore, cells in this area must complete the cell cycle often.
