What are the structural characteristics of
(i) Meristematic cells near root tip? (ii) The cells in the elongation zone of the root?
i) Meristematic cells near root tip are in the process of active divisions, i.e., mitosis divisions. Each chromosome is split lengthwise into two homologous chromatids, which pass equally into daughter cells taken place.
(ii) The cells in the elongation zone of the root have enlarge size due to vacuolation, i.e., by absorption of water. In these a large central vacuole is present, which push the cytoplasm to a thin boundary layer against the cell wall. The daughter cells formed after divisions have half the size of the parent cell.
