NEET BIOLOGY

Detailed explanation-1: -In cell biology, mitosis (/maɪˈtoʊsɪs/) is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division by mitosis gives rise to genetically identical cells in which the total number of chromosomes is maintained. Therefore, mitosis is also known as equational division.

Detailed explanation-2: -Meristems are regions in plants in which mitosis takes place. Apical meristems are at the tips of shoots and roots and contribute to increases in length. Lateral meristems are responsible for increases in girth.

Detailed explanation-3: -Cells in the zone of cell division prepare for mitosis during interphase by replicating DNA and organelles. During the end of mitosis the cell begins to divide in two.

Detailed explanation-4: -ZONE OF CELL DIVISION: Includes the apical meristem, which is a group of cells specialized for the production of new cells, located at the farthest point of the tissue or the organ produced (found in both shoots and roots). Very different from animal growth!
