Detailed explanation-1: -During mitotic progression, typically after the anaphase onset, the cell may undergo cytokinesis. In animal cells, a cell membrane pinches inward between the two developing nuclei to produce two new cells. In plant cells, a cell plate forms between the two nuclei.

Detailed explanation-2: -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-3: -Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.

Detailed explanation-4: -All eukaryotic organisms-including aquatic plants and algae-grow through the process of mitosis. Mitosis is a process where one cell divides into two cells (Fig. 2.46). Chromosomes in the original cell are duplicated to ensure that the two new cells have full copies of the necessary genetic information.

Detailed explanation-5: -Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies-or ‘replicates’-its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
