Background of Mitosis
Mitosis is the process that allows plant cells to copy their genetic material and pass it to new daughter cells. Leading up to mitosis is a stage called interphase. Interphase is simply a cell's "resting zone" in which in prepares the process for division. For example, it has three stages called G1, S, and G2.
The most important things that happen in interphase are that the plant cell enlarges to get ready for division and the chromosomes become replicated to begin the next phase.
Starting mitosis is the first stage called prophase. Prophase allows the chromatids (future chromosomes) to start breaking away and allows other organelles (such as the nuclear membrane) to dissolve and start the division process. Next is metaphase, in which the chromatid turned chromosomes line up across the equator of the cell forming a metaphase plate.
Following this is anaphase, in which a plant cell's spindles drag the chromosomes to opposite ends of the cell. This is important because it allows the genetic material to be passed to the new daughter cell while also keeping genetic material for the parent cell.
The last phase is called telophase. Telophase is almost the opposite of prophase, in which the chromosomes begin to revert back into chromatids and the nuclear envelope begins to redevelop. It is here where plant cell cytokinesis takes place that further divides the cell into two.
