<span>"Water stress" is when the demand of water exceeds its supplies. Factors that increase water stress include increased population, pollution of existing water sources and periods of drought. Ways to combat water stress may be proper distribution of water, establishment of sanitation facilities and prevention of pollution of water sources.</span>
Mitosis is a division of a single cell into two identical daughter cells. It consists of four phases: prophase, metaphase, anaphase and telophase and cytokinesis. During metaphase, sister chromatids join together in the middle of the cell, so that during anaphase they can separate from each other to the opposite sides of the cells where they will represent future "nucleus" of the daughter cells. However, is metaphase was skipped, sister chromatids would not join in the middle, and consequently, they would not separate in anaphase. One of the possible consequences is that mitosis will stop and the cell would not divide. On the other hand, it could lead to unequal distribution of chromatids, so one cell will get both copies of chromosomes and the other will lack in chromosomes, which is lethal in both situations.
During telophase, membrane-enclosed vesicles derived from the Golgi apparatus migrate to the center of the cell where the metaphase plate used to be and fuse to form a cell plate. Eventually, the growing cell plate fuses with the existing plasma membrane, producing two daughter cells, each with its own plasma membrane.
