Answer:
They essentially first start with a small organism. This organism is then transferred to a host, usually transferred from eating/touching something. Then, the host gets infected with said virus.
The host will then pass on the organism by sneezing, coughing, and/or touching them. This continues on, usually until a cure is found. It can still have the ability to transfer, generally from people who don't get the cure.

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.

The gases diffuse between the cells spaces of the leaf through pores, which are normally on the underside of the leaf - stomata. From these spaces they will diffuse into the cells that require them.
