PRIMORDEAL seas absorbed GASES of the atmosphere,There  was a heavy concentration of ultraviolet radiation from the sun, and frequent LIGHTNING strikes, and the environment was helpful in producing ORGANIC molecules from INORGANIC  molecules.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
