Alternation of Generations
The alternation of Generations is the general life cycle that all plant (multicellular autotrophs) are going to follow. Starting from fertilization, two gametes (each are 1n) are going to meet up and fertilize. The zygote (2N) will grow from mitosis until it is a sporophyte (2n). The sporophyte is going to undergo meiosis, creating spores (1n). The spore is going undergo mitosis until it is a gametophyte (1n). The gametophyte will also undergo mitosis and produce gametes (1n).
