Introduction:

The life cycle of angiosperm plant undergoes alternation of generations with multicellular diploid and haploid stages. The sporophyte is the diploid generation which produces spores by meiosis. Each spore divides mitotically to produce a multicellular haploid gametophyte, which undergoes mitosis to generate haploid gametes-egg cells or sperm cells. These gametes fuse at the event of fertilization.
