The Life Cycle Of A Plant: Conclusion
Main Points:

Content: When a male reproductive cell ( sperm) produced by a gametophyte fuses with a female reproductive cell ( egg) produced by a gametophyte of the same species, the result is a diploid cell called a zygote. This zygote develops and grows via mitosis into a sporophyte, thereby completing the plant’s life cycle. Moss (Leucolepis acanthoneuron) in its gametophyte phase (the dominant phase in the life cycle of bryophytes). One Generation Reduced In Size
In many plant groups, the members of one generation are reduced in size (often to just a few cells) and, rather than growing independently, develop inside the bodies of members of the other generation. For example, the gametophytes of angiosperms (flowering plants) and gymnosperms (plants such as conifers) are much reduced in size, comprising of just a few cells. In these plant groups, the male gametophyte is carried by pollen and develops within the stigma of a sporophyte, while the female gametophyte develops within the ovule (the egg-producing organ) of a sporophyte. The angiosperm and gymnosperm plants that we see around us are in their sporophyte phase. In bryophytes such as moss, the gametophyte stage is phase is the dominant phase. Self-Fertilization
Many species of plants produce individuals with both male and female parts. This can result in self-fertilization, which occurs when a plant’s sperm fertilizes its own eggs.
