검증된 단계별 안내1
Understand the life cycle of angiosperms, which includes alternation of generations between the sporophyte and gametophyte stages.
Recognize that the female gametophyte generation in angiosperms is responsible for producing the egg cells necessary for fertilization.
Identify the structures involved in the female reproductive system of angiosperms: the ovule, embryo sac, and seed coat.
Learn that the embryo sac is the structure within the ovule where the female gametophyte develops and contains the egg cell.
Differentiate between the embryo sac and other structures: the pollen grain is the male gametophyte, the ovule contains the embryo sac, and the seed coat is part of the seed structure, not the gametophyte.
