The reduction of the female gametophyte to only a few cells (the embryo sac) is the final stage of seed evolution in:
Show answer and explanation
Correct answer: Angiosperms
Angiosperms represent the peak of gametophyte reduction, where the female gametophyte is typically reduced to a 7-celled, 8-nucleate structure. This extreme reduction increases the speed and efficiency of the reproductive cycle.
