Final answer:
The development of a female gametophyte from one surviving megaspore after a meiotic division in the ovule is true.
Step-by-step explanation:
The statement that a female gametophyte develops from one megaspore in the ovule is true. In the process of megasporogenesis, out of four megaspores produced by the meiotic division of a single megaspore mother cell, only one megaspore survives. This surviving megaspore undergoes mitotic divisions to form an eight-nucleate, seven-cell female gametophyte, also known as the megagametophyte or embryo sac. During this development, which takes place within the megasporangium tissue found in the ovary, the formation of the female gamete or egg occurs, leading eventually to fertilization and seed development.
