megasporangium

Example:The female gametophyte, containing the megasporangium, is crucial for the formation of new plants through sexual reproduction.

Definition:The female reproductive organ in seed plants that contains the megasporangium and gives rise to the megagametophyte and subsequently the egg cell.

Example:The process of megaspore formation within the megasporangium initiates the development of female gametophytes, essential for sexual reproduction.

Definition:In some plant species, including seed plants, megaspores are produced by the megasporangium and develop into female gametophytes, which produce eggs within the ovule.

Example:From the megasporangium, megaspores develop into megagametophytes, which then produce an egg that can be fertilized by sperm.

Definition:The female gametophyte that develops from a megaspore, providing the egg cell necessary for fertilization in plants that have a double fertilization process.
