Megasporangium  tissue gives rise to the female gametophyte.
<h3>What is the name of the diploid tissue that gives rise to the female gametophyte?</h3>
- Three of the four haploid megaspores worsen into antipodal cells interior the female gametophyte. 
- The central cell of the female gametophyte contains two cores that when fertilized gotten to be the endosperm.
- Megasporogenesis alludes to the advancement of megaspores from the megasporocyte, the cell that experiences meiosis. 
- Meiosis of the megasporocyte core comes about within the arrangement of four haploid megaspore cores. 
- In most taxa, meiosis is taken after by cytokinesis, coming about in four megaspore cells. 
- This design is named monosporic megasporogene - sis; since of the four megaspores delivered, as it were one of them contributes to the female gametophyte
