Two intermediates of the sterol biosynthesis pathway, isopentenyl diphosphate and dimethylallyl diphosphate, are used by archaea in the biosynthesis of isoprenoids. Isoprenoids are organic compounds <span> which play widely varying roles in the physiological processes of plants and animals.</span>

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
