What is the female gametophyte in a pine tree?

The female and male inflorescence of the pine tree develop as cones on the sporophyte.

They have both male and female cones, with the female cones bearing seeds. The seeds lie in the open, wedged between the cone’s scales. Pine cones take two years to grow, become fertilized and produce seeds, and it’s a complicated story.One may also ask, what are the names given to the male and female gametophytes for pine trees? Once a pine tree reaches sexual maturity, it grows separate male and female reproductive parts called strobili (singular: strobilus). The male strobilus grows pollen and releases it into the wind where it lands on the female strobili of neighboring trees to create new pine seeds. Simply so, is a pine tree a Sporophyte or Gametophyte? Pine trees are conifers (cone bearing) and carry both male and female sporophylls on the same mature sporophyte. Therefore, they are monoecious plants. Like all gymnosperms, pines are heterosporous, generating two different types of spores: male microspores and female megaspores.What is the female gametophyte?The female gametophyte is also commonly called the embryo sac or megagametophyte. The male gametophyte, also called the pollen grain or microgametophyte, develops within the anther and consists of two sperm cells encased within a vegetative cell (Gifford and Foster, 1989).
