Give information about the reproductive organs of Gymnosperms.

(N/A) Gymnosperms are heterosporous,meaning they produce two types of spores: microspores and megaspores.
$1$. These spores are produced within sporangia that are borne on sporophylls.
$2$. Sporophylls are arranged spirally along an axis to form lax or compact strobili or cones.
$3$. The strobili bearing microsporophylls and microsporangia are called male strobili or male cones.
$4$. The strobili bearing megasporophylls with ovules or megasporangia are called female strobili or female cones.
$5$. The male gametophyte is highly reduced and is confined to a limited number of cells,known as pollen grains.
$6$. The female gametophyte is also reduced and is retained within the megasporangium (ovule).
