Explanation:
Detailed explanation-1: -In a pine, the sporophyte is a tree, whereas the gametophytes are very tiny and strictly unisexual (male or female). The male (sperm-producing) gametophyte is the pollen grain, whereas the female (egg-producing) gametophyte is found in the immature seed (called an ovule).
Detailed explanation-2: -The microspores give rise to male gametophyte after germination while the macrospores germinate to form female gametophyte. So, the female gametophyte is retained on the parent sporophyte in heterosporous species of pteridophytes.
