Gymnosperms, like all vascular plants, have a sporophyte-dominant life cycle, which means they spend most of their life cycle with diploid cells, while the gametophyte (gamete-bearing phase) is relatively short-lived. Like all seed plants, they are heterosporous, having two spore types, microspores ...

The life cycle of a gymnosperm involves alternation of generations, with a dominant sporophyte in which reduced male and female gametophytes reside. The adult, or sporophyte, phase is the main phase in an angiosperm's life cycle. Like gymnosperms, angiosperms are heterosporous. They produce microspores, which develop into pollen grains (the male gametophytes), and megaspores, which form an ovule containing the female gametophytes. Part I Gymnosperm Life Cycle Diagram.

Embryo sacs (megagametophytes) develop in the ovules, which are found in the ovary. Pollen grains (microgametophytes) develop in the pollen sacs (microsporangia) of the anther.

Difference between Angiosperms and Gymnosperms. Following are the important difference between angiosperms and gymnosperms: Angiosperms. Gymnosperms. A seed is produced by flowering plants and is enclosed within an ovary. A seed is produced by non-flowering plants and are unenclosed or naked. The lifecycle of these plants are seasonal.

In the life cycle of a conifer, the sporophyte (2n) phase is the longest phase. The gametophytes (1n), microspores and megaspores, are reduced in size. This phase may take more than one year between pollination and fertilization while the pollen tube grows towards the megasporocyte (2n), which undergoes meiosis into megaspores.

Pine Tree Life Cycle (Gymnosperm) Pine trees are in a group of plants called Gymnosperms. This means " naked seed ." That is because, unlike a flowering plant, the seeds of pine trees are not inside a protective, fleshy fruit. Think of how an apple protects its seeds inside its fleshy body. A gymnosperm does not have that.
