Summary In gymnosperms, the gametophyte generation takes place in a cone, which forms on the mature sporophyte plant. Each male gametophyte is just a few cells inside a grain of pollen. Each female gametophyte produces an egg inside an ovule. Pollination must occur for fertilization to take place.

In Summary: Gymnosperms. Gymnosperms are heterosporous seed plants that produce naked seeds. They appeared in the Paleozoic period and were the dominant plant life during the Mesozoic. Modern-day gymnosperms belong to four phyla. The largest phylum, Coniferophyta, is represented by conifers, the predominant plants at high altitude and latitude.

The seed that is formed contains three generations of tissues: the seed coat that originates from the sporophyte tissue, the gametophyte that will provide nutrients, and the embryo itself. Figure 26.2. 1 illustrates the life cycle of a conifer. The sporophyte (2 n) phase is the longest phase in the life of a gymnosperm.

Explain The Life Cycle Of Gymnosperms In Detail
The earliest reliable record of gymnosperms dates their appearance to the Carboniferous period (359-299 million years ago). Gymnosperms were preceded by the progymnosperms (“first naked seed plants”). The life cycle of a gymnosperm involves alternation of generations, with a dominant sporophyte in which reduced male and female gametophytes reside. All gymnosperms are heterosporous. The male and female reproductive organs can form in cones or strobili.

According to the “anthophyte” hypothesis, the angiosperms are a sister group of one group of gymnosperms (the Gnetales), which makes the gymnosperms a paraphyletic group.
