B

C

D

Answer

Gymnosperms are group of seed plants that do not produce flowers. However, like all vascular plants they have a sporophyte-dominant life cycle and the relatively short-lived gametophytic phase. While the
microspores and megaspores, are typically produced in pollen cones or ovulate cones, Gametophytes develop within the spore wall. Pollen grains (microgametophytes),mature from microspores, and produces sperm cells. Megagametophytes develop from megaspores and are retained within the
ovule. They typically produce multiple archegonia. Thus they follow two sporophytic and one gametophytic generation.
