- The gymnosperm life cycle involves alternation of generations, with a sexual phase (gametophyte generation) and an asexual phase (sporophyte generation)12. Key points include:
- Gamete production occurs in the sexual phase.
- Spores are produced in the asexual phase.
- Gymnosperms have a sporophyte-dominant cycle.
- Reproductive organs are usually cones.

This type of life cycle is known as alternation of generations. Gamete production occurs in the sexual phase or gametophyte generation of the cycle. Spores are produced in the asexual phase or sporophyte generation.www.thoughtco.com/what-are-gymnosperms-4164…The life cycle of gymnosperms is both haploid and diploid, i.e., they reproduce through the alternation of generations. They have a sporophyte-dominant cycle. The gametophyte phase is relatively short. The reproductive organs are usually cones.byjus.com/biology/gymnosperms/ - People also ask

- Upon landing on the female cone, the tube cell of the pollen forms the pollen tube, through which the generative cell migrates towards the female gametophyte through the micropyle. It takes approximately one year for the pollen tube to grow and migrate towards the female gametophyte. The male gametophyte containing the generative cell splits into t...
