Describe the structure and development of male and female gametophytes.

Key Differences Between Male and Female Gametophytes

Feature Male Gametophyte (Pollen Grain) Female Gametophyte (Embryo Sac)
Location Anther (microsporangium) Ovule (megasporangium)
Development Microsporogenesis & Microgametogenesis Megasporogenesis & Megagametogenesis
Number of Cells Typically 2-3 cells (vegetative and generative cells) 7 cells, 8 nuclei
Gametes Produced Two sperm cells One egg cell
Role in Fertilization Delivers sperm cells to the ovule Houses the egg cell for fertilization

Conclusion

The male gametophyte (pollen grain) and female gametophyte (embryo sac) follow distinct developmental pathways, but both contribute to the reproductive process in seed plants. The pollen grain ensures sperm delivery, while the embryo sac nurtures the fertilized zygote and initiates seed formation.
