- Seed producing plants
Seeds serve as structure for propagation and contains an embryo that is usually nourished and protected by the seed coat. The embryo results from fertilization of the ovule by the pollen grain, a process that takes place after pollination. The entire process is independent of water.
Seedless plants produce spores instead. These spores can be sexual or asexual. Sexual reproduction in seedless plants requires that the male gametes (sperms) swim to meet the female gametes (egg). Consequently, water is necessary for the motile male gametes and that is why most seedless plants grow is aquatic or moist areas.
