Detailed explanation-1: -To make them flower and produce seeds, they involve bees and/or male and female plants. Seed-bearing plants differ from all other plants in that their gametes do not need water for fertilisation, or mature cells that need germination with another mature haploid male or female.
Detailed explanation-2: -The differences are the following: The seedless plants produces plants via asexual reproduction, and seed-bearing plants produce plants via sexual reproduction. The seedless plants do not have seed, but seed-bearing plants do. The seedless plants produces spores, and seed-bearing plants produce seeds.
Detailed explanation-3: -Gymnosperms do not require water for fertilization. In gymnosperms, two types of spores are produced, so the haploid stage can start as either a male or female spore.
Detailed explanation-4: -Water is not required for the movement of male gametes in seed plants.
