Detailed explanation-1: -Seeds and pollen allowed plants to reproduce in absence of water.
Detailed explanation-2: -Q: What adaptations allow seed plants to reproduce without open water? A: Adaptations include 1)a reproductive process that takes place in cones or flowers, 2)the transfer of sperm by pollination, and 3)the protection of embryos in seeds.
Detailed explanation-3: -Pollen allows angiosperms and gymnosperms to reproduce away from water, unlike mosses and ferns which require water for sperm to swim to the female gametophyte.
Detailed explanation-4: -Some plants, like ferns and mosses, grow from spores. Other plants use asexual vegetative reproduction and grow new plants from rhizomes or tubers. We can also use techniques like grafting or take cuttings to make new plants.
