Detailed explanation-1: -Seeds and Pollen as an Evolutionary Adaptation to Dry Land Storage tissue to sustain growth and a protective coat give seeds their superior evolutionary advantage. Several layers of hardened tissue prevent desiccation, and free reproduction from the need for a constant supply 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. Seed=a plant embryo and a food supply, encased in a protective covering.

Detailed explanation-3: -Vascular Plants Evolve. Plants evolved a number of adaptations that helped them cope with these problems on dry land. One of the earliest and most important was the evolution of vascular tissues. Vascular tissues form a plant’s “plumbing system.” They carry water and minerals from soil to leaves for photosynthesis.

Detailed explanation-4: -Plants have evolved several adaptations to life on land, including embryo retention, stomata, and vascular tissue.
