Some notable adaptations include the stem (which is becomes woody in trees), leaves, and roots. These two characteristics allowed some gymnosperms and angiosperms to fully adapt to land conditions. This gave way to spores, seeds and fruits for dispersal and pollen for fertilization. 3. Plants with vascular tissue do not appear in the fossil record until approximately 425 million years ago, well after the origin of land plants. Double Fertilization is unique to angiosperms: Endosperm results from second sperm nucleus fusing with 2 nuclei in the large center cell of female gametophyte. Fruits attract animals to disperse the seeds. •The angiosperms are the flowering plants.
