Angiosperms adapt to their environment over time. Angiosperms and gymnosperms both utilize seeds as the primary means of reproduction, and both use pollen to facilitate fertilization. The cuticle, a waxy layer on the surface of leaves and stems, also prevented water loss by reducing evaporation. The earliest reliable record of gymnosperms dates their appearance to the Carboniferous period (359-299 million years ago). Their major adaptions to life on land include a waxy cuticle and root-like structures (rhizoids). Maple trees, and fruit as ways to attract pollinators and rub off pollen help.

Unlike angiosperms, non-vascular plants do not produce flowers, fruit, or seeds. Plants also had to adapt to the new soil conditions on land. . what characteristics help angiosperms adapt to life on land. Angiosperms are able to survive on land thanks to their specialized reproductive processes, vascular tissue, and protective waxy cuticles. 2. Another significant evolutionary advancement over the nonvascular and the more primitive vascular plants is the presence of localized regions for plant growth, called meristems and cambia, which extend the length and width of the plant body, respectively.

They can grow as trees, shrubs, bushes, herbs, and small flowering plants. By contrast, in gymnosperms (e.g., conifers and cycads), the other large group of vascular seed plants, the seeds do not develop enclosed within an ovary but are usually borne exposed on the surfaces of reproductive structures, such as cones. Although the taxonomy of the angiosperms is still incompletely known, the latest classification system incorporates a large body of comparative data derived from studies of DNA sequences. The sporophyte is differentiated into stems, roots, and leaves. Some of the characteristics of angiosperms include: All angiosperms have flowers at some stage in their life.
