Cellulose, cuticles, and photosynthesis are three adaptations Unlike angiosperms, non-vascular plants do not produce flowers, fruit, or seeds. Pollination occurs when pollen is transferred from the anther to the stigma. These adaptations became the foundation of modern plant anatomy. Because angiosperms photosynthesize so much, they are some of the best oxygen makers around. Seed plants can be divided into two groups: gymnosperms and angiosperms.

There are quite a few adaptions in land animals that help ensure Gymnosperms are seed plants adapted to life on land; thus, they are autotrophic, photosynthetic organisms that tend to conserve water. Not all adaptations appeared at once. Posted on jack wilder and lula kiss by . Various organisms solved these problems in different ways, resulting in physical differences between tissues and chemical alterations that increased the genetic variation of plant species.
