1. Except for the primitive bryophytes (mosses, liverworts, and hornworts), the dominant generation of all plants is the diploid sporophyte generation.
2. All plants possess a cuticle(角质层), a waxy covering on aerial parts that reduces desiccation.
3. The development of a vascular system in plants further reduced their dependency on water.
4. In the more primitive plant divisions, flagellated sperm require water to swim to the eggs. In the more advanced divisions (Coniferophyta and Anthophyta), the sperm, packaged as pollen, are adapted for delivery by wind or animals.
5. In the most advanced division, the Anthophyta, the gametophytes are enclosed (and thus protected) inside an ovary.
6. Plants of the Coniferophyta and Anthophyta have developed adaptations to seasonal variations in the availability of water and light. For example, some trees are deciduous; that is, they shed their leaves to minimize water loss during slow-growing (or dormant) seasons. In contrast, desert annuals will germinate, grow, flower, and produce seeds within brief growing periods in response to a spring rain.
