All plants can be classified as either bryophytes or tracheophytes. Plants that contain transport vessels (xylem and phloem) are tracheophytes, while those without transport vessels are bryophytes. All plants contain cell walls and chloroplasts, but only a tracheophyte would contain xylem. Plasmids are structures that are almost exclusively found in bacteria or protozoans.

The production of a true flower is one of the defining characteristics of an angiosperm. In fact, angiosperms are also called "flowering plants." Groups of plants that are not angiosperms (think ferns, ginkgos, or pine trees) can have roots and spores and are able to survive in aquatic environments and reproduce vegetative.

Angiosperms are flowering plants. They have both male and female reproductive organs.
The pistil is the female reproductive structure, and consists of three parts. The stigma is the sticky knob used to catch pollen. It is situated at the top of the style, while the ovary contains egg cells and is located below the style.
The stamen is the male reproductive structure, and consists of two parts. The anther produces pollen, and the filament helps in holding up the anther.

Angiosperms are a class of land plant that produces seeds. Angiosperms can be distinguished from gymnosperms by characteristics that include flowers, the presence of endosperm, and fruit production.

Bryophytes are nonvascular plants, such as mosses. Gametophytes are species that have haploid cells during their mature lives, while sporophytes are predominantly diploid during their adult phases.
Bryophytes have the gametophyte generation as dominant, with the sporophytes relying on the parental gametophyte. Starting with the evolution of seedless vascular plants, the gametophytes become reduced and are no longer the dominant life cycle. By the formation of angiosperms (seed plants), the gametophytes have become dependent on the parental sporophyte.

Swimming sperm is a feature of avascular and early vascular plants, who needed to remain in moist environments in order to retain water.
After gaining vascular systems, plants were able to circulate water and nutrients more efficiently, thus being able to grow larger, have more leaves, develop branched systems of roots and shoots to collect water and nutrients, and better dispersal of spores due to gains in size.
