Vascular tissue
A plant tissue, such as xylem and phloem, that conducts water and other materials in plants
Nonvascular plant
A plant that lacks the tissues to con- duct water and other materials
Rhizoid
A thin, rootlike structure found in fungi and mosses
Alternation of generations
A reproductive cycle in which the asexual reproductive stages give rise to sexual reproductive stages that, in turn, give rise to asexual reproductive stages
Seedless vascular plant
A plant that has tissues that conduct water and other materials but does not reproduce by forming seeds, such as ferns, club mosses, and horsetails
Seed plant
A vascular plant that produces seeds through sexual reproduction, such as angiosperms and gymnosperms
Angiosperm
A flowering plant that produces seeds surrounded by a protective covering called a fruit
Gymnosperm
A nonflowering plant that produces seeds not fully covered or shielded from the environment
Sepal
One of the outermost appendages of a flower that often appears small, green, and leaflike
Petal
One of the appendages of a flower that is usually colorful and often functions to attract pollinators
Stamen
The male reproductive structure of a flower that is composed of an anther and a filament
Pollen
The structure that contains the male gamete of a plant and is produced in the anther and covered by a protective coating
Pistil
The female reproductive part of a flower, which is composed of the stigma, style, and ovary
Ovary
In plants, the part of the pistil containing ovules and eventually maturing into a fruit surrounding the seeds
Stigma
The expanded tip of the pistil on a flower that receives pollen
