Question | Answer |
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 conduct 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 | The outermost appendage of a flower; often small, green, and leaflike. |
petal | One of the appendages of a flower; usually colorful; often functions to attract pollinators. |
stamen | The male reproductive structure of a flower; composed of an anther and a filament. |
pollen | The structure that contains the male gamete of a plant; produced in the anther and covered by a protective coating. |
pistil | The female reproductive part of a flower; includes the stigma, style, and ovary. |
ovary | In plants, the part of the pistil containing ovules and eventually maturing into a fruit surrounding the seeds; in animals and humans, the female reproductive organ that produces eggs |
stigma | The expanded tip of the pistil; receives the pollen. |
pollination | The process of transferring pollen from the anther to the stigma. |
ovule | The structure in a plant ovary that contains the egg and will develop into a seed when fertizilized |
seed | A mature ovule consisting of an embryo and stored food enclosed by a seed coat. |
cotyledon | The source of food in a seed that aids growth; sometimes called a seed leaf. |
fruit | The ripened ovary of a flower. |
