Roots - underground organ in plants that absorbs water and minerals
Leaves- photosynthetic organs that contain one or more bundles of vascular tissue
Stems - supporting structure that connects roots and leaves and carries water and nutrients between them
Nodes- point on a stem where a leaf is attached
Buds-plant structure containing undeveloped tissue that can produce new stems and leaves.
Pollen Cones-cone in gymnosperms that produces male gametophytes in the form of pollen grains
Seed Cones- cone that produces female gametophytes
Ovules-structure in seed cones in which female gametophytes
Pollen tubes-structure grown by a pollen grain; contains two haploid sperm nuclei
Sepal-outermost circle of flower parts that enclose a bud before it opens and protects the flower while it is developing.
Petal- brightly-colored structure just inside the sepals' attracts insects and other pollinators to a flower
Stamen- male part of the flower, made up of an anther and a filament
Filament- a long thin structure that supports an anther
Anther- flower structure in which haploid male gametophytes are produced
Carpel- innermost part of a flower that produces the female gametophytes
Ovary- in plants, a flower structure that contains one or more ovules from which female gametophytes are produced
Style- narrow stalk of the carpel in a flower
Stigma- sticky portion at the top of the style where pollen grains frequently land
Embryo sac- female gametophyte within the ovule of a flowering plant
Endosperm- food-rich tissue that nourishes a seedling as it grows
Double fertilization- fertilization in angiosperms i which two distinct fertilization events take place between the male and female gametophytes
Dormancy- period of time during which a plant embryo is alive but not growing
Germination-early growth stage of a plant embryo
