- Anther: The anther is part of the stamen and produces the pollen.
- Articulation: Another term for articulation is internode. Articulation describes the space between two nodes (joints).
- Calyx: The whorl of sepals on the outside of a flower is referred to as the calyx.
- Corolla: The whorl of petals is called the corolla.
- Filament: The filament provides support for the anther in the stamen.
- Floral Axis: The floral axis is the stem holding the reproductive flower parts.
- Microsporangium: The microsprangium is located in the anther and produces microspores, which become male gametophytes. These male gametophytes will later be used in forming the pollen grains.
- Nectary: The nectary produces nectar, a sweet liquid that attracts insects and birds for feeding. As they drink the nectar, the nearby pollen sticks to them and is transported to other flowers.
- Ovary: The ovary houses the ovules and will become the fruit after pollination.
- Ovule: The ovules contain egg cells and become the seeds after pollination.
- Pedicel:The pedicel is the flower stalk.
- Perianth: The perianth is the collective term for the calyx and corolla.
- Petal: The petal is designed to attract pollinators to the flower and protect the stamen and pistil. Many have patterns that can be seen in ultraviolet light by bees and other insects. These indicate where the nectar is located.
- Pistil: The pistil is the female reproductive part in the flower. It includes the ovary, style, and stigma.
- Sepal: Sepals are found on the outside of the flower in a whorl. They are usually green. The group of sepals is called the calyx.
- Stamen: The stamen is the male reproductive organ in the plant. It consists of the anther and filament.
- Stigma: The stigma is the sticky surface where pollen lands and is collected to fertilize the ovules.
- Style: The style is part of the pistil and holds the stigma above the ovary.
